How did I become known as a "rubbish picker '? I never 36 rubbish before. I didn't care where it went or who cleaned it up. But two years ago, I started caring about it deeply. I lived near a forest in Ohio, America. I can walk there 37 three minutes! I used to love going there to play with my dog. One day there was 38 much rubbish there that I became very unhappy. I decided to clean up the forest. I want to 39 happy going there again. I made my first trip to clean the forest that afternoon. I took a big black rubbish bag with me. Ten minutes 40 I started to pick up rubbish, my bag was full! From then on, I go to the forest four times a year 41 rubbish, it makes me feel 42 to do something for the environment. After each trip, I look at all the rubbish that I've found. If 43 of it is recyclable, I keep it. I will keep picking up 44---people stop dropping it. I know I am only doing a small bit 45 the earth, but I think it is important.
