Making an Impact


Polders are used in lowland areas to reclaim land from the sea by pumping water out. The new land is usually used for agricultural space. One well-known example is the Netherlands, which uses windmills to power the pumps that keep water out.

Acid Rain

Acid rain is caused by pollutants and chemicals being emitted into the atmosphere and mixing with the moisture in the air. The chemicals and moisture mix go back down to Earth in the form of rain water. This damages plants, animals, and even man-made structures. Some places that are greatly effected by acid rain are the Black Forest in Germany, Scandinavian Forests, Eastern North American Forests , and forests in China.

The Exxon Valdez Oil Spill

This oil spill occurred on March 24, 1989. It happened when an oil tanker crashed into a reef near Prince William Sound, Alaska.
