Global warming

Hello classmates ! today i´m going to talk about global warming, this is a very important problem who concern to all the people in the world, because the ecosystem of the planet it will collapse in a short time if we don´t do anything.

The global warming refers to the rise of temperature in the last century, and that rise it´s for the human influence, for the emission of carbon dioxide and other gasses. This rise is generating a climate change, where the retreat of glaciers, expansion of desert, ocean acidification and the extinction of different species are the most important problems in this moment.

United states in many countries and to many people it´s the model to follow, and many countries in this moment are following his way of life, without knowing that the earth it´s not going to hold very much if we spend and consume like United States. United States is the clear leader in the emissions of carbon dioxide and it´s not a model to follow.

Our way of live should be in harmony with the nature, and we need to understand that there is only one world, and we should be more careful with it. We should develop more the renewable energies and live with more selfsustainability.
