Effects of ozone depletion are: 1. Ultra violet rays will cause more sunburns, cancer and cataracts (blurring and clouding of eye that lead to blindness) and immune impair systems, damage of the deoxyribonnucleic acid [DNA]. In USA the number of people who are now getting skin cancer due to ozone depletion had increased 4 times- approximately 22 000 deaths per year. 2. Effects to plants. Many plants that are sensitive to ultraviolet will died out, especially key crops such as cotton, soyabeas, rice, beans, peas, and others. Effects to marine life. Effects to Phytoplankton form the foundation of aquatic food webs. Phytoplankton productivity is limited to the euphotic zone, the upper layer of the water column in which there is sufficient sunlight to support net productivity. The position of the organisms in the euphotic zone is influenced by the action of wind and waves. In addition, many phytoplankton are capable of active movements that enhance their productivity and, therefore, their survival. Exposure to solar UVB radiation has been shown to affect both orientation mechanisms and motility in phytoplankton, resulting in reduced survival rates for these organisms. Scientists have demonstrated a direct reduction in phytoplankton production due to ozone depletion-related increases in UVB. One study has indicated a 6-12% reduction in the marginal ice zone.

EFFECTS OF OZONE DEPLETION Reductions in ozone levels will lead to higher levels of UVB reaching the Earth's surface. The sun's output of UVB does not change; rather, less ozone means less protection, and hence more UVB reaches the Earth. Studies have shown that in the Antarctic, the amount of UVB measured at the surface can double during the annual ozone hole. Effects on Plants Physiological and developmental processes of plants are affected by UVB radiation, even by the amount of UVB in present-day sunlight. Despite mechanisms to reduce or repair these effects and a limited ability to adapt to increased levels of UVB, plant growth can be directly affected by UVB radiation. This affects the food chain and in turn affects all living beings. Effects on Marine Ecosystems Phytoplankton form the foundation of aquatic food webs. Phytoplankton productivity is limited to the euphotic zone, the upper layer of the water column in which there is sufficient sunlight to support net productivity. The position of the organisms in the euphotic zone is influenced by the action of wind and waves. In addition, many phytoplankton are capable of active movements that enhance their productivity and, therefore, their survival. Exposure to solar UVB radiation has been shown to affect both orientation mechanisms and motility in phytoplankton, resulting in reduced survival rates for these organisms. Scientists have demonstrated a direct reduction in phytoplankton production due to ozone depletion-related increases in UVB. As phytoplankton are the most important element of the marine ecosystems, this affects the ecosystem greatly. Effects on Biogeochemical Cycles Increases in solar UV radiation could affect terrestrial and aquatic biogeochemical cycles, thus altering both sources and sinks of greenhouse and chemically important trace gases like carbon dioxide, carbon monoxide, carbonyl sulfide and possibly other gases, including ozone. These potential changes would contribute to biosphere-atmosphere feedbacks that attenuate or reinforce the atmospheric buildup of these gases. Effects on Human Health UVB causes nonmelanoma skin cancer and plays a major role in malignant melanoma development. In addition, UVB has been linked to cataracts. All sunlight contains some UVB, even with normal ozone levels. It is always important to limit exposure to the sun. However, ozone depletion will increase the amount of UVB and the risk of health effects. It will also cause more sunburns, cancer and impair immune systems, damage of the deoxyribonucleic acid [DNA]. Effects on Materials Synthetic polymers, naturally occurring biopolymers, as well as some other materials of commercial interest are adversely affected by solar UV radiation. Today's materials are somewhat protected from UVB by special additives. Therefore, any increase in solar UVB levels will therefore accelerate their breakdown, limiting the length of time for which they are useful outdoors.

It effects on the ice(glaciers). After time goes by they will start to melt and the sea level will rise up to 5 meters. and also it will effect on human, for example easy to get sun burn and also easy to get skin cancer.

The UV rays are very dangerous to many plants and animals such as plankton. They will be among the first to die off. When they are near extinct, larger animals such as fish will die. The starvation epidimic will continue up the food chain until we won't have meat to eat. Since UV rays are dangerous to plants also we won't have many of them any more.Then we won't be able to eat our vegetables(echhh).Another thing to remember is that plants recycle the CO2 from the air and turn it into oxygen.

ozone depletion occurs when the ozone layer we be thickened and all of us will have easily skin cancer, sunburns and many skin sdiseases... ozone layer is important because it protects us from the UV rays, gamma rays and the other ray...
