GLobal warming...

Recently, I read some articles about Global Warming. This phenomenon seem to be getting more serious. I am sad to say that, human themselves are the main cause for this problem. Human activities such as logging, deforestating,and a lot more have contribute to global warming.
Now the researches in Artic shows that the five ice shelves along Ellesmere Island in the Far North, which are more that 4,000 years old, had shrunk by 23% this summer alone, just a short while. This indicate that our world is heading to "doomday". So let us all together play our roles to save our beloved planet Earth for the sake of our future generation.
