Deforestation refers to the act of clearing trees without replacing them. This often happens when someone is creating land for uses such as settlement and cultivation, among others (Spilsbury 9). Currently, it is one of the biggest threats to human life, owing to the fact that forests provide a support system for all living organisms. Forests are a crucial element of the ecosystem, and human beings have an ethical responsibility to conserve them. However, due to natural occurrences and human activities, a lot of forest cover is lost every year. Deforestation is a global challenge that has caused a lot of pain in different parts of the world. Finding a lasting solution to the problem of deforestation is of paramount importance because its effects are unmanageable.

The challenge of deforestation has existed for centuries, leading to the loss of a huge percentage of forest cover across the world. One of the major causes of deforestation is the increasing need for fuel (Spilsbury 12). It also happens due to the need for more settlement land, the growth of the global timber industry that has increased the demand for commercial items such as furniture, as well as the scarcity of adequate land for cultivation. Wildfires are also a contributor to deforestation, albeit in small percentages compared to the other causes (Spilsbury 19). People should be more environmentally conscious because forest clearing is destroying the ecosystem.

Deforestation causes serious effects on the environment. One of the major effects is the loss of natural habitats for thousands of species. Forests are an essential support system for the livelihoods of many plants and wild animals. Climate change is also caused by deforestation (Spilsbury 27). Over the last century, global weather patterns have drastically changed. Deforestation has resulted in irregular and extreme climatic conditions that have rendered life unbearable. The global temperatures have increased, while the amount of rainfall received has greatly reduced (Spilsbury 32). The lack of trees increases the effect of greenhouse gases, which in turn affects the life cycle.

Deforestation also leads to a general decline in the quality of life. Trees are essential in maintaining the water cycles, reducing soil erosion, and regulating the effect of greenhouse gases (Spilsbury 41). They also help to prevent all types of pollution, which is crucial in maintaining a high quality of life. This element should not be ignored because trees play an important role in the ecosystem. Effective management of deforestation will require all the relevant stakeholders to come up with a strong legal framework.

Deforestation is a serious global challenge that needs to be addressed as soon as possible. It is important for people to understand the value of trees with regard to maintaining the life cycle. This will help in encouraging good stewardship. Several causes of deforestation, such as clearing land for cultivation and settlement, are influenced by human activities. These activities have led to serious effects such as climate change, whose effects are costly to address. Proper coordination between respective government authorities and their citizens can lead to finding a lasting solution to this challenge. It is very important to protect the forests in order to avoid the loss of biodiversity, plant and animal species, as well as manage the effects of climate change.

Introduction:

Deforestation is the process of clearing trees and forest for other uses. Deforestation usually occurs due to city expansion. As habitats increase in cities, there is a need to create more space the for homes, organizations, and factories. This, however, has a damning effect on our environment.

Effect of Deforestation on the Environment:

Deforestation means fewer trees and more land. This has a serious adverse effect on our environment. On one hand, deforestation makes some animals homeless. Animals that survive in the forest might go extinct with less forest. On the other hand, deforestation is also the biggest cause of climate change around the world.

Preventing Deforestation:

Reducing or preventing deforestation is easier said than done. This is because trees are cut down because there is a pressing need to do so. Thus, to prevent deforestation we must try to reduce that need by making smarter choices in paper usage, city planning, migration, etc.

Conclusion:

The essence of plant life in the forest is unquestionable. To ensure a greener environment we must all join the efforts in reducing deforestation.

Deforestation is definitely one of the most troubling of all problems which has plagued our environment. It is important more than ever to take care of the green cover or else it can jeopardize the existence of life on Earth. It is owing to the presence of green trees that we get the oxygen needed to breathe in.

However, because of excessive exploitation by humans, it has been seen that the trees are being cut down mercilessly. This act of cleaning the green cover is known as deforestation.

Educate people:

The best way to handle the problem of deforestation is by making sure that we educate the masses regarding the importance of green cover. When people understand as to how deforestation is leading to grave consequences, they will get the incentive to plant trees rather than uproot them.

Protect the Environment:

As we have continued to exploit the environment in a way that it is hard to get things back to normal, it is now important to immediately start protecting the environment. A lot of natural calamities are occurring these days because the ecosystem balance has been disturbed. Deforestation alone is responsible for a major amount of problems.

So, you need to understand as to how you can come up with ways to excite people about planting more trees and doing their bit for the sake of the environment. Think of your children and grand children. If we continue with our aggressive deforestation campaigns, they are not likely to have a healthy environment for survival. Is that what we really want?

Deforestation can be defined as the removal of trees and clearing of forests for the personal and commercial benefits of human beings. Deforestation has emerged as one of the biggest man-made disasters recently. Every year, more and more trees and vegetation are being erased just to fulfill the various needs of the human race.

Deforestation happens for many reasons. The growing population is one of them. Rising human population needs more area for residential purpose. For this, forests are either burned down or cut to make space for constructing homes and apartments.

Deforestation is also done for commercial purposes. This includes setting up of factories, industries, and towers, etc. The enormous requirements of feeding the human race also create a burden on the land. As a result, clearing land for agricultural purposes leads to deforestation.

Deforestation impacts our earth in several ways. Trees are natural air purifiers. They absorb the carbon dioxide from the air and release oxygen into the atmosphere. Deforestation results in uncontrolled air pollution. When there are fewer trees, there is lesser absorption of carbon dioxide and other pollutants.

Deforestation also disturbs the water cycle. Forests absorb the groundwater and release the water vapors to form clouds, which in turn cause rains. Roots of trees hold the soil intact and prevent floods. But when there are no trees, different kinds of natural calamities are bound to happen.

With deforestation, chances of floods, drought, global warming, and disturbed weather cycle all come into the play. Not only that, the disappearance of forests means the extinction of wild animals and plants, which are highly important parts of our ecosystem.

In order to curb these disasters, we must plant more trees. Restoration of existing vegetation is equally essential. Population control is another indirect method to save trees and forest areas.

Deforestation is the process of cutting down of trees and forests completely or partially for different reasons like manufacturing different products with various parts of the tree as raw material, to build structures and other buildings, etc. Deforestation in recent days has become the curse of our world that resulted in the destruction of nature and the environment.

Cause and Drawbacks:

Deforestation is mainly done for making better living assets for humans and this one side thought is the biggest drawback of this issue. Instead of doing only the cutting part humans should practice forestation along with deforestation. Whenever a tree or a forest is cut, another one should be planted at the same place or on other lands to promote the forestation.

Deforestation is the main cause for many natural deficiencies and the destruction of many animal, plant and bird species. If the practice of cutting down trees continues, then eventually even the world may get destructed along with the extinction of the human race.

It’s not like trees shouldn’t be used for any kind of production and urbanization or industrialization shouldn’t be done for the development, but the main factor is to compensate for every minus done. Through this, there will be a balancing between the reduction and plantation which will help, to an extent, in the rectification of problems faced by the world due to deforestation.

Deforestation has also affected the atmospheric air combination. The carbon content in the atmosphere has considerably increased over years due to many human activities like uncontrolled fuel combustion.

Forest has played a massive function of inhaling the carbon dioxide from the atmosphere and exhaling oxygen during the daytime while they prepare food for themselves. This process is the reason for maintaining a balanced oxygen and carbon level in the atmosphere and that makes the life of us humans to breathe free.

Population growth is undeniably the major factor behind the increased deforestation level. The increased demand for more assets for better living has increased the need for deforestation as well. In such cases forestation should also be made as a follow-up process.

