Pollution: Can Be a Product of Useful Acts.(Brief Article)
The acid rain that destroyed the trees in the photograph resulted from a very useful action many miles away. There, coal was burned to produce steam to turn turbines that generate electricity for tens of thousands of people. Among the products released into the air when the coal burned were gases containing sulfur and nitrogen. These gases combined with the oxygen and water vapor in the air and formed droplets of acid. In time, the acid droplets came down in the rain that fell, creating the destruction you see in the photo.
Sometimes, people construct housing developments or factories in areas where the natural barriers between freshwater and saltwater habitats are disturbed. When that happens, two otherwise unpolluted bodies of water may mix to form a polluted third body.
