Most of the time, I shoot out of smokestacks when power plants burn coal to make electricity. I think it's cool to make it hard for some people to breathe. And I can make trees and other plants grow more slowly. Acid rain is a big problem. It can hurt or kill fish and other animals that live in lakes and rivers and some scientists think it makes trees sick.
Acid rain can even eat away at statues and buildings.
Hey, I can even travel a long way to do my dirty work. Just call us the Nitros for short. Hey, I didn't know pollutants could spell. Very funny, Harry. We get airborne when cars, planes, trucks and power plants burn fuel.
