What is Deforestation?
Deforestation can be described as the decline in the number of forests areas across the world. The implementation of cutting down trees and using the land for purposes other than the planting of trees is called deforestation.
Causes of Deforestation
Deforestation has been happening for thousands of years, since man began converting from hunter/gatherer and started establishing agriculturally based societies, and required larger amounts of land to accommodate cattle, crops, and housing. Deforestation is caused due to a number of reasons, including farming, industrial purposes, etc.

How do forests affect the environment?
Forests have a big influence on rainfall patterns, water and soil quality and flood prevention too. Millions of people rely directly on forests as their home or for making a living. But the risks from deforestation go even wider. Trees absorb and store carbon dioxide. If forests are cleared, or even disturbed, they release carbon dioxide and other ...
What happens if forests are cleared?
If forests are cleared, or even disturbed, they release carbon dioxide and other greenhouse gases. Forest loss and damage is the cause of around 10% of global warming. There’s simply no way we can fight the climate crisis if we don’t stop deforestation. We need to protect forests now more than ever.

Why forests matter. As well as being stunningly beautiful, forests are vital for the health of our planet. They provide food and shelter for so much of life on Earth – from fungi and insects to tigers and elephants.
How many trees are being cut down in a year?
And the fastest rate of forest destruction has been in the past couple of centuries. Up to 15 billion trees are now being cut down every year across the world.
Air pollution
As part of their metabolism, the plants absorb carbon dioxide and give off oxygen , ie perform the opposite process that animals . In this way, forests oxygenate the air and at the same time remove carbon dioxide , which is toxic.
Desertification
Due to deforestation, the soil loses its nutrients and becomes infertile.
Difference with forest degradation
Forest degradation is the reduction or destruction of some specific aspects of the forest , but not the forest as a whole.
Deforestation for agriculture
Due to the erosion of the soil, deforestation for agriculture is limited in time.
Industrial deforestation
Sweden has managed to curb industrial deforestation with forestry laws.
Deforestation by urbanization
Deforestation due to urbanization occurs in countries with high population density.
Involuntary deforestation
In addition to human action, forests are also threatened by natural causes. The most frequent cause of involuntary deforestation is fire . However, many unintentional fires are caused by the carelessness of man.
Why is deforestation important in tropical rainforests?
Deforestation is a particular concern in tropical rain forests because these forests are home to much of the world’s biodiversity. For example, in the Amazon around 17% of the forest has been lost in the last 50 years, mostly due to forest conversion for cattle ranching.
Why is deforestation happening?
Expanding agriculture, due to an increased population and shifts in diet, is responsible for most of the world's deforestation. As the human population continues to grow, there is an obvious need for more food. In addition, agricultural products, such as soy and palm oil, are used in an ever-increasing list of products, from animal feed to lipstick and biofuels. Rising demand has created incentives to convert forests to farmland and ranch land. Once a forest is lost to agriculture, it is usually gone forever—along with many of the plants and animals that once lived there.
What are the threats to the tropics?
The threats manifest themselves in the form of deforestation and forest degradation. The main cause of deforestation is agriculture (poorly planned infrastructure is emerging as a big threat too) and the main cause of forest degradation is illegal logging. In 2019, the tropics lost close to 30 soccer fields' worth of trees every single minute.
What are the effects of deforestation on the Mekong?
In the Greater Mekong in Southeast Asia, where land tenure systems are weak, deforestation has contributed to social conflict and migration. In Brazil, poor people have been lured from their villages to remote soy plantations where they may be abused and forced, at gunpoint, to work under inhumane conditions.

How does deforestation affect the human population?
According to the Institute of Research for the Development (IRD), forests diminish infectious diseases. The deforestation remains one of the main causes of the emergence of new infectious agents and their epidemic movement in the human populations. According to a study, 40% of the world population lives in regions affected by malaria. Yet, in the areas zones highly deforested, the risk of contracting this disease is 300 higher than in the forest areas.
How does deforestation affect soil?
Deforestation weakens soils. The forest makes soils richer in terms of organic matter and makes them more resistant to bad weathers and erosions. Thus, when a forest is destroyed, the soil is weakened and becomes more vulnerable to natural disasters (landslip).
How much of the world is covered in forests?

What is the biggest threat to biodiversity?
The forest shelters mammals, birds, insects, amphibians and species often rare and fragile. Deforestation is thus a disaster not only for Men but also for all lives on Earth. One of the biggest dangers : the biodiversity loss can be irreversible. Many species are threatened with extinction because of forests disappearance. For example, the bigs apes in Africa, see their number tremendously diminish because of the destruction of their natural habitat.
What is deforestation in the forest?
Deforestation is the phenomenon of forest areas reduction. We talk about deforestation when forest areas are definitely lost for uses such as agriculture, urbanization or mining activities. Our foundation Free Spirit wants to raise awareness of massive deforestation.
Why are forests important?
Forests are essential to the structure and the soil quality. Indeed, they diminish the hydric and wind turbine erosion and maintain the cycle of nutrients in these soils. A bared soil does not bring the essential protection anymore against violent rains. Environment becomes then more favorable to landslide and flooding. Haïti for example, where more than 90% of trees were cut down, keeps suffering from deadly mudslides because water is not kept anymore by the roots in the localities localized on sea level. In others regions of the world, particularly affected by deforestation and where hurricanes commonly happen, forests are not natural barriers anymore to protect against tsunamis and cyclones.
Is palm oil a cause of deforestation?
Palm oil production, more and more reported, is one of the most important causes of deforestation in some regions of the world. According to the FAO, palm oil industry has been a huge factor in deforestation. Thanks to the pressure of some NGOs, of new regulations and consumers, the palm oil sector begins to be normalized after having known a huge number of illegal forest exploitations. This industry can be also a real environmental problem.
