。The Fight Against Global WarmingSince our society has entered into a new century,at the same time,we human beings also meet with a dilemma.Can we develop economy at the cost of environment?On the one hand,Due to the economic development,it has provided numerous job opportunities,which has also improved living conditions and increases government revenues,However,on the other hand, the present serious environmental problems are largely caused by rapid development of economic.Heavy use of energy to enhance the human material,which caused unexpected disasters,and acid rain damage almost all over the world great plants and so on.Then,let me take global warming for example.What is global warming? Global warming is the increase in the average temperature of Earths near-surface air and oceans since the mid-20th century and its projected continuation . According to the 2007 Fourth Assessment Report by the Intergovernmental Panel on Climate Change, global surface temperature increased 0.740.18C (1.330.32F) during the 20th century .In nearly 100 years, the average global temperature goes through four fluctuations: cold, warm, cold again, and warm again. After 1980s, the temperature was ascending obviously. What caused global warming? It is caused by several factors. First,the wide use of coal and fuel,which causes the emission of carbon dioxide,the main gases that lead to greenhouse effect.Second,population explosion is one of the main factors of global warming; it also threatens the balance between man and nature. Third, atmospheric pollution is being on the rise, and it has already become an international major problem. It is also the basic problem of global warming. Forth, marine ecology and environment took a turn for the worse. That may lead to the damage of fresh water resources. Fifth,the forest resources are sharply decreased by natural changes and human actions. What are the negative effects caused by global warming? This serious environmental problem generates amount of destructive effects to the entire planet: ice melting, climate change, animals and plants extinction, and threat of human society. Primarily, as the temperature increases, ice melting is regard as the most intractable issue. Melting of ice raises the sea level. In addition, as a result of ice melting, landscape also transforms. Meanwhile, global warming also causes climate change to bring about many other awful effects such as more destructive storms, more fire disaster and more intense droughts. The second effect of global warming is to make many animals and plants endangered. Considerable data verified that more than 200 native plant species in the United States have gone extinct; more than 760 plant species in the U.S. are federally listed as endangered or threatened and 20 percent of our native plant species are in decline and on a conservation watch list.As same as plants, there are also many endangered animals generating which are imputable to global warming, such as Polar bears. Some scientists believe the Polar bears in Alaska would become extinct in 50 years time.These data warn us that we call for paying effort on survival of species.The last negative effect of global warming is more related to humankind. Global warming will also threaten human society. It will cause the infectious diseases too easy to spread and infect. Bacteria will hard to control through fast breeder reactor, and threat our lives. The house will be eroded by destructive insects and it may lead a vagrant life eventually. Whats more, global warming impedes outdoor activities. Some outside entertainment sports such as skiing and snowboard will be influenced by ice melting and climate change.So,you can see,it is high time that we took measures to protect our sole planet.First,Governments are the main force in the combat against global warming. On the issues concerning global warming, the variety of attitudes toward global warming is a greatest obstacle for us to win this combat. So, at first, all the countries must reach an agreement on striking a balance between developing economy and solving this environmental problem. Then, some effective policies should be adopted to reduce the emission of the greenhouse gases.Second,Common peoples involvements are the key to ease the global warming. One persons ability is slight, but if every one can make a little effort, there can be a big difference.What can we do for it? I think first, we can learn something about global warming, to be aware of it and to know our responsibilities to this planet. In addition, we can should not to make greenhouse gases, specifically, to take bus or ride bicycle instead of driving private car.Third,the most important one,we should reduce the use of traditional resources,instead,we should explore the new resources,in other words,what we called renewable resources,which inclu
