This ozone layer absorbs almost all of the shorter waves of UV rays that enter the earths atmosphere‚ and prevents it from doing any severe damage on the living organisms on earth. The fast depleting ozone player is a rising concern. UV radiation is known to be one of the leading causes of Skin cancer. UV rays from the sun and other sources such as tanning

A lot of people in our community cant afford the treatment to cure this type of cancer‚ and some sever cases of skin cancer could cause death. So why not prevent this from happening and wear your sunscreen? A lot of scientists now days are focused on how the chemical reaction of ultraviolet rays are causing our ozone layer to brake down.

This year’s ozone hole over the South Pole is one of the worst‚ despite scientists only a year ago saying it had shrunk to its smallest size. By September 12 the hole above Antarctica was 26 million square kilometres‚ Nasa and the National Oceanic and Atmospheric Administration said. The hole – which grows each spring and then shrinks again each year – was among the 10 worst since records began 26 years ago. Colder-than-average temperatures in the stratosphere had caused the larger-than-average

The overwhelming majority‚ 99 percent of the ultraviolet rays that reach the Earth’s surface‚ are UVA. “When the ozone layer becomes thin‚ however‚ more UVB radiation reaches Earth’s surface and may have hazardous effects on organisms. For example‚ studies have shown that UVB radiation penetrates the ocean’s surface and may be lethal to marine plankton to a depth of

All the pollution that humans send up into the atmosphere thins the Ozone Layer. The Ozone Layer is meant to filter out the harmful UV rays‚ but because there is now a hole in it‚ some rays get through and heat the water temperature (Global Warming). The coral cannot survive the warmer sea temperatures. Other threats: -Crown of
