eliminates air pollution saves nonrenewable energy reduces the amount of oxygen in the air keeps the habitats of animals from being destroyed
I gave my students this multiple choice question: Recycling paper reduces the number of trees cut down for paper production. How does this reduction most likely benefit the environment?

Only one answer is correct among these 4 choices:
- eliminates air pollution
- saves nonrenewable energy
- reduces the amount of oxygen in the air
- keeps the habitats of animals from being destroyed

Could you tell me which one is correct?

keeps the habitats of animals from being destroyed
