to WWFDear WWF,
My friend, Chen Ting, and I have been doing some research on endangered animals. We found that the habitat of polar bears is disappearing because the ice at the North Pole is getting warmer. I worry that when is disappears altogether, there will be nowhere for the polar bears to live.
First, I suggest we are very careful with the energy we use. Global warming happens because we are putting too much carbon dioxide into the air. One of the ways we do this is by driving everywhere by car. So I suggest we think carefully before using our cars unnecessarily.
Second, instead of using our cars we should think about traveling by bus or by train. These forms of transport are more environmentally friendly and do not put so much carbon dioxide into the atmosphere.
Third, we can join WWF which is fighting to save the habitat of the polar bear. We can raise money to help them by making and selling cakes, selling crafts or giving talent shows and charging money for our parents to watch.
I hope you will support us in our fight to save the home of the Polar Bears.
Yours sincerely Wu Xiao Xing
