23 billion tons,can you image how big is this number. If there are 23 billion tons of water, it is quite easy to cover all the land of Japan by the 3M high water. Also, depend on the estimate of New York City Department Of Transportation the weight of Empire State Building is 365000 tons. (6) So 23 billion tons are equal to 630,137 Empire State Building, and this is also how much carbon dioxide people will make and into the atmosphere every year. Image that once you look up, you could see thousands of enormous building float on your head, Don’t you shock? And this is the reason why the global warming will become more seriously today.
When we are talking about the global warming, a reason why it happens is important for us to know. In recent years, the dramatic increase of wordily population is one of the main factors cast global warming. Also, that can be classified to one of Human factors. The carbon dioxide which people made each year will become unbelievable Numbers if we compare it with the statistic of pastime. (1) Now, the global emissions of carbon dioxide get into the atmosphere every year is about 23 billion tons, compare with early 20th century are 20% more than that time, and it still increasing at an of 0.5% of the amount each year. (2) And those carbon dioxides will stay in the atmosphere direct and unceasingly increase, then with tie goes by, it can cast the "greenhouse effect" became more serious. Except that, there are another two Human factors. Atmospheric environmental pollution factors are the other serious environmental pollution has constituted as a major problem cast the global warming, In addition, Marine ecological environment deterioration factors also is one reason we can not ignore it. Even some industrial waste is not allowed to be discharged into the ocean directly, but sometimes we still can hear some news about land has produced large amounts of toxic chemical waste and solid waste constantly into be discharged the sea. (3)According to researcher predict that next century, sea level could rise 50 cm ever year because of dangerous synthetic waste can cast the iceberg melting. In the next 50-100 years, human will completely get into a warming world. (3)”In the next 100 years, the temperature of the east Asia and China will have a dramatic increase, the global average ground surface well.” temperature will rise 1.4 ℃ to 5.8 ℃.To 2050, the average temperatures would rise by 2.2 ℃.(4)since that main problem cast by that is Glaciers are melting, and sea levels will rise. When the temperatures rise, sea lever as will as rise. And there are a bunch of serious environment problems is coming flower it. “sea-beach wetland, mangroves and coral reefs and other ecological group live by the water will lose.” (4) Water area on the Earth will increase. A rainy season is coming since it cast more evaporation of the water, floods are becoming more and more frequently. It is possible for floods to happen. More storms will have happened in future, the reservoir’s lifespan is going to shorten. (1) Rising temperatures also could make the Antarctic peninsula and the ice and snow in the arctic sea melting. The polar bear and walrus will be extinct. (4) (7)Another study about global warming show that in northwest Europe, a local temperature may drop 5-8 ℃ during next 70 years, Earth might need to face a new ice age! The arctic ice has melted, rainfall is increases just like what I mention before, and mind type has changed. Depend on that factor a large number of fresh water had flowed into the north Atlantic when the global warming happened, disturbed the Gulf Stream and cut off the warm currents in the north Atlantic. Thanks to warm currents can not arrive at the northwest Europe a chain reaction was started. All the ocean currents will change. All warm currents go to the one side of the Earth, and all cold current will assemble to another side. The consequence of it is extreme weather will appear more often, some places in the earth will extreme cold and some places will become extremely hot, science that the species chain, the food chain has destroyed little by little. And that could let human lost more than 10,000 type of species during the next 100 Years.(7) Global warming is a word which almost everyone knows, but it is hard for people to imagine how severity and terrible its consequence will be. Natural ecosystem balance and human food supply will thoroughgoing cut off if we do not focus on environmental management and protection.

When I was walking on the street with my friends, we saw several people was fighting. I was interested about that so I want to come close to watch, but one of my friends told me: “let sleeping dogs lie.” Then we left there. Next day we saw a news about the fight we had seen yesterday set off a gunplay, 5 people had been killed by that.
