I can’t remember when I started collecting litter．But it was when I got tired of   1   litter nearby and realized that no one else was going to pick it up．

I lived near a forest in Ohio, America．I can walk there   2   three minutes! I used to love going there to play with my dog．But one day there was   3   much litter there that I became very unhappy．I decided I had to clean up the forest, and I wanted to   4   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   5   starting to pick up litter, my bag was full! There were cans, bottles, broken glass and newspapers in it．

From then on, I   6   to the forest four times a year to pick up litter．I’m often there for three hours．It makes me feel   7   to do something for the environment．After each trip, I look at all the litter that I’ve found．If   8   of it is recyclable, I keep it．I can’t understand why people drop litter．But I will keep picking it up  9   they stop dropping it．I know I’m only doing a small bit   10   the earth, but I still think it’s important．
