It would magnify all of the effects of UV on human health, both positive (including production of Vitamin D) and negative (including sunburn, skin cancer, and cataracts). In addition, increased surface UV leads to increased tropospheric ozone, which is a health risk to humans.
Now, ClO reacts with an ozone molecule to form a chlorine atom, and two molecules of oxygen. The free chlorine molecule again reacts with ozone to form chlorine monoxide. The process continues, and this results in the depletion of the ozone layer. Ozone layer depletion first captured the attention of the whole world in the latter half of 1970, and since then, a lot of research has been done to find its possible effects and causes. Various studies have also been undertaken to find out a possible solution. Effects: For every 1% of ozone depleted, 2% of UV-B is able to reach the planet which is harmful because it can cause skin cancer. Researchers have predicted that 60 million Americans by 2075 will get skin cancer and with one million dying. The UV radiation splits the chlorine from CFC's which attracts one of the three ozone atoms and destroys the ozone into ordinary oxygen. CFC's were ordinarilly used to replace the ammonia and its effects. Causes. The main cause of Ozone Depletion are CFCs. CFC's drift in the environment until they reach the stratosphere. The UV radiation splits the chlorine from CFC's which attracts one of the three ozone atoms and destroys the ozone into ordinary oxygen. CFC's were ordinarilly used to replace the ammonia and its effects. The Impacts of Ozone Depletion. Stratospheric ozone filters out most of the sun's potentially harmful shortwave ultraviolet (UV) radiation. If this ozone becomes depleted, then more UV rays will reach the earth. Exposure to higher amounts of UV radiation could have serious impacts on human beings, animals and plants, such as the following: 1  Harm to human health: 2  More skin cancers, sunburns and premature aging of the skin. 1 Cataracts (a clouding of the lens) are the major cause of blindness in the world. 2  A sustained 10% thinning of the ozone layer is expected to result in almost two million new cases of cataracts per year, globally (Environment Canada, 1993). Ozone depletion is the process where ozone holes are created in the  ozone layer. It is caused due to the action of chloro-floro-carbons  on the ozone molecule to break it down to oxygen. Ozone depletion is a long term decrease in average ozone concentrations along any path between the Earth's surface and our Sun. The risk of ozone depletion was that too much ultraviolet radiation would reach the earth's surface, resulting in high levels of skin cancer. Industrial processes can result in slightly acidic rain as a result of high levels of sulphur dioxide and nitrogen oxide pollution. Consequences of ozone layer depletion Since the ozone layer absorbs http://www.answers.com/topic/ultraviolet ultraviolet light from the Sun, ozone layer depletion is expected to increase surface UVB levels, which could lead to damage, including increases in http://www.answers.com/topic/skin-cancer. The risk of ozone depletion was that too much ultraviolet radiation would reach the earth's surface, resulting in high levels of skin cancer. Industrial processes can result in slightly acidic rain as a result of high levels of sulphur dioxide and nitrogen oxide pollution. Even minor problems of ozone depletion can have major effects. Every time even a small amount of the ozone layer is lost, more ultraviolet light from the sun can reach the Earth. Every time 1% of the ozone layer is depleted, 2% more UV-B is able to reach the surface of the planet. UV-B increase is one of the most harmful consequences of ozone depletion because it can cause skin cancer. The increased cancer levels caused by exposure to this ultraviolet light could be enormous. The risk of ozone depletion was that too much ultraviolet radiation would reach the earth's surface, resulting in high levels of skin cancer. Industrial processes can result in slightly acidic rain as a result of high levels of sulphur dioxide and nitrogen oxide pollution. Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% in the total volume of ozone in Earth 's stratosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions. As explained above, the primary cause of ozone depletion is the presence of chlorine-containing source gases (primarily CFCs and related halocarbons). In the presence of UV light, these gases dissociate, releasing chlorine atoms, which then go on to catalyze ozone destruction. Effects of the Ozone Hole. Thinning of ozone layer means getting direct in touch with ultra violet rays which can cause skin cancer or skin irritation which can lead to death. A decrease in 1% of ozone layer can cause 5% increase in cases of skin cancer.  Ozone depletion would magnify all of the effects of UV on human health, both positive (including production of Vitamin D) and negative (including sunburn, skin cancer, and cataracts). In addition, increased surface UV leads to increased tropospheric ozone, which is a health risk to humans.
