The most serious environmental problem

—global warming

There are many big environmental problems facing us on the earth today but I think the most serious one is global warming. Global warming means an average increase in the earth’s temperature. It is caused by gases from cars waste gases from factories destruction of forests and so on. Global warming will cause changes in climate. A warmer earth may lead to more rain and the rising of the sea level. In this case some land will be flooded and also it will have a bad influence on both human beings and wildlife.

So how to solve the problem of global warming is really urgent for human beings. What can we do? First of all people should be educated to raise the awareness of environmental protection. Also we should call for people to take action and encourage people to use bicycles instead of cars and clean poisonous gases before they come out of factories. Besides we should plant more trees. If we try our best to take better care of the earth we will make our world a better place.
