what solution can you create to stop or limit the effects of acid rain?
First, I would look at how acid rain is created. It is created when NOx and SOx combine with water in the air, which lowers the PH of the water, and then falls as acid precipitation. So the best way to limit the effects of acid rain would be to prevent it from forming. Therefore, find things that emit NOx and SOx (coal burning power plants emit a lot!) and try to find ways to regulate or limit those emissions.
