渶娪阅渎?
I can't remember when I started collecting litter(垃圾).But it was when I got tired of seeing litter near my home and realized that no one else was going to pick it up.
I live close to a forest in Ohio,America.I can walk there in three minutes!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 it.I can't understand why people drop litter.But I will keep picking it up until they stop dropping it.
I know I can only do a small bit to help the earth,but I still think it is important.