Controlling the overuse of assets can also help in reducing the deforestation rate. If humans start to use products that use a tree as raw material reasonably then it will help in avoiding deforestation as well. Deforestation not only is a life-threatening scenario for many animals and birds, but also the whole human species.

Deforestation refers to the elimination of plants and trees from a region. Deforestation also includes the clearing of jungles and plants from the region due to the numerous commercial motives.

Different Causes of Deforestation:

The below are the different causes of deforestation:

1. Overgrazing:

Overgrazing in jungles finishes recently renewed development. It makes the soil additional compact and invulnerable. The fertility of the soil also reduces owing to the devastation of organic substance. Overgrazing also results in the desertification and the soil erosion. Deforestation results in decreasing the overall soil’s productivity.

2. Shifting Cultivation:

Numerous agriculturalists destroy the jungle for farming and commercial motives and once productiveness of soil is shattered owing to recurrent harvesting, a fresh forest region is devastated. Hence, farmers must be recommended to utilize a similar area for agriculture and use some upgraded farming techniques and stop the deforestation.

3. Fuel Wood:

The maximum amount of forest is destroyed for the fuel wood. Around 86% of the fuel wood is utilized in rural regions in comparison to the 14% in urban parts and hence lead to more deforestation.

4. Forest Fires:

Recurrent fires in the forest regions are one of the major reasons of deforestation. Few incidents of fires are minor whereas the maximum of them are huge.

The industries related to the plywood and timber is mostly accountable for the deforestation. In fact, the huge demand for wooden things has resulted in the quick reduction of the forest.

6. Industry Establishment:

At times the industrial unit is constructed after deforestation. It means for a small achievement of few people, all other people have to bear a permanent loss. In this procedure, wild animals, valuable plant, and unusual birds get devastated. In fact, it adversely affects the quality of the environment.

7. Violation of Forest:

One more reason of deforestation is a violation by tribal on the land of forest for cultivation and other motives. Even though such type of land has a virtuous support for agriculture creation but still it creates environmental threats.

8. Forest Diseases:

Numerous diseases are instigated by rusts, parasitic fungi, nematodes and viruses that result in demise and deterioration of jungle. Fresh saplings are devastated owing to the occurrence of nematodes. Numerous diseases like blister rust, heart rot, and phloem necrosis, oak will, and Dutch elm, etc. destroy the jungle in large quantities.

9. Landslide:

The landslide lead to the deforestation in the mountains is a question of worry. It happened largely in the regions where growing actions are proceeding for the previous few years. The building of highways and railways mainly in hilly lands as well as the structure of large irrigation plans have resulted in enough deforestation and speeded the natural procedure of denudation.

Worldwide Solution for the Deforestation:

The jungle is an essential natural reserve for any nation and deforestation slow down a nation’s growth. To encounter the necessities of the growing population, simple resources might be attained only with the help of afforestation. It is actually the arrangement of implanting plants for food and food growth. Moreover, the nurseries have a significant part in increasing the coverage of the forest area.

Deforestation is the cutting down of trees. It is basically changing the use of land to a different purpose other than the planting of trees.

There are many reasons which have led to large levels of deforestation all over the world. One of the major causes is ever growing population of the world. With the growth in population, the need for more land to live has been rising. This has further led to cutting down of trees. Also, with modernisation, there has been a substantial increase in the requirement of land for setting up of industries. This has again contributed to deforestation.

Mining is another activity of humans which has led to large-scale deforestation in many areas. The need to build road and rail network in order to increase connectivity to the mines has led to cutting down of trees. This has altered the climatic conditions in these areas.

Deforestation has had a huge impact on the environment. Lack of trees has led to less release of water vapour in the air. This has, in turn, led to the alteration of rainfall patterns in different regions. India is a country which is dependent on monsoon rains for agriculture. Frequent droughts and floods caused due to deforestation have affected the lives of many in different parts of the country.

Moreover, trees absorb the carbon-dioxide from the air and help to purify it. Without trees around us, the presence of harmful gases in the air has been rising. This has also led to global warming which is again a major environmental concern. Also, the ever-rising pollution level, especially in many cities in India is due to vast deforestation only.

Additionally, trees bind the soil around them and prevent soil erosion. Deforestation has led to the soil being washed away with winds and rain, making the land unfit for agriculture. Also, trees and forests are the homes to different species of wildlife. With shrinking forests, several of the wildlife has become extinct as they were not able to cope with the changing conditions. Also, there have been increased man and wildlife conflicts in recent times as the animals are forced to venture in the cities in search of food. All these are severe effects of deforestation and need urgent attention by all.

The Perfect Example:

New Delhi is the capital of India. There was once a time when Delhi was a beautiful city. But with modernisation, increase in population, deforestation and mining in the nearby Aravalli hills, Delhi has been reduced to a gas chamber. Such is the impact the Delhi has become one of the most polluted cities in the world. What better example can be there to understand what deforestation has led us to?

There are many ways in which we can reduce deforestation. We must protect our forests. Moreover, we must mark adequate land for our farming needs. There are some laws already in place which prohibit people from unnecessary felling of trees. What needs to be done is the proper execution of the rules so that everyone abides by it. Also, stricter punishments need to be in place for violators so as to deter other people from disobeying the laws. Alternatively, people need to ensure that for every tree felled, equal numbers of trees are planted so that the balance of nature can be maintained. Summarily, it has to be a collective duty of all and just the governments alone, if we really need to reduce deforestation.

It is true that we all need space to live. With the ever-growing population and urbanisation, there has been more than ever need to cut trees and make space. However, we must realise that it is not possible for us to live without having trees around us. Trees bring so many benefits such as giving us oxygen, utilising the harmful carbon dioxide and so many products we need in our daily lives. Without trees around us, there would be no life on the earth. We should all do the needful to protect trees and reduce deforestation.

Deforestation is also known as clearing or clearance of trees. It can be said to mean removal of strands of trees or forests and the conversion of such area of land to a use that is totally non-forest in nature. Some deforestation examples are the converting of areas of forest to urban, ranches or farms use. The area of land that undergoes the most deforestation is the tropical rainforests. It is important to note that forests cover more than 31 percent in total land area of the surface of the earth.

There are a lot of different reasons why deforestation occurs: some tree are being cut down for building or as fuel (timber or coal), while areas of land are to be used as plantation and also as pasture to feed livestock. When trees are removed with properly replacing them, there can as a result be aridity, loss of biodiversity and even habitat damage. We have also had cases of deforestation used in times of war to starve the enemy.

Causes of Deforestation:

It has been discovered that the major and primary deforestation cause is agriculture. Studies have shown that about 48 percent of all deforestation is as a result of subsistence farming and 32 percent of deforestation is as a result of commercial agriculture. Also, it was discovered that logging accounts for about 14% of the total deforestation and 5% is from the removal for fuel wood.

There has been no form of agreement from experts on if industrial form of logging is a very important contributing factor to deforestation globally. Some experts have argued that the clearing of forests is something poor people do more as a result of them not having other alternatives. Other experts are of the belief that the poor seldom clear forests because they do not have the resources needed to do that. A study has also revealed that increase in population as a result of fertility rates that are very high are not a major driver of deforestation and they only influenced less than 8% of the cases of deforestation.

The Environmental Effects of Deforestation:

Deforestation has a lot of negative effects on our planet and environment.

