Trees play a very important role in maintaining a good environment.

Plants play a very big role in keeping the environment good. There are different types of plants around us and from all these plants we get oxygen. So we can say that plants play a very big role in protecting the environment. 

We all have to plant trees to keep the environment good. If we all become aware and plant more trees, the environment will be much better. We will have a suitable place to live in a good environment. 

We all have to be aware and we will all join hands in cutting down trees and planting more trees. We usually get oxygen from plants. And by consuming that oxygen, we survive.
