Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
we breathe it out, trees breathe it in
trees release oxygen that we use to breathe. the trees take in carbon wich is what we breathe out.
if we cut down all the trees we will not be able to breathe and when we breathe out the trees absorb the bad stuff and then make it clean again to breathe
trees give off carbon dioxide which is converted to oxygen, in which we need in order to breathe. the trees help us breathe!
Trees use CO2 and produce O2, allowing people to breathe.
trees
Trees are like the lungs of the planet. They breathe in carbon dioxide and breathe out oxygen. Additionally, they provide habitat for birds and other wildlife. But that's not all trees do for us!