A few of the areas where it negatively affects our environment are discussed below:

i. Atmospheric Effect:

Global warming has deforestation as one of its major contributing factors and deforestation is also a key cause of greenhouse effect. About 20% of all the emission of greenhouse gases is as a result of tropical deforestation. The land in an area that is deforested heats up quicker and it gets to a temperature that is higher than normal, causing a change in solar energy absorption, flow of water vapours and even wind flows and all of these affects the local climate of the area and also the global climate.

Also, the burning of plants in the forest in order to carry out clearing of land, incineration cause a huge amount of carbon dioxide release which is a major and important contributor to the global warming.

ii. Hydrological Effect:

Various researches have shown that deforestation greatly affects water cycle. Groundwater is extracted by trees through the help of their roots; the water extracted is then released into the surrounding atmosphere. If we remove a part of the forest, there will not be transpiration of water like it should be and this result in the climate being a lot drier. The water content of the soil is heavily reduced by deforestation and also atmospheric moisture as well as groundwater. There is a reduced level of water intake that the trees can extract as a result of the dry soil. Soil cohesion is also reduced by deforestation and this can result in landslides, flooding and erosion.

iii. Effect on Soil:

As a direct result of the plant litter on the surface, there is a minimal and reduced erosion rate in forests largely undisturbed. Deforestation increases the erosion rate as a result of the subsequent decrease in the quantity of cover of litter available. The litter cover actually serves as a protection for the soil from all varieties of surface runoff. When mechanized equipments and machineries are used in forestry operations, there can be a resulting erosion increase as a result of the development of roads in the forests.

iv. Effect on Biodiversity:

There is a biodiversity decline due to deforestation. Deforestation can lead to the death and extinction of a lot of species of animals and plants. The habitat of various animals are taken away as a result of deforestation.

The total coverage of forests on the earth’s landmass is 30 percent and the fact the people are destroying them is worrying. Research reveals that majority of the tropical forests on earth are being destroyed. We are almost at half the forest landmass in destruction. How would earth look life without forests? It will be a total disaster if deforestation is encouraged. Deforestation is a human act in which forests are permanently destroyed in order to create settlement area and use the trees for industries like paper manufacture, wood and construction. A lot of forests have been destroyed and the impact has been felt through climate change and extinction of animals due to destruction of the ecosystem. The impacts of deforestation are adverse and there is need to prevent and control it before it can get any worse.

Deforestation is mainly a human activity affected by many factors. Overpopulation contributed to deforestation because there is need to create a settlement area for the increasing number of people on earth and the need for urbanization for economic reasons. Recently, population has greatly risen in the world and people require shelter as a basic need. Forests are destroyed in order for people to find land to build a shelter and then trees are further cut to build those houses. Overpopulation is a major threat to the forest landmass and if not controlled, people will continue to occupy the forests until there is no more forest coverage on earth.

Another factor influencing deforestation is industrialization. Industries that use trees to manufacture their product e.g. paper and wood industries have caused major destruction of forests. The problem with industries is the large-scale need for trees which causes extensive deforestation. The use of timber in industries is a treat to forests all over the world. In as much as we need furniture, paper and homes, it is not worth the massive destruction of our forests.

Fires are also a cause of deforestation. During episodes of drought, fire spreads widely and burns down trees. The fire incidences could result from human activities like smoking or charcoal burning in the forests. Drought due to adverse weather changes in global warming is a natural disaster that claim the lives of people and living things.

Agricultural activities such as farming and livestock keeping also cause deforestation because of the land demand in those activities. Deforestation for farming purpose involves clearing all the vegetation on the required land and using it for and then burring the vegetation hence the name ‘slash and burn agriculture’. The ranches required for cattle keeping among other livestock require a large area that is clear from trees.

Impacts of Deforestation:

Deforestation has a great impact on the ecosystem in different ways. Climate change is influenced by deforestation because trees influence weather directly. Trees usually act to protect against strong winds and erosion but in its absence, natural disasters like floods and storms could be experienced. Also, tree are important in replenishing the air in the atmosphere. Trees have the ability to absorb carbon dioxide from the atmosphere and release oxygen. Without trees, the concentration of carbon dioxide in the atmosphere will be increased. Because carbon dioxide is a greenhouse gas, it causes global warming.

Global warming is a serious environmental issue that causes adverse climatic changes and affects life on earth. Extreme weather conditions like storms, drought and floods. These weather conditions are not conducive for humans and other living things on earth. Natural disasters as a result of global warming are very destructive both to animate and inanimate objects in the environment.

Loss of species due to deforestation has negatively affected biodiversity. Biodiversity is a highly valued aspect of life on earth and its interruption is a loss. There is a loss of habitat for species to exist in as a result of deforestation and therefore species face extinction. Extinction of some rare species is a threat we are currently facing. Animals that live and depend on forest vegetation for food will also suffer and eventually die of hunger. Survival has been forced on animals of the jungle due to deforestation and that is why human wildlife conflict is being experienced.

The water cycle on earth is negatively affected by deforestation. The existence of water vapor in the atmosphere is maintained by trees. Absence of trees cause a reduced vapor retention in the atmosphere which result in adverse climate changes. Trees and other forest vegetation are important in preventing water pollution because they prevent the contaminated runoff into water sources like rivers, lakes and oceans. Without trees, pollution of water is more frequent and therefore the water will be unsafe for consumption by human and animals.

Solutions to Deforestation:

Based on the serious impact of deforestation, it is only safe if solutions are sought to end this problem. The ultimate solution is definitely restoration of the forest landmass on earth. The restoration can be done by encouraging the planting of trees, a process called reforestation. Although reforestation will not completely solve the impacts of deforestation, it will restore a habitat for the wild animals and slowly restore the ecosystem. Major impacts like concentration of carbon dioxide in the atmosphere require another approach. Human activities that contribute to carbon dioxide gas emission to the atmosphere have to be reduced through strict policies for industries and finding alternative energy sources that do not produce greenhouse gases.

Another solution is public awareness. People have to be made aware that deforestation has negative effects so that they can reduce the act. Through awareness, people can also be taught on ways of reducing the population e.g., family planning. On World Environment Day, people are encouraged to participate in activities like tree planting in order to conserve environment and that is how the awareness takes place.

In conclusion, deforestation is a human activity that is destructive and should be discouraged. Environmental conservation is our responsibility because we have only one earth to live in.

In this paper we afford a quantitative analysis of the sustainability of current world population growth in relation to the parallel deforestation process adopting a statistical point of view. We consider a simplified model based on a stochastic growth process driven by a continuous time random walk, which depicts the technological evolution of human kind, in conjunction with a deterministic generalised logistic model for humans-forest interaction and we evaluate the probability of avoiding the self-destruction of our civilisation. Based on the current resource consumption rates and best estimate of technological rate growth our study shows that we have very low probability, less than 10% in most optimistic estimate, to survive without facing a catastrophic collapse.

Introduction.

In the last few decades, the debate on climate change has assumed global importance with consequences on national and global policies. Many factors due to human activity are considered as possible responsible of the observed changes: among these water and air contamination (mostly greenhouse effect) and deforestation are the mostly cited. While the extent of human contribution to the greenhouse effect and temperature changes is still a matter of discussion, the deforestation is an undeniable fact. Indeed before the development of human civilisations, our planet was covered by 60 million square kilometres of forest 1 . As a result of deforestation, less than 40 million square kilometres currently remain 2 . In this paper, we focus on the consequence of indiscriminate deforestation.

