    How green are you? Do you know how to be green?

    We all need a healthy environment, but we produce waste every day and it is harmful to our environment. Though we are young, we can still do something to help. Here are some ideas for you.

    Reduce

    "Reduce" means "use less". Don't waste things. This saves money and reduces pollution. Before we buy something new, think whether it is really necessary 一 or maybe the old one is still useful.

    Reuse

    "Reuse" means "use again". When we buy things, make sure that they can last a long time. When something is broken, we should repair it instead of throwing it away and buying a new one. Don't use a paper cup or a paper bag. It's better to use a china cup and a lunch box because you can use them again.

    Recycle

    "Recycle" means "change things into something else". Though it takes energy to change something into something else, it's better than throwing things away or burning them.

    So please remember these words: reduce, reuse and recycle.

    This is a story from a meeting held by some people and two things in nature. We call it the Four 一 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! The earth belongs to all of us. From now on, we should not only make full use of the resources 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 June 5th 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 air 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.

    Hundreds of years ago, life was much harder than it is today. People didn't have modern machines. There were no modern machines either.

    One of the biggest ones is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and affects our drinking water. Noise pollution makes us talk louder and louder. Air pollution is the most serious kind of pollution.

Cars, planes and factories all pollute our air every day. Sometimes the pollution is so thick that it is like a quilt over a city. This kind of quilt is called smog.

    Factories must now clean their water before it is thrown away;

they mustn't blow dirty smoke into the air.

    We need to do many other things. We can put waste things in the dustbin (垃圾箱) but can't throw them on the ground. We can go to work by bus or with our friends in the same car. Laws are not enough. Every person must help to fight against pollution.

A: Would you like to help protect the environment?

B: Certainly. What can I do?

A: Well.

B: Yes. I'll remember that. What's next?

A: Second, you can ride a bike.

B: That will save money too. What else?

A:

B: Mmm, newspapers, magazines, books ... We have got a lot of paper at home.

A: That's right.

B: OK. My parents do most of the shopping. I'll tell them.

A: Let me see. Oh, you can take short showers.
