This is a story from a meeting held by some people and two things in nature. We call it the Four-Sided Talk. Let’s “listen to” everyone carefully and find out what they think.

People: “We have lived on the earth since ancient times. The earth is our home. Now we regret what we have done to our home! ”

People

The earth belongs to all of us. From now on,we should not only make full use of the resources(资源)on the earth,but also beautify and protect the earth. Let’s try our best!

The United Nations

We only know a little bit about the environmental problems. Hearing what all of you said,we have made up our minds to protect the earth and love the earth. We have also made the June 5 th World Environment Day. 

An Old Tree

I am thousands of years old,but I have fewer and fewer friends. I’m afraid that soon I will be cut. People cut down many trees to make paper and chopsticks. They destroy the forests and the natural environment. Now there are no trees to make oxygen and to protect people from floods. Mother nature is making many disasters to teach people a lesson.

The River

What the old tree said is right. I not only make the earth more beautiful,but also provide the clean water for people and animals to drink. Now I’m sad because people put waste and garbage into us,which kills many animals and plants that drink our water. People drink this kind of water and get sick,too.

 All our food comes from the soil. Some of us eat meat,but most animals live on plants. If there are no plants,we should have no animals and meat. So the soil is necessary for life.

 The top of the ground is usually covered with grass or other plants. Plants grow in soil,which has a dark color. This dark soil is humus. Dead leaves,dead plants and animal waste make it,but this takes a long time. When the humus has been made,plants can grow well in it.

 All soil needs food. If we don’t give it any,the plants will be weak. Animal waste is the best food for the soil,but chemical fertilizers are also very useful. The same crop should not be grown in the same place every year,and it is better to have a different crop. A change of crop and the use of a good fertilizer will keep the land in good condition.

 When the soil is dry,the wind blows it away. Sometimes heavy rain carries the humus down to the river. People should grow more and more trees and grass to stop wind from carrying the humus away. It takes hundreds of years to make humus,so we must save every bit of it. Without soil,where can we grow food?
