Ladies and gentlemen,
I am honored to stand here to share with you on such a important subject as climate change.Yes ,it is global warming . Let me give you two phenomenons.
Here is the first one. More and more people used to be using air condition ，but how many people ever thought whether this new ?hobby? will bring side-effects or not? Maybe just few people. In fact, the side-effect is apparent. The emissions of gases exhausted from air conditioning contain a lot of methane ***这里可以停顿一下***which could cause global warming. By the way, air conditioning will waste a lot of electricity .
The second one is about the increasing amount of cars. According to the statistics, in 21st century, there are 7 millions cars in the world, a large amount of exhaust gases has seriously influenced us, such as: cough, throat inflammation.
This two phenomenons are just few part of reason which change our environment badly. There are many other reasons.
In nearly 100 years, the average global temperature experienced twice fluctuations which is “cold-warm-cold-warm”. Generally, it is the trend that global climate is becoming warmer and warmer . In 1980s,global temperature rised apparently. According to Chinese scientists, the average temperature in China has risen by 1.1 degrees
centigrade in the last 5 decades. It is higher than the reported global average. We are seeing more frequent bouts of extreme weather in many parts of the country. For example, last spring, the most severe drought in 50 years hit northern China affecting the livelihood of 4 million people. Environmental damage and climate change is a reality for us. Out of the world?s most polluted 20 cities, half are in China,70% of Chinese rivers are polluted . China has become the largest carbon emitter of the world.
It is really thought-provoking***发人深省***. Who pays for it ? First,as the pace of human high-tech development process goes quiker and quiker, the side-effects with the science development reflected, global warming is one example. more and more greenhouse gases with the development of economy are being discharged into the air.About 70% of the greenhouse gases has been composed of carbon dioxide,which is considered as one of the greatest causes of global warming . It has harmful effects,causing the sea level to raise and many natural disasters to strike. On the other hand , scientists in one wave after another try to awaken us to the growing threat of global warming.But many coutries tend to turn a deaf ear***充耳不闻*** to the scientists?warnings.In fact,the earth?s atmosphere is definitely being warmed and the problem is largely man-made. A wise way is that we should get moving to protect ourselves. So the public demand that all nations should taket strong measures to prevent the increase of the earth?s temperature.
In my opinion, it is the high time for us to take action. In order to save the earth, we should try to do things below: no air conditioning, use recycled paper,abandon meat food, don?t use plastic bags,take a bus.It is little drops of life.As long as everyone takes action, it will be a powerful strength to rescue our planet. All countries are supposed to take the legislative initiative as soon as possible.Only in this way can the global warming be put under control.
