Question
How does deforestation lead to global warming?
✓
Answer
Deforestation leads to global warming. When trees are there, during the process of photosynthesis, the carbon dioxide ($CO2$) is used and oxygen is give out. When there are more and more no trees they use more carbon dioxide and give out oxygen and bring more rainfall. However when the number of trees are few, the amount of carbon dioxide is increased. Carbon dioxide causes greenhouse effect and global warming. The reduce rainfall also increases the temperature and causes global warming.