Can you imagine that a country that a government disagreed with young people going to school? Also if you are a teacher, you will be punished by your student? Does it make your feeling horrible? Maybe people who read to here considered they will never go to this country. But what I want to say is, I am born in this country delete; she is my motherland. Also, I believe I get enough education from her which makes me at least able to study abroad. Yes, this country is China. Why can I find severe extremely differences even when I am talking about the seam same country? Because the first part I am contract describing China 50 years ago, the other part what China truly looks like now. I will introduce what is different now in China than 50 years ago in several ways: Healthy, education, and job. Chinese People usually live longer than before. In only 50 years Chinese life expectancy has increased from “36 years old”. The average life of Chinese is 71 years old now, but back to 50 years ago it was only 35 years old. (1) Also now Chinese life expectancy is already up to 71 years old. (4) Also, the other reason to support that point is as time goes by now China has more than 310000 medical institutions which can serve people. But do you know how many medical institutions China had 50 years ago? Only 3670 medical institutions disperse. (1) this is an a superior increase of a delete developing country. I can say that If I had been born in 1960, I absolutely would have worried about whether I would have been injured and would not have been able to find a cure. We are much better at preventing disease than in the past. China now has delete health care for almost all people, but that was impossible for China in the past. Zhanlian Feng (2) points out that MP from the 1950s to 1980s China almost did not have any form of health care Citizens even didn’t know what health care is Also, Zhanlian Feng (2) shows that another problem for Chinese at that time was people who needed medical care usually needed to take a long walk to the main city. In 1994, in 160 villages more than 8399 people ha that problem. Today China is able to make medicine unlike before when it depended depending on imports. The number of the hospitals has a huge achievement increase from 67 to the 350,000,0 around China. (2) Another main change that happened in China is the economy became much better. In the < China Economic Review>(3) “China’s agriculture value is 139.7 billion yuan in 1978” 30years later the value of agriculture became has 653.38 Billion yuan. From these numbers of the data with it is not hard to find China has a great improvement in agriculture. In the 1998, China's industrial output has accounted accounted for 75% of the gross value of industrial and agricultural output; the gross industrial output value is 3 times of agricultural output. < China Economic Review>(3) had pointed that out. That means delete China has been started has started to develop the manufacturing and had has had a great achievement from it. China in 1988 reached the level of 660 million tons of grain, while India's food production in 2009 was only 220 million tons per year. Another way to show Chinese economic has been improving is GD.(3) In1974 (1970s OR 1974?) the GDP of China CAP was $142.225 billion; that look like it is kind of high, but back to that time China already had 900,350,000 population. Divided to each person it is not too much.(4) But now, the GDP of China is $10.886 trillion! GDP Almost MISSING SUBJECT is almost 10 times that of 1974. (4) In education, China has an absolute increase. Back to 50 years ago, Chinese education was smashed by the Chinese government itself for some reason witch the leader of China vain hoped he can make the China a great country by his own way of education which renew the new education at seam time abolish the old one. The government had shut down all the schools included the elementary schools, middle schools and high schools and also universities. (1) Also, many teachers stood out to disagree that idea, but it is was useless. Since 1970 the leaders of China have changed the policy of education; finally educate work is running again. Fortunately, since 1989 almost 100% child will go to school study which is a great thing for China developing. Now from the elementary school to middle school, all the fee was pay by the Government. Also from the statistics of number of school and student during that time it is not hard to find this tremendous increase: 1965, China has 1681000 elementary schools it is 4.9 times of the number of elementary schools China has in 1949. 1965, China has 80993 middle and high school it is 14.1! times of the number of middle and high school China has in 1949. 1965, China has 434 universities it is 1.3 times of the number of university China has in 1949. All the number of students who attend in class was 13126300000,5.4 times of the number of students who attend in class in 1946.(5) So these are the main differences of China now than the China 50 Years ago. Health had has been enhanced greatly, also the economy and education. Also the economy and education had numerous intensifications during those 50 years. This girl might be cheerful dancing with a vagrancy singer. This vagrancy singer was playing the music for this little girl dancing.
there might have had a war happened here before. Since the people and building here look like so poor . She might become the youngest dancer in this street. That man could be her father. Also this little gie=rl might be saying: “thank God.” If this man had become famous, he could had not remember this girl. If I won a lot of the money, I would buy a big house which would like White House.
If I decide to go out this weekend, I will stop play my computer game now. If you visit my county, I will recommend you visit my hometown. If I have enough time this year, I will go to Japan. most people would be a lot happier if they didn't need working. If I were a bird, I would like to fly to the extraordinary place of the sky. I'll be annoyed this month if I will be asking to finish my history paper. If I had enough time this month I would like to travel around the world. In America there are a lot of sports I want to give a shot before I died.
