Nowadays , with the development of economies around the world may feel that the climate is becoming more and more warmer. CO2 makes up about 70% of the greenhouse gases. There are many reasons for this problem. For example, more and more people are traveling by private cars, which emit a lot of harmful gases, and many factories have polluted the air into the air.
And this problem become more and more serious.What's more ,it has bad effect on our environment and our health.
So we must do something to avoid these things from happening. First, we should use more and more clean energy and less oil and coal. Second, we should go to work by bus or on foot instead of driving. Third, we should plant more trees. The most important point is we should make a habit of saving energy in everyday life.
Global warming is a natural phenomenon. Because people burning fossil fuel, such as oil, coal, or deforestation and the burning will produce large amounts of carbon dioxide, the greenhouse gas, these greenhouse gases on the radiation from the sun visible light has high permeability, and the long wave radiation emitted from the earth with a highly absorbent, can strongly absorb infrared radiation on the ground, resulting in the earth's temperature to rise, the greenhouse effect. And when the greenhouse effect will continue to accumulate, resulting in gas absorption and emission of energy balance, energy accumulation in the earth atmosphere system, resulting in rising temperature, resulting in the phenomenon of global warming. Global warming will make the global distribution of precipitation, glaciers and permafrost melting, sea level rise, not only endanger the balance of natural ecosystems, but also threaten the survival of mankind.
On the other hand, due to land caused by greenhouse gas emissions, temperatures, and ocean temperature difference smaller, nearly caused by the air flow is decelerated......
What can we do about global warming?
Science suggests that to mitigate the human contribution to global warming, we should reduce carbon dioxide and other greenhouse gas emissions. Because some additional warming is inevitable—even if we achieve significant greenhouse gas reductions quickly—we should make plans to adapt to coming climate change. If we are unable to control emissions and/or adapt to unavoidable changes quickly enough, a carefully selected geoengineering strategy could conceivably provide an emergency stopgap to slow global warming. As yet, however, several of the strategies being discussed are very risky and unproven.
Controlling emissions is a large, complex, and potentially expensive problem that no single strategy will solve. On the other hand, the costs of uncontrolled global warming will probably also be significant. Many economists have concluded that putting existing scientific and technological strategies into place and developing new ones may stimulate the economy, and would also generate significant near-term benefits in public health through air pollution reduction.
With the development of economy, more and more greenhouse gases are being discharged into the air. CO2 makes up about 70% of the greenhouse gases, which is considered to be one of the greatest causes of global warming. It has harmful effects, causing the sea level to rise and many natural disasters to strike. So we must take effective measures to save our planet. First, we should use more clean energy and less coal and oil. Second, we should go to work on foot or by bus instead of driving a car if possible. Third, we should plant more trees, because plants can turn CO2 into oxygen. More importantly, we should form the habit of saving energy in our daily life.With the development of economy, more and more greenhouse gases are being discharged into the air.

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.com
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
With the development of economy, more and more factories have been set up. More and more trees have been cut down so that more and more buildings can be built, because more and more babies are born. Many people don't pay attention to the environment, so the earth is getting warmer and warmer. As a result, the ice is always melting, even at the North Pole. So if it goes on like that, many cities along the coast will be covered by water. Many people will lose their homes. In order to stop this happening, we should stop cutting down trees, polluting rivers and lakes. Factoreis should make the smoke or water cleaned before pouring our into the sky or rivers and lakes. Then we, even our next generation can live a happy life.
