Abstract
There are many situations where human activities along with natural inhabitant have significant effects on the environment; Ozone layer depletion is one of them. The objective of this paper is to review the origin, causes and effects since a specific time zone and bio effects of ozone layer depletion as well as the protective measures of this vanishing layer. The role of the Ozone depleting substances on the stratosphere, where chlorofluorocarbons and other halogens are major ozone depletes. One of the main reasons for the widespread concern about depletion of the ozone layer is the anticipated increase in the amounts of ultraviolet radiation received at the surface of the earth and the effect of this on human health and on environment. The prospects of ozone recovery remain uncertain. In the absence of other changes, stratospheric ozone abundances should rise in the future as the halogen loading falls in response to the regulation. However, the future behavior of ozone will also be affected by the changing atmospheric abundances of methane, nitrous oxide, water vapor, sulfate aerosol and changing climate.
