Many years passed from the day that the man started to discover the world. It all started because of evolution. Since a very long time, the man has been evolving, created many thing, destroying others. One thing we can be sure: the man completely changed the world. It was our curiosity that made us create the world were we live in.

       After all this years of development, we have made many great progresses. Now we can talk with who we want, wherever he is throught the Internet or we can travel arround the world by many ways, those are one of the best inventions that the man did. But with all those progresses, we are forgetting something, someday we can have the technologies we want, but we don’t have a planet to use them.

       This is the problem we live nowadays, the global warming. It all started at late 18th century in Britain, with the industrial revolution. Since then the population started to multiply, and multiply, to the numbers that exist today. It was after the industrial revolution that the greatest inventions started. Electricity and the car are one of the examples. With the large numbers of factories, and the increasing number of cars, greenhouse gas concentrations increased from there on.

       Some years ago, humankind started to worry about this problem. Many renewable energies have been proposed since there, but he haven’t found any with the efficiency of fossil fuels yet. However, there are some actions that we all can do to help the environment, like recycling, or going to work in the public transports. Everyone must be aware that the world need our help. If everyone help maybe we can avoid the destruction of environment.
