An Inconvenient Truth

Not long ago, the last Tuesday as usually I went to American Corner to watch a movie with my friends. Till we got there I believed that another movie would be presented but we were shown the An Inconvenient Truth. Before the start of the film a native English speaker teacher of University of Pécs performed the real problem of the world that was summarized in the movie: global warming.
The film by Al Gore represents the way our climate changes and has changed so far. Al Gore says the global warming and the things relates to it are not a political but a moral issue. He says that people should hold together and do something to prevent that can be prevented yet. So this film calls our attention to the approaching dangers.
For instance it made perceptible what would happen if the idea of sinking headlands referred to Florida and Shanghai or India. During the presentation pointed out that they would sink under water and lot of people would die I was shivering.
Another effect of the global warming on the world that shocked me was polar bears have not enough ice swimming on the water to climb on and rest after swimming a lot, so some of them drown.
Besides, there was an explanation what causes the global warming. The rays of the Sun are not allowed to leave after entering and warming up the Earth because of the harmful gases that we, human beings produce every day.
So I think the most desperate thing of all that the global warming exists due to US.
