Ozone Depletion? What is that?
Ana S. Reyes
South Texas College Ozone Depletion? How Important is that?
Earth is surrounded by an invisible shield that is 6.2 miles long; furthermore, it absorbs most ultraviolet rays that the sun casts down to the biosphere. Without this shield, also known as the ozone layer, all life on Earth would cease to exist because of the harsh rays the sun emits. An example of how the ozone protects species is when a person goes out into the sun without sunblock, they get a grisly sunburn. Therefore, the ozone layer is the sunblock for the Earth, without it all organisms will be brutally charred. Moreover, the ozone layer is depleting gradually if not rapidly because of the effects of humankind. Although many people

Ozone Layer Information
The ozone layer is especially important to beings on Earth because the ozone layer is beneficiary for sustaining all life on Earth. Most if not all people do not know that there is layer of thick molecules that form the ozone layer. Without the ozone layer oxygen would not be kept inside the Earth’s atmosphere which would not allow organisms to support life since all living things need oxygen. Additionally, when the atmosphere, also known as the ozone layer, gets depleted it will cause many abnormalities in communities. Because the ozone layer is an immense permeable membrane allowing only certain amounts of sunlight to pass through; it helps prevents a lot of the solar energy from burning Earth’s surface,

The ozone layer is the one that protects living things from the pure ultraviolet rays of the sun.

15.2) The accumulation of chlorofluorocarbons is responsible for depleting the atmospheric zone. The atmospheric zone has changed in concentration due to human activity. The CFCs release chlorine atoms which react with ozone reducing it to molecular O₂. Following chemical reactions release the chlorine which reacts with other ozone molecules in a catalytic chain reaction. The ozone layer is getting thinner and thinner as stable air at places such as Antarctica allows reaction to continue. The accumulation of CFCs has led to increased UV radiation in sunlight reaching the earth thereby decreasing ozone levels. The global temperature has increased.

When CFC molecules reach the stratosphere, the sun's radiation breaks it apart, freeing the chorine atom to destroy ozone molecules. The effect is a growing ozone hole which forms over Antarctica in October and usually lasts through mid November. During the annual ozone hole, the amount of UV radiation that reaches the Earth can double. Ozone depletion serves as a major health risk for human beings. The three primary health effects of ultraviolet radiation on human health are damage to the skin,eyes, and immune system.
Global warming has been a continuous problem that has escalated over time on our planet Earth. The main cause of global warming is because Carbon dioxide and other warming pollutants are gathering in the atmosphere and laying over it like a thick sheet as well as its effect on the ozone layer. This is trapping the sun's heat and causing the planet to grow increasingly warmer as well as a variety of other weather shifts. Over the past 50 years, Earth’s tem...

The depletion of the ozone layer has been a trending topic after it was first discovered in 1970. The ozone layer is a portion of the earth’s stratosphere which absorbs most of the sun’s UV rays hence preventing cancer and other fatal illness to the skin. It contains high concentrations of O3 and at a constant rate is being broken down and. Since 1970, it has been discovered that about 4% of the ozone layer wears off every decade and is as a result of day-to-day human activity.

Having considered both sides of the argument surrounding the Endangered Species Act, it seems logical to conclude that, despite the fact that they Endangered Species Act could stand some improvement in terms of the speed of the bureaucracy that governs it, the Act itself is quite sufficient as is as long as it is administered to the full extent of its power. There is a growing tendency in government, however, to undermine the strength of the Endangered Species Act by making decisions on when and where to apply it a political matter rather than an ecological matter (Munro, 2010). To do this is to insure that ultimately it will not just be the environment and the wile organisms that live in it that will lose, it will be mankind as well.

In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started research on "global biogeochemical cycles" as well as the effects of supersonic transport aircraft that release nitrogen oxide into the stratosphere.2 In 1974, Molina and Rowland found that human-made chlorofluorocarbons used for making foam, cleaning fluids, refrigerants, and repellents transform into ozone-depleting agents.3 Chlorofluorocarbons stay in the atmosphere for several decades due to their long tropospheric lifetimes. These compounds are carried into the stratosphere where they undergo hundreds of catalytic cycles with ozone.4 They are broken down into chlorine atoms by ultraviolet radiation.5 Chlorine acts as the catalyst for breaking down atomic oxygen and molecular ozone into two molecules of molecular oxygen.

This thinning of the gaseous layer has formed damage near the poles. This damage is technically a hole in the ozone layer. As the ozone layer gets thinner; more ultraviolet waves reach the Earth’s surface causing much destruction to humans, animals, plants and other living organisms like plankton and bacteria. Another study by National Geographic on a forest in San Bernardino National Forest, California, pathologists examined a pine tree which is damaged as a result of a thin layer of ozone above the area. Furthermore, many people, in Seringapatam, India, suffer from skin damage and skin diseases caused by exposing to the sunlight and getting sunburned as a result of ultraviolet waves reaching the
