The Ozone layer is depleting due to man made chemicals we use everyday; this depletion causes an increase in the risk of someone developing skin cancer, and is potentially life-threatening. The ozone layer is a gas that protects the earth from the dangerous UV rays emitted from the sun. (Freedman, page 2934) Due to man made chemicals, the ozone layer is depleting which causes many problems for sustainable life on earth. The rays entering the earth’s stratosphere without the ozone layer will cause damage to many things, such as someone’s eyes or immune system, aquatic life, or plants. Another one of the consequences of ozone layer depletion is that it will cause an increase in the risk of developing skin cancer.
But we are depleting the amount of it that we still have with chlorofluorocarbons and other harmful gases. It blocks harmful UV radiation in the atmosphere from reaching the surface and keeps us safe from the effects of radiation exposure such as skin cancer, cataracts, sun burnt eyes, and possibly the lowering of our immune system, but it also contributes to the greenhouse gas effect and affects health if it sinks down too low to the surface. (Kimbrough 8) Having ozone is like playing with fire, we need it so badly to protect us from UV rays but it can cause damaging effects such as lowering our life expectancy if we breath is directly. In the 1920’s, chlorofluorocarbons started to be used in refrigeration. Unfortunately this was the beginning of a large problem in the atmosphere.
The ozone layer is very small and society the way it is now will keep depleting this very small ozone layer. Today society tries to be more eco-friendly but it needs to change quickly before it is too late. This project shows also what can happen if society changed drastically to a more eco friendly solution like wind power, or solar energy. The depletion of the ozone can cause global warming, cancer, mutations, sun burn, melanoma and more. “Laboratory and epidemiological studies demonstrate that UVB causes melanoma skin cancer and plays a major role in malignant melanoma development.
Although the sun's emissions of UV rays remain constant, decreases in stratospheric ozone levels cause a reduction in the Earth's protection from the sun's harmful rays. Research has recently shown that over exposure to UV-B radiation can impair the body's ability to fight off disease, in addition to causing skin cancer and a range of eye disorders. Ultraviolet radiation also deleteriously affects plant growth by reducing leaf size and the... ... middle of paper ... ...mental effects on marine life and the aquatic food chain. Further damage to the earth's 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 atmosphere, we can attempt to conserve what remains of the ozone layer and thus impede the increasing penetration of UV rays into the Earth's atmosphere and oceans.
The ozone layer is a key component to all life on earth. The ozone layer is up in the stratosphere protecting us from the harmful UV rays emitted by the sun. Without the ozone layer, detrimental effects can range from premature aging in the skin to multiple types of skin cancer. In this project, I will be discussing ozone depletion. I will be talking about ozone depletion causes, changes, effects, and the future of ozone depletion.
Human exposure to UV-B rays increases the risk of skin cancer, a weakened immune system, and cataracts. Additionally, UV-B exposure can also damage single cell organisms, terrestrial plant life, and aquatic ecosystems. UV-C has a short wave length of 280 to 100 nanometers and is completely absorbed by the ozone layer and the atmosphere. UV-C has a variety of positive uses, but the most unique is that it contributes to food, air, and water purification. For the billion years that the Earth has been here, ozone molecules in the atmosphere have protected life on Earth from the effects of ultraviolet rays that the Sun produces.
At ground level, though, high concentrations of ozone can be harmful. The Ozone Layer Ozone gas forms a layer all around the earth high in the stratosphere. It serves as a vital and effective protective barrier from the sun's ultraviolet rays. In recent years, scientists have sounded alarms internationally about the depletion of the ozone layer, citing chemical pollution as the major cause. A specific class of chemical compounds called chlorofluorocarbons (CFCs) are most often identified as ozone destroyers.
Algae are at the base of the marine food web and so damage to them can cause long lasting harm to marine ecosystems. Ozone in the stratosphere is caused by the photochemical reaction of oxygen in sunlight, and is formed in greater amounts around the tropics where sunlight is strongest. The least amount of ozone is found around the poles when they are in darkness. In the mid-1980's it was shown that measurements were showing decreasing amounts of ozone above the Antarctic. This depletion of ozone eventually became a large hole by the early 1990's, and this same series of events has recently been observed to be occurring over the arctic.
Whatever happens, we shall all be forced to live with the consequences for a very long time. The author of Ozone and Climate Change - A Beginner's Guide, Stephen J. Reid, has managed to put one of the most complex environmental problems into the simplest words. But as he has already mentioned, undoing what we have done to the ozone layer is not that simple. The ozone layer or ozonosphere is the region of the stratosphere containing relatively high concentrations of ozone, a pale blue, highly poisonous gas with a strong odor. Ozone is formed by the action of solar ultraviolet light on oxygen.
The Poisoning of Our Ozone Layer The poisoning of the Earth’s ozone layer is increasingly attracting worldwide concern for the global environment and the health effects of life on the Planet Earth. There is not just one particular cause for the ozone’s depletion; the accumulation of different pollutants into our ozone layer has all added up and equaled a worldwide problem. There is not just one effect from the poisoning of the ozone, but instead multiple ramifications from diseases to death. The damage to the ozone is increasing with every second; moreover, there are many ways we can help reduce the problem and preserve the ozone layer. Ozone is a pale blue gaseous form of oxygen, in chemical form it is also known as O3.