Trees’ services to our planet range from carbon storage, oxygen production to soil conservation and water cycle regulation. They support natural and human food systems and provide homes for countless species, including us, through building materials. Trees and forests are our best atmosphere cleaners and, due to the key role they play in the terrestrial ecosystem, it is highly unlikely to imagine the survival of many species, including ours, on Earth without them. In this sense, the debate on climate change will be almost obsolete in case of a global deforestation of the planet. Starting from this almost obvious observation, we investigate the problem of the survival of humanity from a statistical point of view. We model the interaction between forests and humans based on a deterministic logistic-like dynamics, while we assume a stochastic model for the technological development of the human civilisation. The former model has already been applied in similar contexts 3 , 4 while the latter is based on data and model of global energy consumption 5 , 6 used as a proxy for the technological development of a society. This gives solidity to our discussion and we show that, keeping the current rate of deforestation, statistically the probability to survive without facing a catastrophic collapse, is very low. We connect such probability to survive to the capability of humankind to spread and exploit the resources of the full solar system. According to Kardashev scale 7 , 8 , which measures a civilisation’s level of technological advancement based on the amount of energy they are able to use, in order to spread through the solar system we need to be able to harness the energy radiated by the Sun at a rate of ≈4 × 10 26 Watt. Our current energy consumption rate is estimated in ≈10 13 Watt 9 . As showed in the subsections “Statistical Model of technological development” and “Numerical results” of the following section, a successful outcome has a well defined threshold and we conclude that the probability of avoiding a catastrophic collapse is very low, less than 10% in the most optimistic estimate.

Model and Results

Deforestation.

The deforestation of the planet is a fact 2 . Between 2000 and 2012, 2.3 million Km 2 of forests around the world were cut down 10 which amounts to 2 × 10 5 Km 2 per year. At this rate all the forests would disappear approximatively in 100–200 years. Clearly it is unrealistic to imagine that the human society would start to be affected by the deforestation only when the last tree would be cut down. The progressive degradation of the environment due to deforestation would heavily affect human society and consequently the human collapse would start much earlier.

Curiously enough, the current situation of our planet has a lot in common with the deforestation of Easter Island as described in 3 . We therefore use the model introduced in that reference to roughly describe the humans-forest interaction. Admittedly, we are not aiming here for an exact exhaustive model. It is probably impossible to build such a model. What we propose and illustrate in the following sections, is a simplified model which nonetheless allows us to extrapolate the time scales of the processes involved: i.e. the deterministic process describing human population and resource (forest) consumption and the stochastic process defining the economic and technological growth of societies. Adopting the model in 3 (see also 11 ) we have for the humans-forest dynamics

where N represent the world population and R the Earth surface covered by forest. β is a positive constant related to the carrying capacity of the planet for human population, r is the growth rate for humans (estimated as r  ~ 0.01 years −1 ) 12 , a 0 may be identified as the technological parameter measuring the rate at which humans can extract the resources from the environment, as a consequence of their reached technological level. r ’ is the renewability parameter representing the capability of the resources to regenerate, (estimated as r ’ ~ 0.001 years −1 ) 13 , R c the resources carrying capacity that in our case may be identified with the initial 60 million square kilometres of forest. A closer look at this simplified model and at the analogy with Easter Island on which is based, shows nonetheless, strong similarities with our current situation. Like the old inhabitants of Easter Island we too, at least for few more decades, cannot leave the planet. The consumption of the natural resources, in particular the forests, is in competition with our technological level. Higher technological level leads to growing population and higher forest consumption (larger a 0 ) but also to a more effective use of resources. With higher technological level we can in principle develop technical solutions to avoid/prevent the ecological collapse of our planet or, as last chance, to rebuild a civilisation in the extraterrestrial space (see section on the Fermi paradox). The dynamics of our model for humans-forest interaction in Eqs. ( 1 , 2 ), is typically characterised by a growing human population until a maximum is reached after which a rapid disastrous collapse in population occurs before eventually reaching a low population steady state or total extinction. We will use this maximum as a reference for reaching a disastrous condition. We call this point in time the “no-return point” because if the deforestation rate is not changed before this time the human population will not be able to sustain itself and a disastrous collapse or even extinction will occur. As a first approximation 3 , since the capability of the resources to regenerate, r ′, is an order of magnitude smaller than the growing rate for humans, r , we may neglect the first term in the right hand-side of Eq. ( 2 ). Therefore, working in a regime of the exploitation of the resources governed essentially by the deforestation, from Eq. ( 2 ) we can derive the rate of tree extinction as

The actual population of the Earth is N  ~ 7.5 × 10 9 inhabitants with a maximum carrying capacity estimated 14 of N c  ~ 10 10 inhabitants. The forest carrying capacity may be taken as 1 R c  ~ 6 × 10 7 Km 2 while the actual surface of forest is \(R\lesssim 4\times {10}^{7}\) Km 2 . Assuming that β is constant, we may estimate this parameter evaluating the equality N c ( t ) =  βR ( t ) at the time when the forests were intact. Here N c ( t ) is the instantaneous human carrying capacity given by Eq. ( 1 ). We obtain β  ~  N c / R c  ~ 170.

In alternative we may evaluate β using actual data of the population growth 15 and inserting it in Eq. ( 1 ). In this case we obtain a range \(700\lesssim \beta \lesssim 900\) that gives a slightly favourable scenario for the human kind (see below and Fig.  4 ). We stress anyway that this second scenario depends on many factors not least the fact that the period examined in 15 is relatively short. On the contrary β  ~ 170 is based on the accepted value for the maximum human carrying capacity. With respect to the value of parameter a 0 , adopting the data relative to years 2000–2012 of ref. 10 ,we have

The time evolution of system ( 1 ) and ( 2 ) is plotted in Figs.  1 and 2 . We note that in Fig.  1 the numerical value of the maximum of the function N ( t ) is N M  ~ 10 10 estimated as the carrying capacity for the Earth population 14 . Again we have to stress that it is unrealistic to think that the decline of the population in a situation of strong environmental degradation would be a non-chaotic and well-ordered decline, that is also way we take the maximum in population and the time at which occurs as the point of reference for the occurrence of an irreversible catastrophic collapse, namely a ‘no-return’ point.

Statistical model of technological development

According to Kardashev scale 7 , 8 , in order to be able to spread through the solar system, a civilisation must be capable to build a Dyson sphere 16 , i.e. a maximal technological exploitation of most the energy from its local star, which in the case of the Earth with the Sun would correspond to an energy consumption of E D  ≈ 4 × 10 26 Watts, we call this value Dyson limit. Our actual energy consumption is estimated in E c  ≈ 10 13 Watts (Statistical Review of World Energy source) 9 . To describe our technological evolution, we may roughly schematise the development as a dichotomous random process

where T is the level of technological development of human civilisation that we can also identify with the energy consumption. α is a constant parameter describing the technological growth rate (i.e. of T ) and ξ ( t ) a random variable with values 0, 1. We consider therefore, based on data of global energy consumption 5 , 6 an exponential growth with fluctuations mainly reflecting changes in global economy. We therefore consider a modulated exponential growth process where the fluctuations in the growth rate are captured by the variable ξ ( t ). This variable switches between values 0, 1 with waiting times between switches distributed with density ψ ( t ). When ξ ( t ) = 0 the growth stops and resumes when ξ switches to ξ ( t ) = 1. If we consider T more strictly as describing the technological development, ξ ( t ) reflects the fact that investments in research can have interruptions as a consequence of alternation of periods of economic growth and crisis. With the following transformation,

differentiating both sides respect to t and using Eq. ( 5 ), we obtain for the transformed variable W

where \(\bar{\xi }(t)=2[\xi (t)-\langle \xi \rangle ]\) and 〈ξ 〉 is the average of ξ ( t ) so that \(\bar{\xi }(t)\) takes the values ±1.

