The ozone layer is a deep layer in the Earth’s stratosphere that has an altitude of about 6.2 miles and contains a high concentration of ozone molecules. The ozone layer shields the entire Earth from some of the harmful ultraviolet rays that come from the sun. The Earth’s atmosphere is composed of several layers, but the layer that we live in - the “troposphere” – is where most weather occurs. Above the troposphere is the stratosphere which is where most of the effects caused by ozone holes and global warming originate. The ozone layer absorbs 97% to about 99% of the Sun’s medium-frequency ultraviolet light which could otherwise potentially harm and damage exposed life forms on the surface of the Earth. There are three main types of ultraviolet light which are produced from the Sun: UV-A radiation, UV-B radiation and UV-C radiation. UV-A has a long wavelength of about 315 to 400 nanometers from the sun and is considered a “black light” which is not strongly absorbed by the Earth’s ozone. UV-B has a medium wave length of about 315 to 280 nanometers which is mostly absorbed by the ozone layer. 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. In the...

...times as much in the southern hemisphere. The ODS (ozone depleting substances) phase out is still providing significant climate protection benefits. Greenhouse gases, CO2 emissions, climate change, and methane emissions all contribute to the depletion of the ozone layer. By phasing out CFCs, HCFCs and all other ozone depleting substances under the Montreal Protocol, more than 5 giga tons equivalent of CO2 have already been eliminated thus helping to protect our beloved ozone layer (www.grdida.no).
Since the Montreal Protocol’s inception, significant progress has been made to protect and repair the ozone layer. However, throughout the world, people, plants, and animals are still being exposed to harmful UV rays on a daily basis. We must continue to find ways to ensure that every effort is made to work toward a global solution to the depletion of the ozone layer.

The Ozone Layer Essay

- Over the years scientists have discovered the main function of the ozone layer. They have found that the ozone layer naturally shields the Earth from ultraviolet radiation that in large amounts can be harmful. When organisms are exposed to large amounts of ultraviolet radiation, the exposure can lead to DNA mutations that can cause damage to the organism and even skin cancer in humans (NOAA News). Even though the stratospheric ozone absorbs most forms of ultraviolet radiation, about half of UV-a radiation can get through, and this radiation is the type that causes sunburn, skin cancer, and eye damage (Ozone Watch)....   [tags: Struggles, Chemistry, History]

We Must Stop The Ozone Layer Essay

- Has a person ever woke up in the morning and walked outside only to find trash (i.e. a can, papers, or bags) thrown in their yard. A mess they did not make but are no responsible for cleaning up. Does not seem very fair to most people. Look at the way God may think. God looks down and sees the care his people puts into the very planet that He created for them. People burning things into the atmosphere ruining the protective ozone layer that is over the Earth. Some people do not even think that the ozone layer exists even though The United States and over 180 other countries, saw that certain chemicals were causing the layer to start breaking down....   [tags: Earth, Atmosphere, Sun, Ozone]

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. UV-A rays, including wavelengths between 320 and 400nm, are not affected by ozone. UV-C rays between 200 and 280nm, are absorbed by the other atmospheric constituents besides ozone. It is the UV-B rays, between 280 and 320nm, absorbed only by ozone, that are of the greatest concern....   [tags: Meteorology Atmosphere Research Papers]

Essay on The Ozone Layer

- The Ozone Layer In environmental science the green house effect is a common term for the role water vapor; carbon dioxide and ozone play in keeping the earth’s surface warmer than it would normally be. The atmosphere is primarily transparent to infrared radiation from the sun, which is mostly absorbed by the earth’s surface. The earth being much cooler than the sun, remits radiation most strongly at infrared wavelengths. Water vapor, carbon dioxide and ozone then absorb much of this radiation and remit a large proportion back towards the earth....   [tags: essays research papers]

The Ozone Layer and Climate Change Essay

- Since the beginning of the industrial revolution early in the nineteenth century, our ability to change the world around us has become profound. At first, the impact on our planet was almost imperceptible, but as we have grown both in number and technological capability, that influence has grown with us. Lately, the effects of our increased activity have begun to manifest themselves in a multitude of subtle, and some not so subtle ways: we have thinned the ozone layer and may now be starting to change the very climate system upon which we and all other life on Earth depend....   [tags: Global Warming Environment Environmental Papers]

Depletion of the Ozone Layer Essay

- Depletion of the Ozone Layer The atmospheric ozone layer protects all living things from the harmful effects of the Sun. In recent years however, much damage has been caused to the ozone layer, causing it to decrease in size. The depletion of the ozone layer has and will continue to have many detrimental effects on all living things on this planet. A thinner layer will allow more of the sun’s ultraviolet radiation to reach the Earth’s surface. In particular, it will be the increase of UV-B rays which will have the most negative side effects....   [tags: Papers]

- ozone layer Summary of Learning of the Ozone Experience On the 16th of September 1987, negotiators meeting in Montreal finalized a landmark in international environmental diplomacy: the Montreal Protocol on Substances That Deplete the Ozone Layer. The Successful Conclusion of the negotiations in Montreal was widely hailed at the time as a historic even. As the protocol was the most ambitious attempt ever to combat environmental degradation on a global scale. In the 10 years since that meeting in Montreal, the accord has set in motion myriad actions by national governments, international organizations, scientists, private enterprises, and individual consumers....   [tags: essays papers]

Essay on Ozone Layer Depletion

- Ozone Layer Depletion Ozone is a natural trace component of the atmosphere. It is created continuously through the action of sunlight and oxygen in the upper atmosphere. At the same time this destroyed by various reactions with other components in the air. The next result of these natural processes is the so-called ozone layer in the stratosphere at altitudes between 15 and 50 kilometers in which the concentration of the ozone is raised. Ozone is a colorless gas, a form of oxygen. However, an ordinary molecule of oxygen contains two atoms....   [tags: Papers]

Essay Ozone

- Ozone Ozone (O3) is a molecule consisting of three oxygen atoms, similar to the oxygen we breathe (O2), however oxygen consists of only two oxygen atoms. In the stratosphere, a region high up in the upper atmosphere, light rays are responsible for the breaking down of oxygen (O2), breathable oxygen into its two separate oxygen atoms. Lone oxygen atoms are markedly reactive. When a lone oxygen atom comes into contact with a breathable oxygen molecule (O2) it combines to form ozone (O3). The ozone layer is a small residual amount of ozone concentrated in a band in the upper atmosphere....   [tags: Ozone Layer Oxygen Environmental Essays]
