The Warm Earth
Now we can feel that the earth is more and more warming ,the temperature go up so obviously.But why?Because people cutting down the trees and so many factories pull out Carbon dioxide .I think we should protect the forests and stop the polluted gas into the air.Besides,we can go to work and the school by bus instead of drive cars.
The earth is our home town,we should try our best to protect it and keep it " cool".
