This layer does absorb 97 percent to 99 percent of the high-frequency ultraviolet light of the sun which can be possibly destructive to the life on earth. More that 90 percent of the ozone within the earth’s atmosphere is existing here “comparatively high” meaning several parts/million- considerably higher than concentrations within the lower atmosphere, however, still lesser compared to the key atmospheric components. Its location is approximately 15 to 35 km above the surface of the earth in the hemispheres lower portion (Charles, 2014). This thickness varies geographically as well as seasonally.
As mentioned earlier, prevents disastrous destruction of the life on earth through absorption of the harmful incoming sun’s ultraviolet (UV) potion hence minimizing this light’s amount that reaches the surface of the earth (Paul, 2009). Such natural sunlight buffering is quite advantageous since the ultraviolet light of high energy is capable of penetrating uppermost skin layers.as a result, cells might end up damaged which is explained through sunburn as well as more threateningly, genetic material which resides within every cell (DNA or deoxyribonucleic acid) destruction. Damage of some DNA within skin cells by such ultraviolet light is associated with certain cancers development.
Observation of the ozone hall has for a long time been done with great seriousness. Images of satellite offer observers the ozone’s every day images over Antarctic region (Enviromental Protection Agency, 2010). The winter population of humans of the Antarctic comprise of researchers in several hundreds. These researchers get protection from the UV light which has increased from warm winter clothing, hence the ozone layer health effect concerns are minimal. The ozone hole’s existence as well as its increased size through 1990s up till 2006, the time when this hole was ever largest recorded, has come to be a great concern for researchers who study human activity
