Answer:
For every tree cut down, replant two trees
Replanting two trees for every tree cut down decreases air pollution to 338 ppm
Step-by-step explanation:
Replanting two trees for every tree cut down decreases air pollution to 338 ppm
Creating more protected areas decreases air pollution to 368 ppm
Limiting the amount of timber that can be removed per year decreases air pollution to 378 ppm
The number of ppm is less so my answer is correct. I know this because I did this assignment.
