Ozone Hole

There is a thick layer of ozone gas which is placed in the upper atmosphere and acts as a protection for the harmful ultra-violet rays.

Due to the ozone layer is present in the upper atmosphere preventing the majority of the ultra-violet radiations coming from the sun. The highly useful ozone layer in the upper atmosphere has been threatened and harm by rising human activities in increasing the use of chemical called as chloro fluoro carbon (dichloro – difluoro methane) through the air conditioners, refrigerators, and many more devices, which emit this chemical.

History of Ozone Hole – Scientists observed a hole in the ozone layer is called ozone hole, which covers the upper atmosphere in the year 1980s and this ozone hole was identified over the region of Antarctica. The ultra-violet rays, which were previously approximately wholly blocked by the ozone layer can currently go into the Earth’s lower to some extent through the ozone hole. This will regularly raise the level of ultra-violet radiation, which are harmful to nearly all forms of life.

Effect of Ozone Hole – The main shortcoming or disadvantage of the ultra-violet rays that it can cause a skin cancer. The effect of rise in ultra-violet radiation on the surface of the Earth due to ozone hole might be a rise of skin cancer along with male individuals and animals. The extreme ultra-violet radiation also harms the plant. The main cause of for the depletion of ozone hole is the use of chlori fluoro carbons. The chloro-fluoro carbons are used in spray cans as refrigerants react with the ozone layer and damage it. Since the chloro-fluoro carbons deplete the useful ozone layer, so the use of this chemical is banned in the whole world to protect the ozone layer. The emissions, which are produced by nuclear exolosions and supersonic jet airplanes may also cause the depletion of ozone layer in the upper atmosphere
