Abstract
The purpose of this study was to review the Causes, effects and prevention of the ozone layer depletion. Ozone layer is a part of the stratosphere which absorbs the harmful ultraviolet (UV) rays of the sun and prevents it from reaching the earth surface. Industrial activities, release chemicals into the air that can destroy ozone layer, this process known as ozone layer depletion. The main causes of ozone layer depletion are Chlorofluorocarbons (CFCs), Halons (HCFCs) and NOX (nitrogen oxides), depletion of stratospheric ozone, led to increased ultraviolet radiation at the earth’s surface as well as spectral shifts to the more biologically damaging shorter wavelengths, which is harmful to the human, plants and ecosystem. An international environmental initiative to lessen ozone depletion is known as the Montreal Protocol. This agreement required all nations to impose legal obligations on the reduction of CFCs and other comparable chemical compounds. As a result, an international fund has been set up to assist in introducing these nations to new and environmentally friendly technologies and chemicals.
