The dangers of the depletion of the ozone layer
How ozone depletion affects uv levels depletion of the ozone layer has consequences on humans, animals and plants this typically results from higher uv levels reaching us on earth humans research confirms that high levels of uv rays cause non-melanoma skin cancer additionally, it plays a major role in malignant melanoma development. The danger to which we are referring is ozone depletion there are different layers surrounding the earth’s atmosphere, including the troposphere in which nearly all human activity takes place (altitude of up to 6 miles), and the stratosphere which extends between 6 to 31 miles from the planet’s surface. The major cause of depletion of ozone layer or formation of holes are certain locations in ozone layer are chlorofluorocarbons (cfcs) and halons, which are mostly used in air conditions, refrigerators, aerosol, electric and metal clearing, foam blowing and modern fire fighting. Ozone depletion is a crucial environmental problem on earth the growing concern over cfc production and the hole in the ozone layer is causing alarm among scientists and citizens a battle has ensued to protect earth's ozone layer in the war to save the ozone layer, and you may be at risk the. “the depletion of the ozone layer is harmful to ecosystems as well it damages crops and creates respiratory problems in humans’’ agbanusi, therefore, warned against indiscriminate deforestation and other activities that could further deplete the ozone layer, so as to protect the environment from the effects of heat radiation.
The ozone layer or ozone shield is a region of earth's stratosphere that absorbs most of the sun's ultraviolet radiation it contains high concentrations of ozone (o 3 ) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. Dangers of ozone depletion are many the cause of skin cancer is one. Suggested citation:the ozone depletion phenomenon national research council 1996 the ozone depletion phenomenon washington, dc: the national academies press doi: 1017226/9042 like an infection that grows more and more virulent, the continent-size hole in earth's ozone layer keeps getting. Ozone layer depletion is one of the most serious problems faced by our planet earth it is also one of the prime reasons which are leading to global warming ozone is a colourless gas which is found in the stratosphere of our upper atmosphere the layer of ozone gas is what which protects us from the harmful ultraviolet radiations of the sun.
The ozone layer is a belt of the naturally occurring gas ozone it sits 93 to 186 miles (15 to 30 kilometers) above earth, and serves as a shield from the harmful ultraviolet b (uvb) radiation. The main things that lead to destruction of the ozone gas in the ozone layer low temperatures, increase in the level of chlorine and bromine gases in the upper stratosphere are some of the reasons that leads to ozone layer depletion. Ozone depletion, gradual thinning of earth’s ozone layer in the upper atmosphere caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities.
Hopefully, if we learn what are the effects of ozone depletion, we will finally do something to diminish the effects of climate changeozone layer depletion indicates less protection from the dangerous uvb radiation at the surface of our planet. The antarctic ozone hole, as it came to be known, made depletion of the ozone layer a real and present danger to lawmakers and the public at large predictions of significant increases in the incidence of skin cancer resulting from continued use of cfcs spurred international action. Ozone depletion describes two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around earth's polar regions.
The dangers of the depletion of the ozone layer
Ozone layer depletion, is simply the wearing out (reduction) of the amount of ozone in the stratosphere unlike pollution, which has many types and causes, ozone depletion has been pinned down to one major human activity. Ozone layer depletion study guide by radhikareddy includes 77 questions covering vocabulary, terms and more quizlet flashcards, activities and games help you improve your grades. The ozone layer absorbs uv-b from the sun our dna (and the dna of all surface dwelling plants and animals) absorbs uv-b from the sun too so if ozone thins, more uv-b gets through cancers increase, mutations increase, and crop yields decrease.
- Scientists have identified four new man-made gases that are contributing to the depletion of the ozone layer two of the gases are accumulating at a rate that is causing concern among researchers.
- The main consequence of a depleted ozone layer is a reduction in the protection it affords against harmful ultraviolet radiation (uvb) emanating from the sun according to the environmental protection agency (epa), increased uvb radiation damages human health, plant life, marine ecosystems and.
The layer of ozone helps prevents the harmful ultraviolet rays away from entering the earth’s atmosphere ozone layer depletion over the years has resulted in ozone hole formation through which harmful radiations can now enter the atmosphere. The connection between ozone layer depletion and uvb radiation reduced ozone levels as a result of ozone depletion ozone depletiona chemical destruction of the stratospheric ozone layer beyond natural reactions stratospheric ozone is constantly being created and destroyed through natural cycles. Secondly, the ozone layer over antarctica is dramatically thinned in spring, leading to the `ozone hole’ozone depletion allows more ultraviolet radiation through to the earth ultraviolet.
