USA - a country defiding the humanity

I am not talking here about the wars started by USA in the name of the so called "fighting terrorism", but about the fact that an American is consuming and polluting more than anyone else on Earth.
In 1992 there has been a world union meeting in Kyoto, Japan, where all states presidents, except USA president, have signed a common act in which they agreed to do all efforts to lower CO2 emissions in the atmosphere in order to drop the temperature raising and stop the global warming. If we consider that USA is biggest polluter in the entire world we can see why Americans are not so loved anywhere in the world.

This poor attitude has not changed not even in 2009, in Copenhagen, where again, USA showed their total lack of respect to the humanity and refused to sign a real treaty to lower the CO2 emissions and halt the global warming.
The new renewable technologies cost huge amounts of money to implement and with the world crisis being in full development, most countries avoid to spent money on such things.
Today almost all voices are saying that the wheel has been put in motion and it's hard to believe that the humanity could stop his growth and progress stopping the CO 2 emissions in order to avoid the melting of all the glaciers in the world.
