Global Warming

The Global Warming is a topic really popular nowdays, I think we need to stop contaminating because we are making a real damage to the world , maybe we don't still alive but to our son's future its in our hands and we should start changing that. The Global warming is due to all the mess and all the trash human creates. To stop this I think we should start using less cars and more bicycles , I think it sounds crazy but we can finally reach it someday.
