It's sound strange that pollution can be beneficial for human being. It is strange but true. In the race of development; human have accessed damage to nature. They released a great deal of carbon dioxide that caused hole in the ozone layer which cause ultraviolet rays to access on the surface of earth.
This ultraviolet rays cause many skin disease. It causes global warming. We are very anxious about its possible effect. Visible cause is melting glacier and increasing sea level. We never think, even in the dream that global warming would be beneficial.
If we believe the claim made by the scientist of Cambridge University, the danger of ice age has been pushed ahead. According to peleoclimatology, (the study of change in the climate taken on the scale of entire history of earth) the Ice age will be started in the next 1500 years, according to the climate cycle of earth.
But it has been pushed ahead by human activity. They released so much carbon dioxide and made earth so hot that access release of carbon dioxide in the atmosphere pushed it ahead. Our atmosphere is so hot; if we stop releasing carbon dioxide. It will be hotter for next 1000 years.
So our one bad did rescued us from ice age. Present level of carbon dioxide in the atmosphere is 390 per one million particles. The ideal circumstance for freezing glacier is 240 particles of carbon dioxide per million particle.
This is good news for the inhabitant of this planet that their some bad deed saved earth form Ice age. If ice age would have been started the survival of human being would have been very difficult. Those people who are living in cold weather can survive but those who are living in the worm climate; it would have been very difficult to survive.
