How does deforestation contribute to global warming

Answer: sample response : When plants photosynthesize, they remove carbon dioxide from the atmosphere. When a large number of trees are removed from an area, the levels of carbon dioxide in the atmosphere remain higher than they would be if the trees were present. Since carbon dioxide is a greenhouse gas, the presence of more carbon dioxide in the atmosphere means that more heat is trapped in the atmosphere. This causes temperatures near Earth’s surface to increase.

When forests are cleared or burnt, stored carbon is released into the atmosphere, mainly as carbon dioxide. Deforestation accounts for around 18% of all globalgreenhouse gas emissions due to human activities – this is more than global emissions from transport.
