Acid rain is caused by pollution. Factories, power plants and cars all release pollution. The pollution floats up into the atmosphere and it goes into clouds. The clouds build up and they rain down the pollution that was in the clouds. That is acid rain.

We can fix acid rain by buying hybrid cars. We can also ride our bikes more to reduce running our cars. We can put scrubbers in our smoke stacks. The scrubbers clean the air of the smoke so not as much pollution is going into the air. Towns with strong rivers can put turbines in the river to create electricity. There are many more ways we can help the environment.
