Why Is Cutting Down Trees Bad?

Learning Intention: I am learning to write a persuasive text using information to persuade readers my point of view is right.

I believe cutting down trees is so bad because we will have no oxygen to breathe. People destroy the animals and birds' home.They will become extinct. Some of the birds will migrate to another country.The cave men will not have food and shelter. Also cutting down trees causes erosion. The soil will get washed away. We will get sunburn because we will have no shade. 
I believe that cutting down trees should not be allowed.
