Through this project, I have realised that it is not all that difficult to save the earth. If we could spare just a little time to do something for the earth-for example, recycling drink cans instead of throwing them away-we will be able to do less harm to the earth.

There are more than 6 billion people in the world. To sustain 6 billion people, we have changed the world to suit our needs. First fire, then electricity,and then advanced technology. Even as you read this article, more and more greenhouse gases are being pumped into the atmosphere. Can we do somthing to help the earth?

After all that the Earth has given us, could we do something in return for the earth?
