Tyler opened the door to his house and went inside. His mother was in the kitchen. She felt surprised when she saw his sad face. “Tyler, what happened? Is everything okay?” “Nothing is okay, Mom.” “Is there anything I can do to help?” “That’s just the thing, Mom. We can’t help. There’s nothing we can do.” Tyler kept talking,“Today, the teacher talked about Earth Day and the environment. Earth Day is a day when every person promises to do something to help take care of our world. Mrs. Green said that our world is getting dirtier and that many animals and plants are dying. She wants us to think of something we can do to help and I thought all the way home and there is nothing I can do. I can’t stop people from polluting our air and water and I can’t save all of the animals. There is not anything that I can do to make a difference.”
His mother listened and after thinking for a minute said,“Of course you can. There are lots of things you can do. For example, you can walk to school. You can use both sides of your paper to save trees. You can plant a tree every year. You can clean up rubbish from your neighborhood park. Everything you do to help the planet makes a difference. The most important thing to remember is that Earth Day should be every day!” “Oh, I see. Mom, we each can make a difference to the world. Thank you, Mom.”
