Global Warming

In recent years, we have seen how the world has slowly been destroyed due to the large amount of carbon dioxide and substances that will be the ozone layer. All these chemicals are produced by industries and the pollution produced by cars. Many people have become aware of the case and have done things to try to change that, but you need to change the world not only of a few because it is a too great harm we have caused the planet and if we do not do our part the planet could be history and all disappear and nothing would exist, what we call Earth. Become aware of the seriousness of the case!!
