Mercury Pollution

Coal naturally has traces of mercury in it. Half of mercury emissions come from power plants, but installing pollution control devices can prevent this.

Effects of Air Pollution

Air pollution is one of the most obvious forms of pollution in our environment.

Causes of Air Pollution

In large car-dependent cities, up to 85% of air pollution can come from car emissions.

Types of Air Pollution

Remember that primary pollutants affect the atmosphere directly, and secondary pollutants always involve chemical reactions before going into the atmosphere.

Air Quality

Earth Science Concepts dealing with weather explain how wind, mountainous regions, and temperature inversions affect clouds. Think about how these factors can apply to pollution as well.

Oil Spills

Oil spills can release hundreds of millions of gallons of oil into the ocean at one time.

Ocean Garbage Patch

The largest collection of trash is in the Pacific Ocean, called the Pacific Ocean Garbage Patch.

Coastal Pollution

Dead zones can span hundreds or even thousands of kilometers of ocean at a time.

Conserving Water

Think of saving water as saving money. There is only a finite supply, so spending it sparingly can extend the time you have water (money) so you can spend it when you need to.

Cleaning Up Groundwater

Consider the process of cleaning up groundwater. Do you think it is worth it to clean up groundwater?
