clear the rain forests.

reduce the use of wind and solar power.

Reduce the use of coal and oil. Clearing the rain forests does not help with pollution and only destroys habitats, trees, and other biotic organisms. The increase of manufacturing would only increase air pollution, as factories would release smoke into the air and harm the environment. Wind and solar power are beneficial and do not create any source of pollution, therefore C is the answer.
