Thinning of ozone layer essay

This ozone layer acts as a barrier protecting life on Earth from harmful ultraviolet UV radiation from the sun.

Thinning of ozone layer essay

As results of ozone depletion, the increased ultraviolet solar radiation in turn would raise the temperature of the earth and thus effect line forms as well as the environment.

Thinning of ozone layer essay

The substantial increase in the surface temperature of the earth would cause global warming at regional and global levels. Due to ozone depletion, more ultraviolet radiation is coming on the earth.

Greenhouse effect, and ozone depletion Essay

It causes skin cancer and diseases of eyes. Thinning of ozone layer allows more ultra violet radiation to reach the earth. As a result, change in climate, reduction in crop yields, disrupting marine food chains and obstructing photosynthesis is noticed.

Ultra violet radiation affects health of people; growing number of skin cancers, cataracts, genetic changes and inability of human systems to respond to infection are some of the diseases that afflict people. UV-radiation can cause skin burns, melanoma skin cancer, leukemia, breast cancer, lung cancer, photokeratitis, etc.

UV-radiation may damage the genetic material, DNA leading to mutation. UV-radiation injures plant proteins and causes depletion of chlorophylls and mutations.

The depletion of ozone layer will induce eye cancer in cattle. The depletion of ozone layer leads to the loss of various plants from terrestrial and aquatic habitats. It will reduce the crop productivity. It will bring significant changes in the climate.

Due to the depletion of ozone layer, UV-radiation may cause Green house effect changing the global energy. Due to UV exposure, phytoplankton will die, productivity will decrease, which will affect the zooplanktons consumers will race the deficit of food.

Decrease in fish population will affect the population which depends on fish. Irreversible and photo reversible type of injuries can be caused by UV radiations.

Ozone can cause lesions to plants. Fruit and vegetable yield will decline significantly leading to crop loss. Intense UV radiation can cause evaporation of surface water, decreasing soil moisture content and through stomata. Ozone reacts with fibers like cotton, nylon and polyester and dyes etc. Ozone layer depletion may lead to significant changes in the climate.

By releasing a huge quantities of ozone eaters like chlorofluorocarbons CFCsnitrous oxide and sulphur-dioxide SO, into the atmosphere, the global temperature is increasing, which may lead to melting of glaciers and ice caps, which in turn will raise the water height submerging many coastal areas.

UV rotations due to ozone layer depletion may cause Green House Effect changing the global energy. Now scientists are trying to phase out chlorofluorocarbons CFCs which cause ozone destruction.

The alkanes would rapidly react with the ozone eating chlorine atoms, thus immobilizing them.

By protecting the ozone of the stratosphere, we can protect the human beings, all plants and animals, ecosystems and finally biosphere, from destruction. How to Control it 1. Replacing CFCs by other materials which are less damaging is one approach. The studies have shown that CFCs already released persist the atmosphere for very long periods, nearly years, and continue to damage ozone layer, even if their usage is stopped forthwith.

Studies also reveal that global warming may also contribute to ozone depletion. Use of gases such as methyl bromide which is a crop fumigant is also to be controlled. Init was agreed to phase out the ozone-depleting chemicals at a Convention in Montreal.

Since then, many industrialized countries have stopped producing and using CFCs. The use of plastic foam has to be boycotted. The use of CFCs in aerosol, spray cans, egg crates etc.

Suitable procedures should be adopted to recapture the CFCs released from the air- conditioner and refrigerator servicing units. Stringent international and national laws are to be promulgated to see that ozone layer remains intact without destruction. Now the scientists are trying to phase out CFCs by injecting different alkanes ethane, propane, etc.

These alkanes are capable of capture in the chlorine radicals, responsible for ozone depletion obtained from CFCs.Essay about The Ozone Layer - The Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40km depending on latitude, just above the tropopause.

Its existence is crucial for life on earth as we know it, because the ozone layer controls the absorption of a portion of the deadly ultraviolet (UV) rays from the sun.

Ozone Depletion – Essay Example Ozone layer is a thin layer that is located within the stratosphere and contains high concentration of ozone.

It protects our planet from . Disclaimer: This essay has been submitted by a student. This is not an example of the work written by our professional essay writers. This agreement was implemented to decrease CFC levels in order to help protect the thinning ozone layer.

Clearly, ozone depletion is a dangerous problem due to possible disease outbreaks and famine as a. Ozone Essay. A thin layer of gas called atmosphere surrounds the Earth - Ozone Essay introduction. The atmosphere serves two important purposes: it is a filter for the suns dangerous ultraviolet radiation rays and keeps the heat, necessary to maintain life on earth, within the stratosphere (Vorlat ).

Essay on Depletion of Ozone Layer! Ozone is a gas in the lower level of stratosphere. It is a kind of super-charged oxygen (O 3).

It makes a layer in the atmosphere which acts as a cover to the Earth against ultraviolet radiation of the Sun. The canopy of ozone layer is with variable extent less. Know about Ozone layer depletion. Causes, effects and solutions to save this layer is explained here.
