you know my friends, when I was little, we had a lot of snow in winter, snowdrifts were 2 meters long, and now the winter has become much warmer, sometimes it even rains and snow is much less. I will not argue that this is global warming, perhaps this is some kind of cyclical change. but the fact that we arepeople are very much contaminated by the earth around us, in this I am sure. look how much garbage is around !!! there are even islands out of garbage !!!!
