Essay on Ozone Depletion. Ozone Depletion Atmospheric ozone layer depletion is a serious problem currently facing the world. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists.
Ozone layer.In 1973, scientists discovered that human-produced chlorofluorocarbons (CFCs) decimate ozone when they break apart six to 25 miles above the Earth's surface (Parson 225). This ozone destruction allows the more biologically harmful ultraviolet-B rays (UV-B) to reach the Earth's surface.Essay on Ozone Layer Depletion in English The ozone layer serves as an umbrella or protective shield of the troposphere and saves the Earth’s surface from most of the ultra violet solar radiation by absorbing the ultra violet rays. It has been found that the ozone layer over the Indo-Gangetic basin is getting depleted.Essay Effects Of Ozone Depletion On Human Health. Conveniently the environment has a protective layer that stops these harmful rays, creating a liveable environment on earth. This protective layer in the atmosphere is called the ozone layer.
Stratospheric ozone layer absorbs dangerous UVB rays of the sun and this protects the earth surface from these high-energy radiation. Over the past few decades 03 layer is thinning out because of manmade pollutants, which catalyse the dissociation of 03 at a very fast rate. Major pollutants responsible for depletion of Ozone are.
The ozone layer is a natural layer of gas in the upper atmosphere that protects humans and other living things from harmful ultraviolet (UV) radiation from the sun. Although ozone is present in small concentrations throughout the atmosphere, most (around 90%) exists in the stratosphere, a layer 10 to 50 kilometres above the Earth’s surface.
The ozone layer protects living things from harmful ultraviolet rays from the sun; without the protection of the ozone layer, millions of people would develop skin cancer and weakened immune systems. Concern about a depleting ozone layer dates back to the 1970s.
Efforts to Minimize Ozone Depletion: In 1987, United Nations Convention on Ozone Lay was held in Montreal and Montreal Protocol f signed to protect the ozone layer and cut 50 per cent of CFC production. Montreal Protocol was amended in 1990 to protect ozone layer by completely phasing out CFC and development of CFC alternatives.
With less ozone in the atmosphere, more ultraviolet radiation strikes Earth, causing more skin cancer, eye damage, and possible harm to crops. The main causes of ozone depletion are chlorofluorocarbons (CFC's), such as coolants, aerosols, and fire extinguishers.
Although the earth will be able to heal itself if the CFC level continues to stay as it is, the depletion of the ozone layer is still a problem that society should be concerned with. In order for earth to repair the damage humans have posed on the ozone layer, society must take an active role.
The ozone layer is one of the most important source of protection that exists on Earth. It is a region of the stratosphere containing a high concentration of ozone, and it prevents a great amount of ultraviolet and other high-energy radiation from penetrating to the earth's surface.
This, in turn, will lead to the breakdown of ozone. Hence, CFCs are transporting agents that are responsible for damaging the ozone layer. Download Ozone Cheat Sheet PDF. Ozone Hole. The first report of depletion in O 3 layer came out in the 1980s by an atmospheric scientist in Antarctica. This was observed over the South Pole.
Not merely will a responsible contraption disposal aid to protect the ozone bed. but the cured CFC-12 from contraptions can be resold. assisting to reimburse a part of the costs of the plan and if you suspect or witness improper releases of refrigerant or other improper service patterns. you can register a study easy and anonymously by naming the Stratospheric Ozone Information Hotline at 1.
The deterioration of the ozone layer, caused by Cfcs, endangers the lives of humans'. Cfcs have a diminishing effect on the ozone layer. Furthermore, the deterioration of the ozone causes an increase of Ultraviolet (UV) radiation which can have a negative effect on human skin and eyes.
OZONE LAYER DEPLETION “A giant asteroid could hit the earth! Something else could happen! The global temperature could rise! Wakeup!”(edf.org) Science is a body of knowledge containing various streams such as physics, chemistry, biology etc. “Its sub-behavioral concept is Technology, which has made tremendous changes in the modernized world.
The term Ozone depletion is used to describe two distinct, but related, observations: a slow, steady decline, of about 3% per decade, in the total amount of ozone in the Earth's stratosphere during the past twenty years, and a much larger, but seasonal, decrease in stratospheric ozone over the Earth's polar regions during the same period. (The latter phenomenon is commonly referred to as the.
Ozone Depletion Case for ” Ignoring the Facts” Ozone forms a layer of the earth’s atmosphere that protects us from the sun’s deadly ultraviolet rays. During the last decade there has been a scare set forth by environmental enthusiasts that Chlorofluorocarbons (CFCs) destroy the ozone layer.
How can we protect the ozone layer for future generations The ozone layer starts about 12 mi. above the earth s surface and ends about 30 mi. above the surface. The ozone layer is formed by the action of sunlight on oxygen. It forms when O 2 is broken into two atoms. The atoms then attach themselves onto oxygen molecules to form the ozone layer.
