more and more people are traveling by private cars. CO2 makes up about 70% of the greenhouse gases, and many factories have polluted the air into the air. For example. Third.What&#39, which emit a lot of harmful gases, we should plant more trees,it has bad effect on our environment and our health. There are many reasons for this problem. First, we should use more and more clean energy and less oil and coal. Ss more . The most important point is we should make a habit of saving energy in everyday lifeNowadays , we should go to work by bus or on foot instead of driving.So we must do something to avoid these things from happening. And this problem become more and more serious, with the development of economies around the world may feel that the climate is becoming more and more warmer

Global Warming and the Greenhouse Effect
The Earth is kept warm by it's atmosphere, which acts rather like a woolly coat - without it, the average surface temperature would be about -18 degrees Centigrade. Heat from the sun passes through the atmosphere, warming it up, and most of it warms the surface of the planet. As the Earth warms up, it emits heat in the form of infra-red radiation - much like a hot pan emits heat even after it's taken away from the cooker. Some of this heat is trapped by the atmosphere, but the rest escapes into space. The so-called &greenhouse gases& make the atmosphere trap more of this radiation, so it gradually warms up more than it should, like a greenhouse (although a greenhouse actually does this by stopping warm air rising and escaping from it).
What Causes The Greenhouse Effect?
There are some natural greenhouse gases: water vapour, nitrous oxide, carbon dioxide, methane and ozone. However, over the past fifty years, production of carbon dioxide, nitrous oxide and methane has risen sharply, and a new type of chemical - the chlorofluorocarbon, or CFC - has been introduced as a refrigerant, solvent and aerosol propellant, but it is also a very powerful greenhouse gas, because it can trap a lot of radiation - one molecule of CFC is 12,000 to 16,000 times as effective at absorbing infra-red radiation as a molecule of carbon dixide.
This graph shows how much each gas contributes to the greenhouse effect, taking into account how much of it there is and how much radiation it can absorb.
The carbon dioxide comes mainly from burning fossil fuels in power stations, which also causes acid rain. It is also created by living animals breathing, and is naturally converted by plants back to oxygen. However, deforestation is reducing the planet's carbon dioxide absoring capability. Nitrous oxide is a by-product of nylon production, and is also released by fertiliser use in agriculture. The extra methane is produced in coal mining, natural gas production and distribution (natural gas is methane), and waste disposal. One fifth of all methane generated by human activity comes from microbial decay of organic material in flooded rice fields.
The Greenhouse Effect - Possible Solutions
Reducing use of fossil fuels would considerably reduce the amount of carbon dioxide produced, as well as reducing the levels of the pollutants which cause acid rain. This can be achieved by either using less energy altogether, or using alternative energy sources. You can help save energy in lots of ways:
*&&&& Turn off lights when you leave a room
*&&&& If you have a car, don't use it for short journeys
*&&&& Get your parents to insulate their house properly
*&&&& Basically, anything at all that uses less energy

全球变暖问题&Global&warming英语作文
&&& Nearly all scientists agree that the planet is warming. What is still open for debate is how much of the warming is due to human activites, and what all the potential effects will be worldwide. The Pentagon commissioned a report on the possibility of rapid climate change -- in particular examining the collapse of the north atlantic thermohaline conveyor (a process that delivers warmth from the gulf stream to Europe). &&& The report looks at historica precendent for such significant events, of which there are a few. The good news is that life survived all those previous events, the bad news is that there could be significant negative political and economic consequences to such a rapid shift.&&& In terms of what we can do, everyone can work to reduce carbon emissions... but we need to realize that such a fix will not stop warming for quite some time. Current models show that even with a complete halt to human based carbon emissions, that the world would not stop warming for decades. This same lag effect has made it difficult for scientists to finally agree that long term warming was taking place. Now we have enough data to be pretty sure on that, but we don't have many solutions as how to significantly slow the warming.&&& Ultimately, it would be ideal for the human race to move toward energy and economic growth solutions that would sustainable in the long long term (centuries or more)... To reach that state we need to move entirely to renewable energy sources and close the loop on materials and toxics used in manufacturing. This will probably take at least 50-100 years, but we'll never get there unless we start... and not getting there is not really an option for the human race as a whole.
