The weather is become warmer,even the polar bears come to China,too.They feigned themselves with black paint so that they could be looked like a giant panda.In order to keep the weather from warming,we advocate the life of low carbon.To walk ,by bike or choose public traffic as much as possible.Shopping with our own shopping bags.The earth belongs to the all human being.All of these trifles need to be done by ourselves.We thank you,you also can thank yourselves .Let's recover the shine of the most beautiful earth!
