<a target="" rel="">Pollution</a>&nbsp;is the introduction of&nbsp;<a target="" rel="">harmful</a>&nbsp;materials into the&nbsp;<a target="" rel="">environment</a>. These harmful materials are called&nbsp;<a target="" rel="">pollutant</a>s. Pollutants can be natural, such as&nbsp;<a target="" rel="">volcanic ash</a>. They can also be created by human activity, such as trash or&nbsp;<a target="" rel="">runoff</a>&nbsp;produced by factories.&nbsp;Many things that are useful to people produce pollution. Cars&nbsp;<a target="" rel="">spew</a>&nbsp;pollutants from their&nbsp;<a target="" rel="">exhaust</a>&nbsp;pipes. Burning&nbsp;<a target="" rel="">coal</a>&nbsp;to create&nbsp;<a target="" rel="">electricity</a>&nbsp;pollutes the air. Industries and homes&nbsp;<a target="" rel="">generate</a>&nbsp;garbage and&nbsp;<a target="" rel="">sewage</a>&nbsp;that can pollute the land and water.&nbsp;<a target="" rel="">Pesticide</a>s—chemical&nbsp;<a target="" rel="">poison</a>s used to kill weeds and insects—<a target="" rel="">seep</a>&nbsp;into&nbsp;<a target="" rel="">waterway</a>s and harm&nbsp;<a target="" rel="">wildlife</a>. All living things—from one-celled&nbsp;<a target="" rel="">microbe</a>s to blue whales—depend on Earth’s supply of air and water. When these&nbsp;<a target="" rel="">resource</a>s are polluted, all forms of life are threatened.Pollutants damage the quality of air, water, a Pollution is a global problem. Although&nbsp;<a target="" rel="">urban area</a>s are usually more polluted than the countryside, pollution can spread to&nbsp;<a target="" rel="">remote</a>&nbsp;places where no people live. For example, pesticides and other chemicals have been found in the Antarctic&nbsp;<a target="" rel="">ice sheet</a>. In the middle of the northern Pacific Ocean, a huge collection of&nbsp;<a target="" rel="">microscopic</a>&nbsp;<a target="" rel="">plastic</a>&nbsp;particles forms what is known as the&nbsp;<a target="" rel="" title="Link: null">Great Pacific Garbage Patch</a>. Air and water&nbsp;<a target="" rel="">current</a>s carry pollution. Ocean currents and migrating fish carry&nbsp;<a target="" rel="">marine</a>&nbsp;pollutants far and wide.&nbsp;<a target="" rel="">Wind</a>s can pick up&nbsp;<a target="" rel="">radioactive</a>&nbsp;material accidentally released from a&nbsp;<a target="" rel="">nuclear reactor</a>&nbsp;and scatter it around the world.&nbsp;<a target="" rel="">Smoke</a>&nbsp;from a factory in one country drifts into another country.nd land.In the past, visitors to Big Bend National Park in the U.S. state of Texas could see 290 kilometers (180 miles) across the&nbsp;<a target="" rel="">vast</a>&nbsp;<a target="" rel="" title="Link: null">landscape</a>. Now, coal-burning&nbsp;<a target="" rel="">power plant</a>s in Texas and the neighboring state of Chihuahua, Mexico have spewed so much pollution into the air that visitors to Big Bend can sometimes see only 50 kilometers (30 miles).
