Making an Impact

Polders

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. The crash caused almost 11 million gallons of oil to spill into Alaska's water. The oil hurt 28 types of animals, plants, and marine habitats, which are still recovering today.

Hurricane Dean

A hurricane is a major tropical storm that originates in the Atlantic ocean. Hurricanes effect people by destroying their homes, making water undrinkable, and, in some cases, causing fatalities. Hurricane Dean happened in 2007 and caused 45 deaths. It effected Mexico, Belize, Dominican Republic, Haiti, Jamaica, and many more countries.

Joplin Tornado 

On May 22, 2011, a tornado caused 161 deaths and over 1,000 injuries in Joplin, Missouri. This tornado damaged almost 7,500 residential structures. These things are not uncommon for tornadoes, although the Joplin tornado was one the deadliest tornado at the time. Tornadoes are violently spinning funnels of hot and cold air that are frequent in the Great Plains, also called Tornado Alley.
