D. it could decrease the amount of carbon dioxide available to the forest

A.

Explanation:

When a power plant is made they all have these pies that come out of the buildings to extract the smoke but what most people don't know is that smoke is put out in the air and is taken to the clouds which mixes with the rain and since it is toxic it eventually leads it to be acid rain the more smog it picks up. Acid rain is very dangerous it burn down a whole forest, so yes, your answer is A.
