On the stage of the world now, Global Warming plays a important part known as a serious environmental issue.
Firstly , as for the causes(especially the man-made causes) of this issue .1)Burning fossil fuels,giving off more CO2 . Burning fossil fuels is one thing that causes pollution. Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they give off a green house gas called CO2. Also mining coal and oil allows methane to escape. How does it escape? Methane is naturally in the ground. When coal or oil is mined you have to dig up the earth a little. When you dig up the fossil fuels you dig up the methane as well. It results in greenhouse effect .And then , Global Warming comes on ~~
2)More rainforests extincting,absorbing less CO2.
Greenplants can absorb CO2,but now,people destroy forests more and more cruelly.They use trees to make paper or for other usages.So, less trees take up CO2 at themoment.Thus,greenhouse effect is more and more" popular".
The next , when it comes to the solutions.Now , people begin to take some steps to slove this problem.For example, people in China urge " Protect natural forests!Plant more trees as possible as you can!"I think this quote is quite right.Please protect our forests!
