Advertisements: here is your essay on ozone layer depletion ozone (o3) is a triatomic form of oxygen it is found largely in the stratosphere that extends from about 6 km at the poles and 17 km at the equator to about 50 km above the earth's surface it is present in traces less than 1 [ . Of course, in the end, it did turn out that the estimates of ozone depletion were quite inaccurate--they were far too low no scientist anticipated the stunning 70% losses of ozone that appeared in the antarctic ozone hole, nor the 30% losses in ozone that appeared in the arctic. Other kinds of eye damage include pterygium (ie, tissue growth that can block vision), skin cancer around the eyes, and degeneration of the macula (ie, the part of the retina where visual perception is most acute.
Navigate health effects of ozone depletion: skin cancer introduction ozone's unique physical properties allow the ozone layer to act as our planet's sunscreen, providing an invisible filter to help protect all life forms from the sun's damaging ultraviolet (uv) rays. In a phenomenon that could contribute to climate change, the hole in the antarctic ozone layer has changed the way that waters in the southern oceans mix, scientists report. This summary is the last one between the full assessments of 1994 and 1998 on environmental effects of ozone depletion re-analysis of historical robertson-berger (rb) meter network data has now been published, and shows that the previously reported decreasing uv trends (1974-1985.
