Earth day is all about green things. Green algae, green trees, green herbs and Lot's more. Ummm... Earth day is about recycling, reusing, and reducing are the most important things for earth. Because if you use the three R's then your just helping the earth even more which is good. I have learned a little about Earth day . All I knew was that earth day was started April 22, 1970 by Gaylord Nelson. He saw that the Earth was in great danger so he decided to do something about it. Now earth day is on the calender. I usually help the Earth at school by composing and recycling cans.We keep the cans then crush them then we give it to some person who helps with that sort of thing. Help stop litter because this is what would happen.
