【考點】倡議書．

【答案】Dear fellow students，
With the development of economy，more and more greenhouse gases are being discharged into the air．Carbon dioxide makes up about 70% of the greenhouse gases，which is considered to be one of the greatest causes of global warming．It has harmful effects，causing the sea level to rise and many natural disasters to strike．So we must take effective measures to save our planet．
First，we should use more clean energy and less oil and coal．Second，we should go to work on foot or by bike instead of driving a car if possible．Third，we should plant more trees because trees can absorb the carbon dioxide in the air．Last but not least，we should form the habit of saving energy in our daily life.
Now I am here to call on everyone to take action together to make the environment better.
