The global warming

In 2003, waves of extreme heat caused more than 20,000 deaths in Europe and more than 1,500 deaths in the India. Also, the area of the Ártic polar is diminishing to a rhythm of 9% every decade, this is a fact that the scientists consider as an alarming sign of the future events.
The united states represents the 4% of the population's world, it produces the 25% of the contamination for emission of carbon dioxide to the combustion of fossil fuels, overcoming in more grade to the emissions of any other country. In fact, the United States emits more carbon dioxide than China, India and Japan together.
We can reduce The contamination that causes the global warming if we reduce the contamination of the vehicles and the generating plants of energy. We should use the technology to have cleaner automobiles and more modern electric power generators. We can begin to use renewable sources of energy like the eolic, the solar and the geothermal. Also, we can manufacture more efficient teams and conserve energy.
