I used to love going there to play with my dog.But one day there was so much litter there that I became very unhappy.I decided to clean up the forest.I wanted to feel 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 after starting to pick up litter, my bag was full! It had cans, bottles, broken glass and newspapers in it.Since that first trip three years ago, I've gone to the forest four times a year to pick up litter.I'm often there for three hours, It makes me feel great to do something for the environment.After each trip, I look at all the litter I've found.If any of it is recyclable(可回收的) I keep.
