How to protect the environment

The environment in my city is becoming worse.

Look! My father is taking （photo） for us. And my mother is lying （躺着）the beach. Where is my sister? Oh, she is （swim）with other girls in the sea. I am playing football on the beach. It's very  （interest）. I really have  great time here.

World Sleep Day is on March 21. Many people in the world don't have good sleep.

Zhao Min doesn't sleep well these days. When she sleeps, Maybe she has too much pressure （压力） because of her job. It is bad for her health.

Here is some advice （建议） about sleeping .

◆ Some doctors think you can relax by listening to music or exercising after work.

◆ It helps people a lot . When you sleep, It also helps you to sleep well.

◆ If there is too much noise near your house some day, you can sleep in a hotel or a friend ' s home .

More than 50, 000, 000 people live in the rainforests （热带雨林） of the world. When we cut down the rainforests , we destroy （摧毁） the home of the people living there too. In 1900, there were 1, 000, 000 people living in the Amazon forest. In 1980, there were only 200, 000.

The Yanomami live in the north of Brazil. They have lived in the rainforest for about 10, 000 years and they use more than 2, 000 different plants for food and medicine （药）. But in 1988, someone found gold （金子） in their forest , and suddenly 45, 000 people came to the forest and began looking for gold. They cut down the forest to make roads. They made more than a hundred airports. The Yanomami people lost land and food. Many died because new diseases （疾病） came to the forest with the strangers （陌生人）.

In Borneo, people were cutting down the forest to sell the wood. The Penan people tried to save their rainforest. They made blockades （障碍） across the roads into the forest. In 1987, they closed fifteen roads for eight months. No one cut down any trees during that time. In Panama, the Kuna people saved their forest. They made a forest park and visitors pay to visit it. The Gavioes people of Brazil use the forest, but they protect it as well. They find and sell the Brazil nuts which grow on the forest trees.

The Earth is about 4, 600 million years old. Man lives on the Earth for only 35, 000 years. But we change our Earth in many ways. Many things we do are good, but some are not good for the Earth.

Water pollution

A lot of people, binds and fishes die each day because of water pollution. Factories pollute the water. As a result, the water in many rivers and lakes is now very dirt.

Air pollution

In big cities, factories, cars and buses are the main causes of air pollution. Many people in cities now have health problems. For example, Mexico City used to be a beautiful sunny capital, but today there are many dark clouds in the sky. And many people get ill because of the polluted air.

Soil （土壤） pollution

In order to have a better harvest, some of the farmers use chemicals too much in their field. That's bad for the soil.

Hope for the future

These problems are very serious for our future, so all of us should do something to protect the environment. If we can stop pollution, our earth will become more and more beautiful.
