Copenhagen Climate Change Conference

Global warming..
Most people know what it means to the earth.
We know that the earth has changed because of the things we have done to the earth.
Although we know that the climate will be changed and the environment will change
if we don't take action, it is very hard for us to do that because that is a global problem.
In some countries, they try to be environmentally-friendly, but other countries don't care
about the ecology much because they care more about their economic development.
I know that the developing countries don't want to care about the ecology, but it is time to
solve the problem globally for the future.
Also, the U.S. government should take action on global warming, because they are the
most influential government in the world.
