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.

My grandfather is eighty years old. He sometimes complains（抱怨）about how fast things have changed.
He often says that families aren’t the families they used to be. A lot of families have broken up（破裂）. If husband and wife have problems with their marriage, they will no longer stay together. And mothers used to stay at home to take care of their children, but now they’re busy working. They have no time to look after children at home. What’s more, more and more people drive. We used to walk five miles to school every day, even in winter. But now children don’t. And in school, children don’t have to think more as we used to. In math class, for example, we used to add, subtract, multiply and divide（加、减、乘、除）using our heads. But now most students use calculators. Most families have computers now. In the past, we didn’t have computers. We even had no lights. My mother to spend all day cooking in the kitchen. But now few people eat home-cooked food. And people seldom talk to each other. They are too busy to talk, too busy to eat, too busy to think… Life used to be simple, but it isn’t any more.