The above equation has been intensively studied, and a general solution for the probability distribution P ( W , t ) generated by a generic waiting time distribution can be found in literature 17 . Knowing the distribution we may evaluate the first passage time distribution in reaching the necessary level of technology to e.g. live in the extraterrestrial space or develop any other way to sustain population of the planet. This characteristic time has to be compared with the time that it will take to reach the no-return point. Knowing the first passage time distribution 18 we will be able to evaluate the probability to survive for our civilisation.

If the dichotomous process is a Poissonian process with rate γ then the correlation function is an exponential, i.e.

and Eq. ( 7 ) generates for the probability density the well known telegrapher’s equation

We note that the approach that we are following is based on the assumption that at random times, exponentially distributed with rate γ , the dichotomous variable \(\bar{\xi }\) changes its value. With this assumption the solution to Eq. ( 9 ) is

where I n ( z ) are the modified Bessel function of the first kind. Transforming back to the variable T we have

where for sake of compactness we set

In Laplace transform we have

The first passage time distribution, in laplace transform, is evaluated as 19

Inverting the Laplace transform we obtain

which is confirmed (see Fig.  3 ) by numerical simulations. The time average to get the point x for the first time is given by

which interestingly is double the time it would take if a pure exponential growth occurred, depends on the ratio between final and initial value of T and is independent of γ . We also stress that this result depends on parameters directly related to the stage of development of the considered civilisation, namely the starting value T 1 , that we assume to be the energy consumption E c of the fully industrialised stage of the civilisation evolution and the final value T , that we assume to be the Dyson limit E D , and the technological growth rate α . For the latter we may, rather optimistically, choose the value α  = 0.345, following the Moore Law 20 (see next section). Using the data above, relative to our planet’s scenario, we obtain the estimate of 〈 t 〉 ≈ 180 years. From Figs.  1 and 2 we see that the estimate for the no-return time are 130 and 22 years for β  = 700 and β  = 170 respectively, with the latter being the most realistic value. In either case, these estimates based on average values, being less than 180 years, already portend not a favourable outcome for avoiding a catastrophic collapse. Nonetheless, in order to estimate the actual probability for avoiding collapse we cannot rely on average values, but we need to evaluate the single trajectories, and count the ones that manage to reach the Dyson limit before the ‘no-return point’. We implement this numerically as explained in the following.

(Right panel) 2D plot of p suc for a  = 1.5 × 10 −4 Km 2 ys −1 as a function of α . Red line is p suc for β  = 170. Black continuous lines (indistinguishable) are p suc for β  = 300 and 700 respectively (see also Fig.  6 ). Green dashed line indicates the value of α corresponding to Moore’s law.

Numerical results

We run simulations of Eqs. ( 1 ), ( 2 ) and ( 5 ) simultaneously for different values of of parameters a 0 and α for fixed β and we count the number of trajectories that reach Dyson limit before the population level reaches the “no-return point” after which rapid collapse occurs. More precisely, the evolution of T is stochastic due to the dichotomous random process ξ ( t ), so we generate the T ( t ) trajectories and at the same time we follow the evolution of the population and forest density dictated by the dynamics of Eqs. ( 1 ), ( 2 ) 3 until the latter dynamics reaches the no-return point (maximum in population followed by collapse). When this happens, if the trajectory in T ( t ) has reached the Dyson limit we count it as a success, otherwise as failure. This way we determine the probabilities and relative mean times in Figs.  5 , 6 and 7 . Adopting a weak sustainability point of view our model does not specify the technological mechanism by which the successful trajectories are able to find an alternative to forests and avoid collapse, we leave this undefined and link it exclusively and probabilistically to the attainment of the Dyson limit. It is important to notice that we link the technological growth process described by Eq. ( 5 ) to the economic growth and therefore we consider, for both economic and technological growth, a random sequence of growth and stagnation cycles, with mean periods of about 1 and 4 years in accordance with estimates for the driving world economy, i.e. the United States according to the National Bureau of Economic Research 21 .

Probability of reaching Dyson value p suc before reaching “no-return” point as function of β and α for a  = 1.5 × 10 −4 Km 2 ys −1 .

In Eq. ( 1 , 2 ) we redefine the variables as N ′ =  N / R W and R ′ =  R / R W with \({R}_{W}\simeq 150\times {10}^{6}\,K{m}^{2}\) the total continental area, and replace parameter a 0 accordingly with a  =  a 0  ×  R W  = 1.5 × 10 −4 Km 2 ys −1 . We run simulations accordingly starting from values \({R{\prime} }_{0}\) and \({N{\prime} }_{0}\) , based respectively on the current forest surface and human population. We take values of a from 10 −5 to 3 × 10 −4 Km 2 ys −1 and for α from 0.01 ys −1 to 4.4 ys −1 . Results are shown in Figs.  4 and 6 . Figure  4 shows a threshold value for the parameter α , the technological growth rate, above which there is a non-zero probability of success. This threshold value increases with the value of the other parameter a . As shown in Fig.  7 this values depends as well on the value of β and higher values of β correspond to a more favourable scenario where the transition to a non-zero probability of success occurs for smaller α , i.e. for smaller, more accessible values, of technological growth rate. More specifically, left panel of Fig.  4 shows that, for the more realistic value β  = 170, a region of parameter values with non-zero probability of avoiding collapse corresponds to values of α larger than 0.5. Even assuming that the technological growth rate be comparable to the value α  = log(2)/2 = 0.345 ys −1 , given by the Moore Law (corresponding to a doubling in size every two years), therefore, it is unlikely in this regime to avoid reaching the the catastrophic ‘no-return point’. When the realistic value of a  = 1.5 × 10 4 Km 2 ys −1 estimated from Eq. ( 4 ), is adopted, in fact, a probability less than 10% is obtained for avoiding collapse with a Moore growth rate, even when adopting the more optimistic scenario corresponding to β  = 700 (black curve in right panel of Fig.  4 ). While an α larger than 1.5 is needed to have a non-zero probability of avoiding collapse when β  = 170 (red curve, same panel). As far as time scales are concerned, right panel of Fig.  5 shows for β  = 170 that even in the range α  > 0.5, corresponding to a non-zero probability of avoiding collapse, collapse is still possible, and when this occurs, the average time to the ‘no-return point’ ranges from 20 to 40 years. Left panel in same figure, shows for the same parameters, that in order to avoid catastrophe, our society has to reach the Dyson’s limit in the same average amount of time of 20–40 years.

In Fig.  7 we show the dependence of the model on the parameter β for a  = 1.5 × 10 −4 .

We run simulations of Eqs. ( 1 ), ( 2 ) and ( 5 ) simultaneously for different values of of parameters a 0 and α depending on β as explained in Methods and Results to generate Figs.  5 , 6 and 7 . Equations ( 1 ), ( 2 ) are integrated via standard Euler method. Eq. ( 5 ) is integrated as well via standard Euler method between the random changes of the variable ξ . The stochastic dichotomous process ξ is generated numerically in the following way: using the random number generator from gsl library we generate the times intervals between the changes of the dichotomous variable ξ  = 0, 1, with an exponential distribution(with mean values of 1 and 4 years respectively), we therefore obtain a time series of 0 and 1 for each trajectory. We then integrate Eq. ( 5 ) in time using this time series and we average over N  = 10000 trajectories. The latter procedure is used to carry out simulations in Figs.  3 and 4 as well in order to evaluate the first passage time probabilities. All simulations are implemented in C++.

