A: Today, we are talking about the environmental protection. You know, there is increasing pollution that affects many facets of our life. To tell the truth, I could find only few stars last night, thats terrible.B: Yes, pollution is a big issue. When I deeply breathe the air, I am wondering if the air is clean. When I drink water, I cant help wondering if the water is clean.C: You are not alone in your worries. Sometimes, I find a pungent taste of drinking water, maybe it results from the emission of industrial wastewater, which is harmful to our bodies. Besides, there are a large number of environmental problems, ranging from global warming to ozone depletion, whose impacts will be felt around the world. Well, do you have any specific examples about this?D: Sure, For example, the influence of the rising sea level on nature. In the United States, a rise in sea level of one foot could eliminate 17%-43% of todays wetlands.A: Awful, then, what will happen when this occurs? There are lots of coastal cities will be submerged.B: Besides, that may lead to the climate change. The climate change may drive a quarter of all land animals and plants to extinction, according to the major new study published in the journal Nature.C: Can you imagine！With the knock-on effects, this complex problem can also have a severe impact on the economy and the quality of life for present and future generations.D: We cant let that happen, we should take some action. I love nature, I love the blue shy, clear water and lovely animals. To love nature is to love mankind.A: Yes, you are right. No nature, no life.D: So, lets do something. There are many things we can do, little things to make our word better! Have you ever heard of the three Rs?B: Yes. Ive heard of them! Reduce, Recycle, Reuse, is it? Reduce energy consumption, Recycle papers, plastics, bottles, glass, and reuse papers, or other materials!D: Yes, well done！C: Oh now I get it! Complicating matters is the fact that there are no obvious solutions to the problem. A plan occurred to me just now! Want to hear it?A: Of course, cant wait, what is it?C: It is actually a plan, we will make placards, and signs saying Preserve the environment! Then we can make a list of things people can do following the slogan. Stick those signs in school, let more students join us to protect the environment.B: That gives me an idea, we can go to school on foot or by bike. We can use shopping baskets not plastic bags. When we go shopping and we can use both sides of the paper when we write.C: Its a fantastic idea, I can agree with you any more. How about you, YaoYao? D: Maybe, I can recycle papers and stuffs at school and at home, By the way, I will tell all of my friends and neighbors and family members about preserving the environment.A: Fantastic! The goal of life is living in agreement with nature, but we are conducting a tremendous experiment with the planet. Its one planet, one experiment. We have no choice but to take action to preserve the planet, or we will lose our homeland forever.
