environmental protection
no one，regardless of race, religion or nationality, can deny that the world we live in is becoming increasingly intolerable because of the effects of global warming. according to many experts, even greater impacts are still on the way.
there are numerous causes for this problem. on one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory. on the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem.examda
it is urgent that immediate and effective actions should be taken right away. first, more trees need to be planted to help improve and beautify the environment. besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effect and achieved good results. in a word, there is a long way to go before we can take a comfortable world for granted again .

people around the world may feel that the climate has been getting steadily warmer and warmer in recent years. places which used to be abundant in snowfall have frequently experienced snowfree(无雪的) winters. drought lasts longer in some dry areas. people find that without air conditioners they could hardly work or fall asleep on hotter summer days.
the side effects of global warming are alarmins. a warmer global climate melts the ice caps, raising sea levels. what is more, it disturbs weather patterns, causing droughts, severe storms, hurricanes (飓风). people suffer a lot from disasters relevant to global warming.
to stop global warming we should make immediate and continual efforts. we hope the situation will soon change. global warming catches and holds our concern, for it affects us and will affect our later generations. we cannot wait any longer. do it. do it right. do it right now.

in recent years do you think the weather suddenly turned hot had the cool autumn now almost until early october the hottest day in august has reached more than 40 degrees. these is different from normal vision we have ourselves to blame the curse.
today the term "global warming" has gradually penetrated into our life. the word sounds very academic even feel very far away from us so some people are not. in fact the effects of global warming is beyond our imagination: global precipitation redistribution glaciers and permafrost melt rising sea levels and so on. both harm the natural ecosystem balance more threatening human food supply and living environment.
now that you have aware of the dangers of global warming you should go to predict and improve it. imagine if global warming is melting in the 21st century the global average temperature rising gradually so the next super storms the next round of searing heat the next major natural disasters will happen? china? the united states? japan? no one knows. the debate has ended. scientists around the world agree points out that the earth's average temperature has increased nearly 1 ℃. due to all the early warning information human use of thousands of ships tens of thousands of the monitoring stations of the land and outer space satellite to monitor the earth together. scientists will have the most advanced computer data input model to estimate the earth can face the future. prediction results are worrying. forty years later the himalayan glaciers the water to the survival of millions of people are likely to disappear. the greenland ice sheet could melt in 50 years. currently half of the world's biodiversity in the amazon rainforest but the rainforest is likely to turn into a piece of barren land by the end of the century. is likely to be the future of the world like in the movie "the day after tomorrow" tornado ice fracture the temperature fell sharply ice storms freezing rain earthquake flood tsunami volcanic eruption... this is not a crazy fantasy if humans don't stop destroying the environment it will become a reality!
however in the warming is also good. global warming on rice in heilongjiang province has played a large role.
just global warming to human future development is still the do more harm than good.
in order to save the planet we should try to be: don't open air conditioning use recycled paper environmental protection to leave the meat with nitrous oxide don't use plastic bags r22 by bus; r22; little drops of life. actually it's not difficult to environmental protection as long as you support environmental protection is the best gift you gave the planet.
thank you all!

i often see on television, network is now the holes of the earth has been destroyed by human, if we are in different heart to protect it, the destruction of the earth will be completely in the near future. faster and faster, with the development of human science and technology science and the negative effect gradually manifested, then let me give you a few examples to illustrate why experts predicted that the earth will be gone after so many years.
first of all, global warming is one example, soak in the hot weather in summer air conditioning becomes a new "hobby", but what do people ever thought of air conditioning can bring negative effect? gas air conditioning to contain large amounts of methane, to the outside is the leading cause of global warming gases, methane and air conditioning will waste a lot of electricity, so try to avoid using the air conditioning or appropriate use.
another reason is that carbon dioxide, automobile exhaust and factory waste gas containing a large amount of carbon dioxide, and carbon dioxide are most likely to lead to global warming. cars now, too much exhaust serious affect our nong cough, throat inflammation... . according to concerning sectional statistic china's per capita emissions of carbon dioxide emissions every year 2. 51 tons a year! the changes in the harsh environment around us.
more important reason is that: reduce forest, farmland, water damage and serious water pollution, fresh water supply is a problem, many parts of the draft has become a big problem. now countries are massive effort, demanding, and costs "of the south-north water diversion project".
in order to save the planet, people all over the world should be: don't open air conditioning, use recycled environmental protection bags, don't use plastic bags, take the bus, don't throw waste batteries... such as the dribs and drabs in life. in fact, environmental protection is not difficult, as long as you support is the best gift you give earth environmental protection, take action, this is a powerful force!

earth’s temperature begins with the sun. roughly 30 percent of incoming sunlight is reflected back into space by bright surfaces like clouds and ice. of the remaining 70 percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere. the absorbed solar energy heats our planet.
as the rocks, the air, and the seas warm, they radiate “heat” energy (thermal infrared radiation). from the surface, this energy travels into the atmosphere where much of it is absorbed by water vapor and long-lived greenhouse gases such as carbon dioxide and methane.
when they absorb the energy radiating from earth’s surface, microscopic water or greenhouse gas molecules turn into tiny heaters— like the bricks in a fireplace, they radiate heat even after the fire goes out. they radiate in all directions. the energy that radiates back toward earth heats both the lower atmosphere and the surface, enhancing the heating they get from direct sunlight.
this absorption and radiation of heat by the atmosphere—the natural greenhouse effect—is beneficial for life on earth. if there were no greenhouse effect, the earth’s average surface temperature would be a very chilly -18°c (0°f) instead of the comfortable 15°c (59°f) that it is today.
