Is deforestation a single factor?
There is no single factor that is responsible for deforestation. Rather, it’s a combination of forces that are devastating it.
How does deforestation affect biodiversity?
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.
How does deforestation occur in the tropics?
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.
Why do tropical forests have carbon dioxide?
That is because trees take in carbon dioxide from the air for photosynthesis, and carbon is locked chemically in their wood.
What happens when trees are burned?
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.
How does slash and burn agriculture affect the tropics?
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.
Why are forests razed?
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.

Why does deforestation matter?
Why does deforestation matter? Forests—especially tropical forests—store enormous amounts of carbon. When forests are destroyed, that carbon is released to the atmosphere, accelerating global warming. Deforestation accounts for around 10% of total heat-trapping emissions—roughly the same as the yearly emissions from 600 million cars.
Where is deforestation most prevalent?
It drives deforestation primarily in Indonesia, where forests are cut down for plantations of fast-growing tree species. Timber, used for construction or high-end products like furniture, is most clearly linked to forest degradation, in which valuable tree species are harvested and the rest remain.
How does wood cause deforestation?
Perhaps the most iconic symbol of forest destruction, wood production has been shown to cause around 380,000 hectares of deforestation annually in key countries, though the actual number is likely higher. Wood products can be divided into two categories. Pulp is made from tree fibers and used to produce paper and related products. It drives deforestation primarily in Indonesia, where forests are cut down for plantations of fast-growing tree species. Timber, used for construction or high-end products like furniture, is most clearly linked to forest degradation, in which valuable tree species are harvested and the rest remain. Degraded forests are more likely to be targeted for conversion to other land uses. Learn more >
How much carbon is in peatlands?
Peatlands contain up to 28 times as much carbon as the forests above them—carbon that's released to the atmosphere when peatlands are drained for oil palm plantations. As a result, palm oil contributes the most global warming emissions of any commodity besides beef. Learn more >.
Why is it important to change the way we produce commodities?
Because these commodities are in so many widely used consumer products, changing the way they are produced could have huge benefits for the climate , forests, and people around the world. And this change is possible—there are strategies to produce beef, soy, palm oil, and wood products in ways that allow the world’s forests to thrive.
Why are the tropics important?
With large areas of cheap land, relatively low labor costs, and a year-round growing season, the tropics have become a favored location for large-scale industrial commodity production. Eliminating emissions from commodity-driven tropical deforestation can play a huge role in reducing climate change—and we can do it in the near future.
What is the metric unit used to measure deforestation?
Talking about deforestation means talking about land area. The metric unit scientists generally use for this purpose—the hectare—may be unfamiliar to many American readers. A hectare is an area 100 meters by 100 meters, about the size of two football fields.
How does deforestation affect the environment?
Deforestation affects the people and animals where trees are cut, as well as the wider world. Some 250 million people living in forest and savannah areas depend on them for subsistence and income—many of them among the world’s rural poor. Eighty percent of Earth’s land animals and plants live in forests, and deforestation threatens species including the orangutan, Sumatran tiger, and many species of birds. Removing trees deprives the forest of portions of its canopy, which blocks the sun’s rays during the day and retains heat at night. That disruption leads to more extreme temperature swings that can be harmful to plants and animals.
How much of the world's forest has disappeared?
Forests still cover about 30 percent of the world’s land area, but they are disappearing at an alarming rate. Since 1990, the world has lost 420 million hectares or about a billion acres of forest, according to the Food and Agriculture Organization of the United Nations —mainly in Africa and South America. About 17 percent of the Amazonian rainforest has been destroyed over the past 50 years, and losses recently have been on the rise. The organization Amazon Conservation reports that destruction rose by 21 percent in 2020, a loss the size of Israel.
How many trees have been planted in Tanzania?
In Tanzania, the residents of Kokota have planted more than 2 million trees on their small island over a decade, aiming to repair previous damage. And in Brazil, conservationists are rallying in the face of ominous signals that the government may roll back forest protections.
Why do we need trees?
We need trees for a variety of reasons, not least of which is that they absorb not only the carbon dioxide that we exhale, but also the heat-trapping greenhouse gases that human activities emit. As those gases enter the atmosphere, global warming increases, a trend scientists now prefer to call climate change.
What percentage of the Earth's land animals live in forests?
Eighty percent of Earth’s land animals and plants live in forests, and deforestation threatens species including the orangutan, Sumatran tiger, and many species of birds.

Agricultural Expansion
Livestock Ranching
- Forest clearing for livestock ranching is another contributor to deforestation. Since 1990, Brazil, a top exporter of beef, has lost an area of forest that is three-fourths the size of Texas. A strong global demandfor beef, supported by governments such as in Brazil, is expanding this kind of deforestation. Solution 2: We recommend downloading the Food Monster Appon iTunes — with …
Logging
- Logging, including illegal logging, is a driver of deforestation. In Indonesia, illegal logging operations provide short-term income for people living on less than $1 a day. However, it destroys the livelihoods of those who depend on the forest. Indonesia is one of the largest exporters of timber, with about 80 percent of it being exported illegally. It is estimated that organized criminal…
Infrastructure Expansion
- Road construction can lead to deforestation by providing an entryway to previously remote land. The 5,404-km Interoceanic Highway, which runs from Brazil to Peru, is a concern for conservationists as the road cuts a strip through the biodiverse Amazon rainforest. The road expansions often lead to logging and illegal logging, where opportunists slash down trees withou…
Overpopulation
- Our planet once housed an estimated maximum of 15 million people in prehistory. It now sustains a whopping 7 billion and counting. With overpopulation, there is an increase in global needs and wants, leading to expansion and deforestation. The planet’s forests are being devastated at an even ratewith population growth.
