Our Ozone Layer: Past, Present and Future

I decided to investigate the environmental issue of the depletion of the ozone. Although I score heard more things roughly the ozone, and the hole over Antarctica, I wanted to find out more and home plate nigh real facts on ozone depletion and what we bottomland do about it. The ozone horizontal surface refers to the ozone within the stratosphere, where over 90% of the earths ozone resides. The ozone socio-economic class absorbs 97-99% of the suns ultraviolet or UV light (The Ozone seam). This UV light has many damaging affects for humans, plants, and animals. In humans, exposure to UV light can increase the chances of getting skin cancer and cataracts. It also harms pabulum crops and other plants, as well as many animals (Albritton, et al). There ar several factors influencing concentrations of ozone. nigh of these atomic number 18 graphic, which appear to ca ingestion small fry fluctuations. Some of the factors are manmade and can ca phthisis major changes to the ozone layer. hotshot natural process is large explosive volcanoes. An eruption places aerosols and atomic add 17 into the lower stratosphere. Although this can have major effect on localized weather patterns, the effect on orbicular ozone is just about insignificant and only lasts 2-3 years. Stratospheric winds and greenhouse gases are also natural influences on the ozone concentration. The variations in how much UV radiation is disposed off from the sun also affects the ozone, scarcely it is a minimum amount. Stratospheric chlorine is a major influence on the ozone and comes more often than not from manmade halocarbons.

Catalytic humiliation by stratospheric chlo rine leads to a 3% decrease in ozone per dec! ade, proven by studies done from 1978-1991 (The Ozone Layer). I will consider the manmade problems more later when I discuss chlorofluorocarbons. showtime in the early 1970s, scientists discovered two electromotive force manmade problems poignant the ozone. The... I would not use first person in the opening paragraph. In the rest he seems to limit the use of I but I would get rid of it totally. every(prenominal) in all pretty good content.
