explain why deforestation can contribute to global warming?

When trees are cut down and burned or allowed to rot, their stored carbon is released into the air as carbon dioxide. And this is how deforestation and forest degradation contribute to global warming.

Tropical forest trees, like all green plants, take in carbon dioxide and release oxygen during photosynthesis. ... When trees are cut down and burned or allowed to rot, their stored carbon is released into the air as carbon dioxide. And this is how deforestation and forest degradation contribute to global warming.

Deforestation is a global issue. Despite their immense value, nearly half of the world's forests have been lost. ... Therefore, deforestation is a global issue. When forests are cleared, they emit carbon dioxide back into the atmosphere and put humanity on a dangerous collision course with the worst of climate change.

And this is how deforestation and forest degradation contribute to global warming. According to the best current estimate, deforestation is responsible for about 10 percent of all global warming emissions.

There are many problems that result from this method of growing crops, including deforestation, a direct consequence of cutting down forests for crop land; loss of habitat and species; an increase in air pollution and the release of carbon into the atmosphere—which contributes to global climate change; and an increase ...

Deforestation is usually caused by slash and burn agricultural practices or from logging by the timber industry. Destroying trees can directly harm animals that may have built nests there, or by changing microclimates. Animals that heavily rely on trees may be unable to adapt to a new habitat.

Loss of forests means loss of species: Forests are home to seventy percent of the world's plants and animals. Deforestation contributes to global warming: About 20 percent of the world's greenhouse gas emissions come from the clearing of tropical forests.

Deforestation can cause a domino effect on the whole planet, including global climate change, indigenous people annihilation and biodiversity extinction. One wrong move, and the process will lead us to an empty and meaningless world. The death of plants and animals can lead to a partial loss of human life.

Because of deforestation and forest fires, soils lose their vegetation cover. The erosion process is thus accelerated, creating soil degradation as well as water pollution. Deforestation leads to the loss of the land's value as, once converted into a dry or barren land, it can never be made fertile again.

Other devastating effects of deforestation include soil erosion, an increase in the greenhouse gases leading to global warming, loss of biodiversity, increased flooding, and drought.

In terms of climate change, cutting trees both adds carbon dioxide to the air and removes the ability to absorb existing carbon dioxide. If tropical deforestation were a country, according to the World Resources Institute, it would rank third in carbon dioxide-equivalent emissions, behind China and the U.S.

The forest also absorbs carbon dioxide, including from sources like pollution. Losing a significant part of the forest woud speed up climate change because more carbon dioxide would be in the atmosphere, experts say.

Deforestation has a direct link to soil erosion. And like fingers, they grip the soil they penetrate. This makes the soil immune to getting washed away during rains, heavy winds or floods. Forests actively prevent soil erosion, which has been considered the biggest caused of land degradation.

Trees remove CO2 from the atmosphere when they photosynthesise, so without them less CO2 is removed. So deforestation means more CO2 in the atmosphere which leads to global warming. ... Without trees, the water isn't removed from the soil and evaporated into the atmosphere.

Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. ... Deforestation results in fewer trees to absorb the gas. Also, when plants are cut down and burnt or left to rot, the carbon that makes up their organic tissue is released as carbon dioxide.
