Antarctic ozone enlarged 5x Fold Up

NEW YORK - All the people in the world should be seriously aware of the effects of global warming, which may be increasingly felt in the near future. It is reminded by NASA reported that the Antarctic ozone hole will be five times bigger this year.

United States Space Agency are recorded, the hole in the sky Antarctic ozone has dropped to 10.5 million miles. Greater at last year's 9.5 million miles or registration of land in North America. NASA admitted that they had made this observation since the last 30 years.

"Although still in the stage of worrying, it certainly would endanger humans later," said NASA scientist Paul Newman, told CNN on Friday (7/11/2008).

This ozone layer is the Stratosphere that could counteract harmful ultraviolet rays from space. Ozone hole that formed from the gas continues to be made by humans. Usually visible ozone hole in August and growing in September or October, before finally disappearing.

As previously known, ozone depletion is suspected due to changes in extreme climate, which occurs because the influence of global industry that produces high levels of pollution. Not to mention the domestic industries that use materials chlorofluorocarbons, or CFCs in equipment.

Currently in addition to threatening human lives, this depletion would also damage the polar bear population in the Antarctic, a thin layer of ice and excessive heat made life can be threatened polar bears.
