I can’t remember when I started collecting litter. But it was when I got tired of 46 litter nearby that I realized no one else was going to pick it up.
I live near a forest in Ohio, America. I can walk there 47 three minutes. I used to love going there to play with my dog. But one day there was 48 much litter there that I became very unhappy. I decided to clean up the forest, and I wanted to 49 happy when I went again. I made my first trip to clean the forest that afternoon. I took a big black rubbish bag with me. Ten minutes 50 I started to pick up litter, my bag was full! There were cans, bottles, broken glass and newspapers in it.
From then on, I 51 to the forest four times a year to pick up litter. I often stay there for three hours. It makes me feel 52 to do something for the environment. After each trip, I look through all the litter that I’ve collected. If 53 of it is recyclable（可回收利用的）, I’ll keep it. I can’t understand why people drop litter. But I will keep on picking it up 54 they stop dropping it.. I know I am only doing a small bit 55 the earth, but I still think it is important.
