So i have a question that says What is the pH of acid rain and i got the answer to that (using science book) but it wants me to tell why it is important (for a weathering paper)

For living organisms to live.

Explanation:

There are level restrictions for acid and alkali. Acid's level shouldn't be too high since it might damage the environment by polluting the waters, and polluting the soil, which we grow crops in. The crops might be dangerous and poisonous to eat.
