Factors contributing to ozone layer depletion and its consequences on human health and the environment

The stratosphere layer held the majority of the ozone concentration. Ozone is less abundant in the atmosphere as compared to oxygen. The ozone layer serves as a protective layer and a shield against the sun’s harmful radiation. Ozone layer depletion increases the concentration of ultraviolet radiation on earth and in the atmosphere. These UV rays have an adverse impact on humans and the environment. Chlorofluorocarbons (CFC) are the main factors responsible for ozone layer depletion. Other substances, such as chlorine, bromine and uncontrolled rocket launching activities are also contributed in the depletion of ozone layer. Ozone layer depletion causes several severe disorders and diseases in humans. Depletion of the ozone layer also increases the risk of cataracts, eye damage, sunburn and skin cancer problems in humans. UV rays also directly influence aquatic and terrestrial ecosystems and their biota.
