Effect of Stratospheric Ozone Depletion on Aquatic Ecosystems Essays

The Effect of Stratospheric Ozone Depletion on aquatic EcosystemsIntroduction Throughout the years, advances in technology and scientific learning commence greatly influenced our global community. Various anthropogenic factors, such as the change magnitude combustion of fossil displaces and widespread employ of manmade chemicals, have greatly affect the satellites atmosphere and its ozone layer. Ozone Depletion The stratospheric ozone layer is the Earths natural means of apology from the Suns detrimental invisible rays. Some of the chemicals more or less harmful to the ozone layer be chlorofluorocarbons, or chlorofluorocarbons. These compounds ar chemically inert gasses that, when introduced to the stratosphere, speed up the depletion of the ozone layer. The reason that these chemicals are so harmful is that after a CFC molecule is upset(a) up by UV shaft of light in the stratosphere, its Chlorine fraction is plain to react with the ozone molecules in the a tmosphere. Because Chlorine is a catalyst, it continues to react with early(a) ozone molecules cause continuous damage and depletion of the ozone, as endure be seen from the chart of CFC reactions below. As the ozone layer continues to be depleted, more harmful unseeable rays are able to penetrate the earths atmosphere and are absorbed by its surface. Although the suns emissions of UV rays remain constant, decreases in stratospheric ozone levels cause a reduction in the Earths protection from the suns harmful rays. Research has recently shown that over exposure to UV-B radioactivity can impair the bodys ability to fight off disease, in summing up to cause skin cancer and a range of eye dis gives. ultraviolet radiation in like manner deleteriously affects plant growth by reducing snap coat and the... ...mental effects on shipboard soldier life and the aquatic intellectual nourishment chain. boost damage to the earths aquatic ecosystems must be foreseeed in orde r to prevent not only the admixture of oceanic life, but also the alloy of the planet and its diverse life forms. By ceasing CFC usage and implementing substitutes, as well as through decreasing fossil fuel emissions and the chuck out of other chemicals into the atmosphere, we can attempt to conserve what remains of the ozone layer and and then impede the increasing penetration of UV rays into the Earths atmosphere and oceans. The pencil eraser of the planet and its organisms rests on the protection of the stratospheric ozone layer. If the depletion of stratospheric ozone continues, it will result in the deterioration of the phytoplankton which is an outstanding base to the aquatic food chain on which most marine and animal life depends.

Various anthropogenic factors, such as the increased combustion of fossil fuels and widespread usage of manmade chemicals, have greatly affected the planets atmosphere and its ozone layer. Ozone Depletion The stratospheric ozone layer is the Earths natural means of protection from the Suns damaging ultraviolet rays. Some of the chemicals most harmful to the ozone layer are chlorofluorocarbons, or CFCs. These compounds are chemically inert gasses that, when introduced to the stratosphere, speed up the depletion of the ozone layer. The reason that these chemicals are so harmful is that after a CFC molecule is broken up by UV radiation in the stratosphere, its Chlorine atom is free to react with the ozone molecules in the atmosphere. Because Chlorine is a catalyst, it continues to react with other ozone molecules causing continuous damage and depletion of the ozone, as can be seen from the chart of CFC reactions below. As the ozone laye r continues to be depleted, more harmful ultraviolet rays are able to penetrate the earths atmosphere and are absorbed by its surface.

Further damage to the earths aquatic ecosystems must be prevented in order to prevent not only the deterioration of oceanic life, but also the deterioration of the planet and its diverse life forms. By ceasing CFC usage and implementing substitutes, as well as through decreasing fossil fuel emissions and the release of other chemicals into the atmosphe re, we can attempt to conserve what remains of the ozone layer and thus impede the increasing penetration of UV rays into the Earths atmosphere and oceans. The safety of the planet and its organisms rests on the protection of the stratospheric ozone layer. If the depletion of stratospheric ozone continues, it will result in the deterioration of the phytoplankton which is an important base to the aquatic food chain on which most marine and animal life depends.
