Causes of Global Warming

Date:19/7/08 SAT
I have decided to research on how global warming happen as it is a major part in my question. At first, I thought that global warming is a serious case as the whole world is doing their part to prevent or slow down the rate of global warming.However, a lot of people still refuse to help out in this and continue polluting our environmet, such as using more and more electricity and produce more and more carbon dioxide and poisonous gaeses to the atmosphere.
Below is a graph of the temperature change on Earth in the past few years




This graph shows that the temperature is increasing very rapidly due to global warming. As the temperature get higher and higher, more ice from the Polar region would melt and there would be more water in the Earth. Hence, more floods will occur at any parts of the world and in a few more years time, there would be no land for animals like us to live on as it is covered with water. The graph on the right shows the amount of ice still remained in the Polar region.

Therefore, I would encourage everyone not to waste electricity and save it as it would greatly help the environment and the world. When we waste electricity, more fossils fuels had to be burned and more carbon dioxide is produced and will harm the environment. The graph on the left show the rapid increase of total carbon dioxide emissions for three regions.Together, we can have a better future by saving the world where we live!!!
