IF we cut trees what will happen?

Answer 1

CO2 levels increases

no free air

more air pollution

Answer 2

Answer:

Trees give out oxygen, even because of them we have the rains, in short they maintain the ecological balance. If we would cut trees what is going to happen is that population won't stop growing but oxygen in the atmosphere will reduce. ... They breathe in carbon dioxide and breathe out oxygen.

If there were no trees I couldn't have gave answer of this question and you wouldn't have asked the question.
