Turtle's Diary

June 15

Dear Diary,

I'm swimming in the lake. There are some fish below me and above me. My turtle friends are sitting on stones in the sun. There are people having a picnic near the lake. Oh, no, they're littering!

Dear Diary,

I'm in the lake again today. What's that I see below me? Fish? No. I see cartons and plastic bags. It's trash from the picnic! Oh, no! A plastic bag is around my leg. It's hard to swim, so I climb up on a rock.

Dear Diary,

This plastic is still on my leg. I'm sad because I can't go in the water. Look! It's a man in a boat. He rescues me. Please don't litter! It's bad for all living things.
