Lesson Transcript
Instructor: Kelly Beaty

Kelly has taught fifth grade language arts and adult ESL. She has a master's degree in education and a graduate certificate in TESOL.

Some of the things people do cause harm to the earth. We cause pollution when we make our water, land, and air dirty. In this lesson, you will learn what pollution is, why we have it, and what we can do about it.

What Is Pollution?

Pollution is anything that makes the earth dirty and unhealthy. Land, air, and water are all affected by pollution.

Pollution takes up space on our land. Many of the things people use every day come in packages, like food, games, school supplies, and electronics. These packages end up in large underground dumps called landfills. Landfills make land unhealthy for animals and people.

Pollution Hurts People & Animals

Pollution is in the air we breathe. Trucks, cars, and school buses leak smoky exhaust from their engines.

Water gets polluted with cleaners, paints, and chemicals. All of the pollution must be removed from our water before we can drink it.

Dumping chemicals into the ocean can hurt sea creatures. This affects human beings, too. People can get sick when they eat the poisoned fish.

Loose garbage takes away from the natural beauty of the earth. When trash is not put away, people and animals get exposed to things that could hurt them, like broken glass and harmful chemicals.

How Can We Stop Pollution?

As long as people live on the earth, there is no way to completely stop pollution. Humans use a lot of stuff! We can pollute a lot less, though.

We can give away the video games, toys, and books that we no longer use. This way they will not end up in a landfill.

Plastic, paper, glass, and other materials can sometimes be recycled or made into something else. Always look for a place to recycle something before just throwing it in the trash. If trash cannot be recycled, at least put it in a trash can instead of leaving it on the ground!