Fermi paradox

In this section we briefly discuss a few considerations about the so called Fermi paradox that can be drawn from our model. We may in fact relate the Fermi paradox to the problem of resource consumption and self destruction of a civilisation. The origin of Fermi paradox dates back to a casual conversation about extraterrestrial life that Enrico Fermi had with E. Konopinski, E. Teller and H. York in 1950, during which Fermi asked the famous question: “where is everybody?”, since then become eponymous for the paradox. Starting from the closely related Drake equation 22 , 23 , used to estimate the number of extraterrestrial civilisations in the Milky Way, the debate around this topic has been particularly intense in the past (for a more comprehensive covering we refer to Hart 24 , Freitas 25 and reference therein). Hart’s conclusion is that there are no other advanced or ‘technological’ civilisations in our galaxy as also supported recently by 26 based on a careful reexamination of Drake’s equation. In other words the terrestrial civilisation should be the only one living in the Milk Way. Such conclusions are still debated, but many of Hart’s arguments are undoubtedly still valid while some of them need to be rediscussed or updated. For example, there is also the possibility that avoiding communication might actually be an ‘intelligent’ choice and a possible explanation of the paradox. On several public occasions, in fact, Professor Stephen Hawking suggested human kind should be very cautious about making contact with extraterrestrial life. More precisely when questioned about planet Gliese 832c’s potential for alien life he once said: “One day, we might receive a signal from a planet like this, but we should be wary of answering back”. Human history has in fact been punctuated by clashes between different civilisations and cultures which should serve as caveat. From the relatively soft replacement between Neanderthals and Homo Sapiens (Kolodny 27 ) up to the violent confrontation between native Americans and Europeans, the historical examples of clashes and extinctions of cultures and civilisations have been quite numerous. Looking at human history Hawking’s suggestion appears as a wise warning and we cannot role out the possibility that extraterrestrial societies are following similar advice coming from their best minds.

With the help of new technologies capable of observing extrasolar planetary systems, searching and contacting alien life is becoming a concrete possibility (see for example Grimaldi 28 for a study on the chance of detecting extraterrestrial intelligence), therefore a discussion on the probability of this occurring is an important opportunity to assess also our current situation as a civilisation. Among Hart’s arguments, the self-destruction hypothesis especially needs to be rediscussed at a deeper level. Self-destruction following environmental degradation is becoming more and more an alarming possibility. While violent events, such as global war or natural catastrophic events, are of immediate concern to everyone, a relatively slow consumption of the planetary resources may be not perceived as strongly as a mortal danger for the human civilisation. Modern societies are in fact driven by Economy, and, without giving here a well detailed definition of “economical society”, we may agree that such a kind of society privileges the interest of its components with less or no concern for the whole ecosystem that hosts them (for more details see 29 for a review on Ecological Economics and its criticisms to mainstream Economics). Clear examples of the consequences of this type of societies are the international agreements about Climate Change. The Paris climate agreement 30 , 31 is in fact, just the last example of a weak agreement due to its strong subordination to the economic interests of the single individual countries. In contraposition to this type of society we may have to redefine a different model of society, a “cultural society”, that in some way privileges the interest of the ecosystem above the individual interest of its components, but eventually in accordance with the overall communal interest. This consideration suggests a statistical explanation of Fermi paradox: even if intelligent life forms were very common (in agreement with the mediocrity principle in one of its version 32 : “there is nothing special about the solar system and the planet Earth”) only very few civilisations would be able to reach a sufficient technological level so as to spread in their own solar system before collapsing due to resource consumption.

We are aware that several objections can be raised against this argument and we discuss below the one that we believe to be the most important. The main objection is that we do not know anything about extraterrestrial life. Consequently, we do not know the role that a hypothetical intelligence plays in the ecosystem of the planet. For example not necessarily the planet needs trees (or the equivalent of trees) for its ecosystem. Furthermore the intelligent form of life could be itself the analogous of our trees, so avoiding the problem of the “deforestation” (or its analogous). But if we assume that we are not an exception (mediocrity principle) then independently of the structure of the alien ecosystem, the intelligent life form would exploit every kind of resources, from rocks to organic resources (animal/vegetal/etc), evolving towards a critical situation. Even if we are at the beginning of the extrasolar planetology, we have strong indications that Earth-like planets have the volume magnitude of the order of our planet. In other words, the resources that alien civilisations have at their disposal are, as order of magnitude, the same for all of them, including ourselves. Furthermore the mean time to reach the Dyson limit as derived in Eq.  6 depends only on the ratio between final and initial value of T and therefore would be independent of the size of the planet, if we assume as a proxy for T energy consumption (which scales with the size of the planet), producing a rather general result which can be extended to other civilisations. Along this line of thinking, if we are an exception in the Universe we have a high probability to collapse or become extinct, while if we assume the mediocrity principle we are led to conclude that very few civilisations are able to reach a sufficient technological level so as to spread in their own solar system before the consumption of their planet’s resources triggers a catastrophic population collapse. The mediocrity principle has been questioned (see for example Kukla 33 for a critical discussion about it) but on the other hand the idea that the humankind is in some way “special” in the universe has historically been challenged several times. Starting with the idea of the Earth at the centre of the universe (geocentrism), then of the solar system as centre of the universe (Heliocentrism) and finally our galaxy as centre of the universe. All these beliefs have been denied by the facts. Our discussion, being focused on the resource consumption, shows that whether we assume the mediocrity principle or our “uniqueness” as an intelligent species in the universe, the conclusion does not change. Giving a very broad meaning to the concept of cultural civilisation as a civilisation not strongly ruled by economy, we suggest for avoiding collapse 34 that only civilisations capable of such a switch from an economical society to a sort of “cultural” society in a timely manner, may survive. This discussion leads us to the conclusion that, even assuming the mediocrity principle, the answer to “Where is everybody?” could be a lugubrious “(almost) everyone is dead”.

Conclusions

In conclusion our model shows that a catastrophic collapse in human population, due to resource consumption, is the most likely scenario of the dynamical evolution based on current parameters. Adopting a combined deterministic and stochastic model we conclude from a statistical point of view that the probability that our civilisation survives itself is less than 10% in the most optimistic scenario. Calculations show that, maintaining the actual rate of population growth and resource consumption, in particular forest consumption, we have a few decades left before an irreversible collapse of our civilisation (see Fig.  5 ). Making the situation even worse, we stress once again that it is unrealistic to think that the decline of the population in a situation of strong environmental degradation would be a non-chaotic and well-ordered decline. This consideration leads to an even shorter remaining time. Admittedly, in our analysis, we assume parameters such as population growth and deforestation rate in our model as constant. This is a rough approximation which allows us to predict future scenarios based on current conditions. Nonetheless the resulting mean-times for a catastrophic outcome to occur, which are of the order of 2–4 decades (see Fig.  5 ), make this approximation acceptable, as it is hard to imagine, in absence of very strong collective efforts, big changes of these parameters to occur in such time scale. This interval of time seems to be out of our reach and incompatible with the actual rate of the resource consumption on Earth, although some fluctuations around this trend are possible 35 not only due to unforeseen effects of climate change but also to desirable human-driven reforestation. This scenario offers as well a plausible additional explanation to the fact that no signals from other civilisations are detected. In fact according to Eq. ( 16 ) the mean time to reach Dyson sphere depends on the ratio of the technological level T and therefore, assuming energy consumption (which scales with the size of the planet) as a proxy for T , such ratio is approximately independent of the size of the planet. Based on this observation and on the mediocrity principle, one could extend the results shown in this paper, and conclude that a generic civilisation has approximatively two centuries starting from its fully developed industrial age to reach the capability to spread through its own solar system. In fact, giving a very broad meaning to the concept of cultural civilisation as a civilisation not strongly ruled by economy, we suggest that only civilisations capable of a switch from an economical society to a sort of “cultural” society in a timely manner, may survive.

