EFFFECT OF GLOBAL WARMING AND OZONE LAYER DEPLETION IN OUR ENVIRONMENT

ACKNOWLEDGEMENT I thank Almighty ALLAH for giving me this great opportunity for completion of these studies. My profound gratitude and immense appreciation goes to my humble supervisor Prof. Mohammed Hassan for his tireless effort, criticism contribution corrections and his time devoted towards the actualization of this project. My special gratitude and appreciation goes to my father Late MUAZU MOHAMMED for showing me the right way which lead me to success in my life. May almighty Allah have mercy upon him. My sincere gratitude goes to my mother AISHA ABDULLAHI for her prayers on me which are pillars of my strength in my studies. May almighty Allah reward her abundantly (AMEEN). ABSTRACT There are many situations where human activities have significant effects on the environment. Ozone layer damage is one of them. The objectives of this paper is to review the origin, causes, mechanisms and bio effects of ozone layer depletion as well as the protective measures of this vanishing layer. The chlorofluorocarbon and the haloes are potent ozone depletors. One of the main reasons for the wide-spread concern about depletion of this ozone layer is to anticipate increase in the amount of ultraviolet radiation received at the surface of the earth and the effect of this on human health and on the environment. The prospect of ozone recovery remain uncertain. In the absence of other changes, stratospheric ozone abundance should rise in the future as the halogen loading falls in response to regulation. However, the future behavior of ozone will also be affected by the changing atmospheric abundances of methane, nitrous oxide, water vapor, sulphate aerosol, and changing climate.
