Why is the rainforest important?

Two parts  of the rainforest are the floor and the canopy.

The rainforest is very good for the planet because the sun shines then the tree sweats a lot  when the sweat  rises up to the cold air then it makes clouds and rains.

And here is the science bit. They listened intently to the way trees provide us with oxygen to breathe and how trees can even breathe, eat and drink through their roots.
