Dear Editor,

Recently we have made a discussion about the prevent of global warming in our research

group. Everybody has become aware the green-house effect, what has drawn the attention of the world. Many scientists on the summit of COPENHAGEN warned any rise above 2 degrees could lead to a sea level rise threatening islands and coastal cities, kill off many specie of animals and plants. As a result of, every nation should work together to limit the release of carbon dioxide. Everybody should shoulder the responsible for fight against climate change, and a low carbon life is a must.

I think fight against global warming is part of environmental protection. If we humans are more friend to nature, nature will be friendly, too. It’s time everybody rethink our role in keeping peace with our mother, nature.

Yours sincerely,

Lihua
