Answer 2

Heya!

Trees are important for us. Aren't they? They are indeed. According to your question, the answer is-:

• A is OXYGEN. Plants give oxygen. If the trees will be cut down , the life gas that is oxygen will decrease and that will have a dangerous impact.

•B is CARBON DIAOXIDE. Plants take in the carbon dioxide we give out. If tress will be cut, carbon dioxide won't be taken in by anyone, and thus increase in carbon dioxide will be there and it's dangerous.

•C is global warming. Carbon dioxide will make the earth heat up and that will make an undesirable impact on the surrounding.
