The negative problem caused by climate change
In recent years, global warming in China is becoming more and moreserious and the words 'global warming' always appear on the news. Why do people begin to focus on these phenomena and get closer to a consensus that something must be done to reverse the effects of global warming? The answer is obvious: it has brought a huge damage to human beings. Many areas like Venezia and Singapore are facing danger of being flooded because the sea level rises from global warming. The balance of ecosystem between human and nature got destroyed seriously. It has led many animals and plants to die out because of the changing of habitat. Even we humans are suffering from the floods and droughts much more frequently than before.

Global warming is a major problem that can be improved in three ways by engineering. Firstly, the government of China should limit the effluence of greenhouse gas more strictly. As a developing country, China has to set up many factories, which produce lots of poisonous gas like Sulfur dioxide and carbon dioxide everyday. They bring a huge damage to the ozonosphere. David Perlman states "human industrial activity is largely responsible for global warming" (San Francisco Chronicle. February 19, 2005).

Secondly, the Chinese government should limit the numbers of private cars. With the development of economy, many people in China begin to own private cars. The burning of fuel can produce a lot of carbon dioxide, which is the main greenhouse gas that causes global warming. "Based on current growth rates, China's carbon emissions will equal today's entire global output by 2030," warned Ning Zeng (Science.February 8,2008). Data from Intergovernmental Panel on Climate Change(IPCC)also shows that the carbon dioxide will cause an increase of 1.4-5.6 oC in 2100 compared with 1990.

Third, China should enact some laws to limit the logging of forests and pollution to the sea. It's known that the forest and sea are main factories to filter the nature air. The sea can absorb 75% of carbon dioxide and trees can absorb 5% every year. However, with the rapid increase of population, lots of forests are being cut to leave more room for people to live. The sea also got polluted by living rubbish and toxic waste. If nothing is done to stop this, we will destroy our lives by ourselves.

In past few years, the government of China always did "First pollute then treat" to develop the economy. The effect is quite obvious. The GDP of China increased very fast in these years. Does it mean that the level of people's life increase at the same time? The answer seems to be 'NO'. China is facing more and more environmental problems than before. Industrial pollution, dust storms, exhaust gas of cars are filled in our life. So it's time for us to pay attention to the environmental problems. If we have destroyed nature, it's our duty to rejuvenate it.

That is really a serious problem which must be solved imediately.