Deforestation in the United States: causes, consequences, and cures

• Share this article:

Deforestation is the widespread clearing of forests and is a global issue with far-reaching consequences. While deforestation often brings to mind images of the Amazon Rainforest, it is crucial to recognise that it also affects other regions, including the United States of America. In this blog, we’ll explore the causes and impact of deforestation in the United States, examine notable case studies, and discuss ongoing conservation efforts to address this pressing environmental issue.

The United States boasts the world's fourth-largest forest estate, encompassing approximately 8% of global forests. With almost 766 million acres of forested land, forests cover about one-third of the country's total land area. From the breathtaking boreal forests of Alaska to the vibrant deciduous forests in the eastern region, the sprawling pine plantations in the southern states, the enchanting temperate rainforests along the West Coast, and even the tropical rainforests in Puerto Rico and Hawaii, the diversity of American forests is remarkable. While 69% of these forests are under private ownership , the remaining lands are carefully managed by local, tribal, state, and federal governments to preserve their ecological integrity.

Causes of deforestation in the United States 

In the United States, forested lands serve various purposes , with some designated for production and others preserved for conservation. However, a significant portion of forested lands falls under the category of multiple-use forestland, managed for a combination of production, recreation, habitat preservation, and aesthetic value. 

The recognised timberland, primarily used for production, spans an extensive area of 521 million acres. Alongside these production-focused areas, there are reserved forests covering 75 million acres that are specifically preserved and not managed for timber harvest. These areas exclude protected areas like national forest roadless areas. The United States also boasts 187 million acres of other forest types, including woodlands, scrub forests, and urban forests.

Unfortunately, the United States faces deforestation at significant rates: In 2021 alone, it lost 4.22 million acres of forest, equivalent to 775 million tonnes of carbon dioxide emissions. There are many root causes of deforestation . Here are five of the most prevalent causes of deforestation in the United States: 

Logging and timber industries : The demand for timber products drives extensive logging activities across the country, particularly in regions like the Pacific Northwest. The United States is one of the largest consumers and producers of timber globally, being the top global producer of industrial roundwood, wood pellets, and pulp for the paper industry. This contributes significantly to deforestation within its borders. It occurs most prevalently in Oregon, Washington, and Georgia.

Agriculture and expansion of croplands : To meet the growing demand for food and biofuel production, vast areas of forests are cleared for agricultural  production, including soy, corn, and palm oil production. This practice is prevalent in the Southeastern United States, where forests are converted into croplands. Between 1982 and 1997, approximately 55% of land that transitioned into agricultural use originated from forested areas . This shift reflected a continued conversion of land from less intensive uses, such as forests, to more agriculturally focused uses, including cropland and pasture .

Urbanisation and infrastructure development : Rapid urban growth leads to the conversion of forests into residential areas, commercial spaces, and infrastructure projects, becoming a significant driver of deforestation. The construction of roads, highways, and industrial zones often involves clearing large swaths of forests, leading to habitat loss and fragmentation.

Natural disasters and wildfires : While natural disturbances like hurricanes, tornadoes, and wildfires are part of the ecosystem, their frequency and intensity have increased due to climatic instability. These events can result in significant forest loss and hinder reforestation efforts. California has become the most wildfire-prone state in the US, while on the other coast, Florida is the state most affected by hurricanes .

Illegal logging and unsustainable practices : Despite regulations, illegal deforestation activities persist, causing substantial damage to forests. Unsustainable practices, such as clear-cutting and selective logging, degrade forest ecosystems and contribute to deforestation leading to a loss of habitat for many wild animal species and environmental degradation .

The impact of deforestation in the United States

Deforestation has many far-reaching effects. Florida, Alaska, Alabama, Georgia, and Mississippi have experienced significant deforestation loss within the United States. Over the centuries, the country has witnessed the destruction of a staggering 75% of its virgin forests (since the 1600s). 

Between 2001 and 2020, the United States lost approximately 104 million acres of forests, resulting in a substantial 15% decrease in tree cover. These alarming statistics highlight the urgent need for conservation efforts and sustainable practices to address the ongoing issue of deforestation in the country and its effects. Here are some of the most prevalent effects of deforestation in the United States:

Loss of biodiversity and habitat destruction: Forests are home to a rich variety of plant and animal species. Deforestation disrupts ecosystems , leading to the loss of habitats and the endangerment or extinction of numerous species. The United States is home to diverse flora and fauna, some of which are unique to North America, such as the elk, bison, bald eagle, and California condor, making habitat preservation vital for biodiversity conservation.

Increased carbon emissions: Forests act as carbon sinks, absorbing large amounts of carbon dioxide from the atmosphere and mitigating climatic instability. When forests are cleared, carbon is released back into the atmosphere, exacerbating the greenhouse effect. Deforestation in the United States therefore contributes to increased carbon and greenhouse gas emissions, impacting global climate patterns.

Soil erosion and degradation : Forests play a key role in soil conservation, preventing erosion, and maintaining soil fertility. Deforestation disrupts this balance, increasing soil erosion and nutrient depletion and decreasing agricultural productivity.

Water cycle disruption and increased flooding : Forests are vital for regulating the water  cycle and ensuring the availability of freshwater resources. Deforestation disrupts this cycle, altering rainfall patterns and increasing the risk of flooding and droughts in affected areas.

Impact on Indigenous communities and cultural heritage : Forests hold immense cultural and spiritual significance for Indigenous communities in the United States. Deforestation encroaches upon their ancestral lands, threatening their way of life, traditional knowledge, and cultural heritage.

Case studies of deforestation in the United States

Deforestation takes many forms and carries many consequences. With such a biodiverse landscape in the US, it is essential to assess how deforestation manifests in various locations. Here are three case studies of deforestation in the United States:

Deforestation in the Pacific Northwest

The Pacific Northwest, renowned for its rich biodiversity, has been significantly impacted by extensive logging activities, resulting in habitat loss for various species, including the northern spotted owl. 

Approximately 13% of the Pacific Northwest's old-growth forests were lost to logging within slightly more than 10 years, with most of the loss occurring on non-federal lands. NASA's recent satellite and space radar images vividly portray the decline of forests in Washington and Oregon—a consequence of development, agriculture, and extensive logging. 

In this region, which includes California, nearly 50% of forests are owned by the US government, with federal lands containing around 67% of the highly carbon-rich and biodiverse old-growth forests. From 1994 to 2007, roughly 1.9% of old-growth forests on federal lands experienced loss. Notably, logging accounted for less than 0.5% of the loss (equivalent to approximately 32,000 acres), while the remainder (around 80,937 acres) was attributed to wildfires.

Deforestation in the Southeastern United States

The forest products industry in the Southern United States has played a significant role in forest clearing and the transformation of natural forests into monoculture pine plantations. According to a study on global forest cover loss published in ScienceDaily , the level of forest disturbance in Southeastern US forests from 2000 to 2012 was four times higher than that of Brazil. 

