I read that 38 top scientists meeting in Denmark said we should forget about global warming. W: Yes, they said global warming is important, but there are other problems we should solve like AIDS, hunger, and Malaria. First things first is their theme. Q: What do some of the top scientists think about global warming? Question 2 M: Its suicide! Were killing ourselves with acid rain. Smoke from burnt coal mixes with sunlight to create poisonous sulfuric acid that destroys plants, animals and people like us. W: Hold on! What youve said is true, but governments everywhere are punishing polluters and encouraging alternate energy sources like solar power and wind power. Things are looking up. Q: What is the womans point of view? Question 3 W: Water pollution in my home town is very serious. I think its high time that the government take some measures to tackle the problem before its too late. M: I think Im gonna make your eyes green with envy if I tell you that the water in my home town is well conserved. Q: What can we learn from the dialog? Question 4 W: John, are you interested in joining in our club to raise money for the protection of wild birds in the States? M: Why not? I learnt from an article the other day that the wildlife in our country is diminishing. Ill certainly do my part. Its really sad if we can only see wild birds in zoos. Q: What is the man going to do? Question 5 W: Mark, did you hear about black pollution? I know that white pollution refers to plastic pollution. Is black pollution related to coal or air exhausted by factories? M: No, honey. Its the pollution by the waste rubber. Its a serious problem in our country. Q: What causes black pollution? ScriptEvery day, the average person breathes in about 20,000 liters of air.Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air. Air pollution includes all pollutants found in the atmosphere.These dangerous substances can be either in the form of gases or particles. Air pollution can be found both outdoors and indoors.Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time. The sources of air pollution are both natural and human-based.As one might expect, humans have been producing increasing amounts of pollution as time has progressed, and they now account for the majority of pollutants released into the air. Air pollution has been a problem throughout history.Even in Ancient Rome people complained about smoke put into the atmosphere. The effects of air pollution are diverse and numerous.Air pollution can have serious consequences for the health of human beings, and severely affects the natural ecosystem. Because it is located in the atmosphere, air pollution is able to travel easily.As a result, air pollution is a global problem and has been the subject of global cooperation and conflict. Some areas now suffer more than others from air pollution.Cities with large numbers of automobiles or those that use great quantities of coal often suffer most severely from air pollution problems.ScriptThe panda is found only in the western mountains of China.
