 I like to take a walk on a pretty day. I like to look at trees and plants. I like to look for animals too. Today I'm going on a different walk ——a trash walk. Do you want to join me? Let's go. I'll get the trash bags. You get the gloves. As we walk we can look at trees,plants and animals. On this walk we'll look for trash,too. When we see it,we'll pick it up. This will help the Earth.

  Trash is not good for our planet. When the wind blows trash into rivers and streams,it hurts the animals that live there. It pollutes the water. Trash can harm wildlife on land,too. Animals try to eat it. This can make them sick. Picking up trash helps our planet in other ways,too. It helps it look better!Most people like to look at plants and flowers,but no one likes to look at trash ！

  Let's have a competition. We'll see who can pick up the most trash. This competition will have lots of winners. The person with the most trash will win. So will the people who get to enjoy nature without seeing lots of trash. The biggest winner,I think,will be the Earth. Ready? Set? Let's go on a garbage walk ！
