What's the negative problem caused by climate change
In recent years, global warming in China is becoming more and more serious and the words ‘global warming’ always appears 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 countries 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 leads many animals and plants died out because of the changing of habitat. Even we humans are suffering from the flood and drought 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 effluent of greenhouse gas more strictly. As we know, these factories are producing lots of poisonous gas everyday which will 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 quantity of private cars. As the developing of economy, many people begin to own private cars. The burning of fuel can release a lot of carbon dioxide which is the main greenhouse gas that cause global warming. “Based on current growth rates, China's carbon emissions will equal today's entire global output by 2030”, warn Ning Zeng and colleagues in science. Data from Intergovernmental Panel on Climate Change(IPCC)also shows that the carbon dioxide will cause an increase of 1.4–5.6 °C in 2100 compared to 1990.
Third, enact some law to limit the logging of forest and pollution to the sea. It’s known that the forest and sea are main ‘factories’ to filter the nature air. They can absorb lots of greenhouse gas every year. However, as the rapid increase of population, lots of forest is being cut for people to live. The sea also got polluted by living rubbish and poisonous 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 economic. 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 environment problems than before. Industry pollution, dust storm, tail 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 our nature, it’s our duty to rejuvenate it.
