Depletion of Ozone Layer
Depletion of Ozone Layer (Ozone hole)
Human activities have resulted in big problems with regard to the atmosphere like rising level of carbon dioxide and degradation of atmospheric ozone.
There is a layer of ozone gas (O3) in the upper atmosphere. This ozone layer is very important for the existence of life on Earth because it absorbs most of the harmful ultraviolet radiations coming from the Sun which can otherwise cause skin cancer. It has now been found that the amount of ozone is getting depleted (reduced) due to which the ozone layer is becoming thinner and thinner day by day. The depletion of ozone layer is due to the use of certain chemicals. Ozone holes have been discovered over Antarctica and the Arctic circles. Scientists are worried that if ozone layer in the atmosphere disappears complete, then the harmful ultra-violet rays would reach the Earth and would cause cancer and also damage the plants.
