LONG ANSWER QUESTIONS
21. Is deforestation associated with global warming ? Explain.
Answers
Tropical forest trees, like all green plants, take in carbon dioxide and release oxygen during photosynthesis. Plants also carry out the opposite process—known as respiration—in which they emit carbon dioxide, but generally in smaller amounts than they take in during photosynthesis. The surplus carbon is stored in the plant, 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. According to the best current estimate, deforestation is responsible for about 10 percent of all global warming emissions.
The disadvantages to deforestation are an increased amount of carbon dioxide emissions and soil erosion as well as the destruction of forest habitat and the loss of biological diversity of both plants and animals.
