How does deforestation affect 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.
