Global warming has become a major problem that the dangers is often being underestimated by many people. People may not realize that their everyday action is worsening the "global warming". For example,the main cause of global warming is an increase in greenhouse gases such as water vapor,carbon dioxide,etc. Greenhouse gases is what absorbs the heat from the sun, it slows the heat's escape from the earth,without the greenhouse gases,the earth will be colder by approximately 30 degrees celcius,which does not make life possible for our current ecosystems. Basically we humans could not live without greenhouse gases,but,excess of greenhouse gases is not a good thing either. The use of fossil fuels,deforestation releases the carbon dioxides and other "heat trapper" into the atmosphere,which results in the excess of greenhouse gases concentration. The excess of greenhouse gases will results in more heat trapped in our atmospheres,since the greenhouse gases is what keeps the "heat" from exiting the earth. The results are obvious,the earth is getting way hotter,i am sure all of you already realizes it. The increase in the earth's temperature will melts the ice on the arctic and rises the sea levels. The experts predicts that in 2100 the sea levels will rises by at least 25 meters. That is not all the effects people,the increasing global temperatures will surely increase the amount of natural disasters like hurricanes,floods,heat waves,you name it. There are some things that you can do to help the earth,such as applying 3R,reducing the amount of electricity you use,reduce using the air-conditioner,plat more trees,and many more. In conclusion,it is the act of humans that causes the global warming,and it is also humans that will feel the effects,but there is still hopes that we can help the earth.
