What is ozone depletion and its harmful effects |
| Answer» UV rays are very harmful to living things. It can cause diseases like skin cancer and can also alter the climate drastically. The ozone layer protects us from these harmful rays and is essential for life on earth.The ozone layer is not uniform throughout the earth; it is found in a thick layer at some places and a thin layer at others. If this\xa0layer becomes too thin, it cannot stop the UV rays from entering the earth and we say that a hole is formed in the ozone layer. Antarctica has the biggest ozone hole followed by the Arctic region and the Tibetan plateau. In these places, the layer was naturally thin, but over the years due to air pollution, these holes have grown bigger and thinner. They are a serious cause of worry across the world.The harmful effects of depletion of ozone layer are :(i) Due to depletion of ozone layer, UV radiation reaches the earth. These UV radiation causes skin cancer, damage to eyes and immune system.(ii) This depletion of ozone layer may also lead to variations in global rainfall, ecological disturbances and dwindling of global food supplies. | |
