Planting more trees is good for the environment.

Planting more and more trees is very good for our environment, so we all have to be aware and plant more and more trees. If we all become aware and if everyone starts planting trees more or less, then our environment will become more beautiful. 

We usually get oxygen from trees. And by taking that oxygen, we sustain life. So trees play a very big role in our survival. Besides, trees maintain the balance of the environment by taking carbon dioxide from the air.
