Reductions in stratospheric ozone levels will lead to higher levels of ultra violet ray reaching the Earth’s surface. The emission of ultra violet ray from the sun almost same; rather, less ozone means less protection, and hence more UV reaches the Earth. Most of the cases human activities play the significant roll on the environment. Ozone layer damage is one of them. Different types of offensive ordered in the atmosphere such as CO2, different oxides of sulpher and nitrogen, chlorofluorocarbon etc. are the potential ozone depletors. Due to decrease of ozone layer, increase in the amounts of ultraviolet radiation received at the earth surface and it affects the living part of the environment. Though the possibility of ozone hole recovery remain uncertain, still there may be a little prospect of ozone recovery by developing nanostructure titanium oxide (TiO2) materials that can cause photo driven remediation reaction to control the offensive order in the atmosphere and recover the ozone layer to make the environment clean. The main objective of this paper is to review the origin and effects of ozone layer depletion as well as the possible protective measures of this layer.
