The Cursed Forest
My mom told me that there was a forest near where she grew up as a little girl. She told me that you are not allowed to go there, because the land is cursed. Mom told me that a local chief's daughter was in love with the woodcutter's son. The two loved each other but the wood cutter's father wouldn't let them marry. Since firewood was their main way of living, the cheif went to the shaman who cursed the land. It would rain a posionous rain that burned the ground and so corrosive it stripped the bark from the trees. You also couldn't drink it or it would kill you, and couldn't touch it unless you wanted a nastly burn. That was the exact way my mom tried to explain acid rain to me when I was little, and how it was a huge problem where she grew up.
