Today people have discovered that the nature around is getting worse and worse.2. What is threatening（威胁） the nature ?

The population of the world today is more than 6,000,000,000. That is a great number and we know it quite well. The important thing is not so much the population of the world now, but its rate of growing. It is about 1.63 percent every year after the number of dead people has been taken away. To give you some idea of birth rate, look at your watch just one minute. During that time, 259 babies were born in the world. Maybe you think that isnt many. During the next hour, over 15,540 more babies will be born on the earth. So it goes on hour after hour. How many babies will be born during the whole day ?This great growing of population will make a big problem; there will be as many as 7,000,000,000 people on the earth by the year 2010. So this is one of the biggest problems which you are going to see in your life.Choose the best answers according to the passage:( ) 1.The _ problem is very important now.A. population B. pollution C. water D. baby( ) 2. The rate of growing every year is about _ percent.A. 3 B. 1.63 C. 2010 D. 259( ) 3. About population, the important thing is _.A. itself B. its rate of growing C. dead people D. getting smaller( ) 4. How many babies will be born during the whole day ?A.259 B. 673,450 C.372,960 D.128,930( ) 5. There will be _ people by the year 2010.A. over 3 billion B. more than 7 billion C. over 30 billion D. over 70 billion iv.Population problemsTwo thousand years ago, in the year 1AD, the total number of people living on the whole earth was only 200,000,000. By the year 1650 A.D. the worlds population had increased to only 500,000,000(five hundred million).Two hundred years later, by 1850, the worlds population had doubled and grown to 1,000,000,000(one billion). Over the next one hundred fifty year period, from 1850 through 2000, the worlds population increased by six times from one billion(1,000,000,000) to six billion(6,000,000,000).China, with a population of one billion three hundred million (1,300,000,000) and India, with a population of about one billion(1,000,000,000) are the two most heavily populated countries in the world.Two of the problems facing a country with a large number of citizens are food and old people. In such countries agriculture is especially important since the farmers must grow enough food for the people. In many countries, however, young people dont want to become farmers. They want to move to big cities where there are more job opportunities and an easier lifestyle.Old people , too, can be a problem. Medical science is progressing rapidly. New discoveries are being made that enable people to live longer and longer, thus increasing the population. But as people get older and older they can no longer work. They must retire. Then ,who will take care o