Industrial logging in the subtropical forests of the Southeastern US was identified as a major driver of this trend. As a result, over 31% of forest cover in the Southeastern US has been lost or replaced mostly in favour of agricultural lands (for example, palm oil plantations). Landowners in this region use timber harvesting practices where trees are swiftly harvested and replaced, treating them as agricultural crops. 

This approach has led to a highly dynamic landscape characterised by substantial tree loss and gain. Loblolly and slash pine, which were once a small portion of the natural pine forest, now dominate the Coastal Plain landscape. In contrast, the extensive longleaf pine savannas that were once abundant have been significantly reduced in size. Furthermore, the historical draining and ditching of wetland forests to make way for intensively managed pine plantations have altered the hydrological function of entire watersheds.

Deforestation in Alaska and the impact on wildlife 

Climate change and the increased release of greenhouse gases in the atmosphere have led to the melting of Arctic ice, opening up new areas for resource extraction in Alaska. The loss of forests in the region, mainly due to wildfires, logging or road construction, threatens wildlife habitat for the caribou, polar bears, and migratory birds, with potential long-term ecological consequences. Alaska lost the largest amount of forest tree cover of all US states, losing almost 11% of its tree cover between 2001 and 2021.

Extra: Deforestation in the Amazon Rainforest due to American companies : While not within the borders of the United States, American companies contribute to deforestation in the Amazonian tropical forest through activities such as cattle ranching and soybean cultivation.

Conservation efforts and solutions

Deforestation remains a pressing global concern, requiring collective efforts to address its environmental impacts. Luckily, significant strides have been taken in the United States to combat this issue and preserve forest ecosystems, from government policies to efforts from conservation organisations. By exploring the multifaceted strategies and collaborative endeavours undertaken in the United States, we gain valuable insights into the fight against deforestation and the importance of sustainable forest management. Together, these efforts strive to safeguard our planet's invaluable forests for future generations.

Challenges and future outlook

Finding a balance between economic development and forest conservation is a complex challenge. It requires sustainable land–use practices, responsible resource extraction, and support for alternative livelihoods for communities dependent on forest resources.

Read more: What is sustainable land management?

While progress has been made, the effectiveness of conservation initiatives needs continuous evaluation and improvement. Strengthening the enforcement of regulations, addressing illegal logging, and ensuring the participation of local communities is crucial for the long-term success of deforestation-combatting efforts. Another significant challenge to the success of conservation and reforestation initiatives is funding. Studies show much more funding is needed to combat biodiversity loss and deforestation. However, global investment, especially from developed countries like the United States, is needed to meet the funding demand.

Sustainable forest management to combat the effects of deforestation and its current rates requires long-term planning, funding, ecosystem restoration, conservation, and multi-stakeholder collaboration to ensure the health and productivity of forests for future generations. 

On the future outlook side, advancements in technology such as remote sensing, data analytics, and monitoring systems provide valuable tools for assessing drivers of deforestation and deforestation rates, identifying illegal activities, and implementing targeted conservation strategies. These advancements can thus assist in monitoring, assessing, and decreasing the current rates of deforestation. 

Deforestation is a global issue that requires global action and collaboration between nations, sharing of best practices, and supporting initiatives like the United Nations' REDD+ programme (Reducing Emissions from Deforestation and Forest Degradation).

Drivers of tropical deforestation and forest regeneration in Tanzania

Forest cover change affects ecosystem services including climate and biodiversity. Global efforts to reduce deforestation, and restore forest cover, depend on understanding the rates and drivers of forest cover change. Knowledge gaps are greatest around rates and drivers of forest regeneration, and drivers of deforestation in Africa. Determinants of the rate of biomass and species accumulation in regenerating forests, are also poorly understood. Although deforestation rates have been well-studied, published rates still vary significantly, particularly in African woodlands. This thesis investigates rates and drivers of deforestation and natural forest regeneration, with a focus on Tanzania, a country with the fifth highest net deforestation, globally. Using innovative, inter-disciplinary methods, the study presents new empirical evidence on rates and drivers of forest cover change. Linking this to policy, the thesis provides new insights on the challenges of using an energy-transition policy, to reduce deforestation. New datasets show that deforestation exceeds regeneration by >0.5 Mha y-1. Tanzania’s national gross mean annual deforestation rate is calculated at 1.42% or 0.562 Mha y-1 (0.46 – 0.66 Mha y-1) (2010 – 2017). For village land, a land class that excludes protected areas, the gross mean annual deforestation rate is higher, at 1.9% or 0.608 Mha y-1 (0.46 – 0.78 Mha y-1) for the more recent period of 2011 – 2021. The gross mean annual regeneration rate on village land is far lower at 0.0132 Mha y-1 (0.004 – 0.03 Mha y-1) (1987 – 2021). New evidence is presented that agriculture causes most deforestation (81% of deforestation events), compared with only 12% attributable to charcoal. In regenerating woodlands, agricultural fallows were the most frequent regeneration driver, while biomass and species accumulation were most affected by regeneration time and precipitation. While forest and energy policies have sought to curb deforestation through an energy transition away from woodfuel, the policies have been ineffective for two reasons. Firstly, they do not address the main deforestation driver, agriculture. Secondly, they have had limited impact on charcoal consumption, with 88% of Dar es Salaam households still using charcoal in 2018. Reducing deforestation and amplifying natural regeneration both require closer inter-sectoral coordination. With most deforestation occurring on village-owned land in Tanzania, there is an urgent need for more effective strategies to enable communities to retain forest products and services critical to livelihoods.

Deforestation is the purposeful clearing of forested land. Throughout history and into modern times, forests have been razed to make space for agriculture and animal grazing, and to obtain wood for fuel, manufacturing, and construction.

Deforestation has greatly altered landscapes around the world. About 2,000 years ago, 80 percent of Western Europe was forested; today the figure is 34 percent. In North America, about half of the forests in the eastern part of the continent were cut down from the 1600s to the 1870s for timber and agriculture. China has lost great expanses of its forests over the past 4,000 years and now just over 20 percent of it is forested. Much of Earth’s farmland was once forests.

Today, the greatest amount of deforestation is occurring in tropical rainforests, aided by extensive road construction into regions that were once almost inaccessible. Building or upgrading roads into forests makes them more accessible for exploitation. Slash-and-burn agriculture is a big contributor to deforestation in the tropics. With this agricultural method, farmers burn large swaths of forest, allowing the ash to fertilize the land for crops. The land is only fertile for a few years, however, after which the farmers move on to repeat the process elsewhere. Tropical forests are also cleared to make way for logging, cattle ranching, and oil palm and rubber tree plantations.

Deforestation can result in more carbon dioxide being released into the atmosphere. That is because trees take in carbon dioxide from the air for photosynthesis , and carbon is locked chemically in their wood. When trees are burned, this carbon returns to the atmosphere as carbon dioxide . With fewer trees around to take in the carbon dioxide , this greenhouse gas accumulates in the atmosphere and accelerates global warming.

Deforestation also threatens the world’s biodiversity . Tropical forests are home to great numbers of animal and plant species. When forests are logged or burned, it can drive many of those species into extinction. Some scientists say we are already in the midst of a mass-extinction episode.

More immediately, the loss of trees from a forest can leave soil more prone to erosion . This causes the remaining plants to become more vulnerable to fire as the forest shifts from being a closed, moist environment to an open, dry one.

While deforestation can be permanent, this is not always the case. In North America, for example, forests in many areas are returning thanks to conservation efforts.
