I can’t remember the date when I started collecting litter. But it was when I got tired of seeing litter near my home and realized that nobody else was going to pick it up.
I live close to a forest in Ohio, America. I can walk there within 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 made my first trip to clean the forest one afternoon. I took a big black rubbish bag with me. Ten minutes later, my bag was full of cans, bottles, broken glass and newspapers.
Since that first trip three years ago, I’ve been 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’ll 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.

A four-year-old girl is lying in the arms of a doctor. She has just become motherless. The bombing(爆炸) destroyed her home and killed her mother.
Every day we see pictures like this on TVs or in newspapers. We see young Iraqi children asking for food and water from American and soldiers as they move through towns and cities towards the capital, Baghdad(巴格达). We see these children following grown-ups, carrying bags of things almost at the same size as their small bodies as they leave their homes in Baghdad.
“Dad, why are the Americans fighting us? Are we going to be killed?” asks the son of Abu Sinar, an Iraqi engineer. Abu finds it hard to explain this war to his eight-year-old son.
He tries to comfort him by saying ,“The bombs（炸弹） are far away from us. The Americans are fighting the soldiers. We are going to be all right.” Even though Abu knows this isn’t always the truth, what else can he do? In Baghdad, parents give their children sleeping pills to make them sleep so that they won’t hear the sound of bombing. And all the schools are closed.
“All we do is to listen to and hear the war,” said Abu, “We, all the people and the children, have to live in fear(恐惧). We feel hopeless and helpless. We don’t know where the next bombs are going. We can do nothing but wait to be killed.”
