Is there a reason for us to be concerned? Can ozone depletion really be connected to something that is truly harmful to humans? How are we directly affected by ozone depletion? How much do we actually know about the ozone and the things that are going on in the atmosphere? There are many questions that arise when talking about the ozone depletion in relation to skin cancer. Today both environmentalists and researchers alike focus on the increasingly dangerous affect that ultraviolet radiation has on present day society. In order to understand how the ozone affects us we must first understand what the ozone is. What is the ozone? The ozone’s essential duty is to protect society from harmful ultraviolet rays by acting as a filter. The ozone is a layer in the middle of the stratosphere that protects the earth from the harmful ultraviolet radiation emitted by the sun. The ozone layer acts as a shield and prevents the sun’s deadly ultraviolet rays from penetrating to the surface of the earth. The ozone layer protects humans in ways that are difficult to predict
The main reason that the ozone is depleting is because of the very nature of human activity. The ozone is being destroyed by chlorofluorocarbons. Chlorofluorocarbons, widely know as CFC’s, are a human-made chemicals that are composed of carbon, chlorine and fluorine atoms. It is the chlorine in chlorofluorocarbons that breaks down the molecule in the ozone causing it to slowly deplete. It is this man-made chemical been the main cause of ozone depletion high up in the atmosphere. There are several different types of CFCs. They were first developed in the 1930s, and since then have been widely used in refrigerators, aerosol cans and ...

...ting because it is the ozone layer that protects us from the very deadly and dangerous ultraviolet rays of the sun. It is very pertinent that our society recognizes that the ozone is thinning and that it is imperative that we take action, no matter how difficult it may be, so that the safety of future generations is ensured.

- 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.... [tags: Ozone depletion, Ozone layer, Chlorofluorocarbon]

- Introduction This term paper is situated in an area of specific health related and environmental concern: the human dimensions of global change. For about a decade now there has been growing scientific interest in the global environmental changes resulting from anthropogenic activity. However most of this research has focused on the scientific bases of environmental transformations with little attention to how human social responses are linked to global change. As a result, scientists and researchers alike are beginning to ask questions about the symbiotic relationship between human well being and physical change.... [tags: Geology]

- Sunblock Opposed to Sunscreen Through the depleting ozone layer and increasing levels of ultraviolet radiation within our atmosphere, skin cancer has risen as one of the major problems within contemporary society. Unfortunately, UV rays increase the risk of obtaining skin cancer since they permanently alter the DNA structure within our cells, creating a vast array of mutated cells. Research has shown that melanoma is considered the most serious type of skin cancer due to the development of dark spots on the skin, which develop in basal cells at the base of the epidermis caused by the exposure of ultraviolet rays....

- 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.... [tags: ultraviolet rays, ozone moleculas]

- Due to human activity, our planet has been slowly depleting over the years and has been recently increasing. The problems of global warming and climate change have risen due to the carelessness of the human population. Some of the problems happening to the planet is depletion of the ozone layer, the increase of endangered animals, and a decrease of natural resources. Many people fail to realize that our species is the reason this planet is dying. Increasing populations mean a higher demand for resources which will not be here forever....

- Environmental Risk Perception Ozone Hole Diminishing This article states that the ozone hole is diminishing. The credit for this good news is the phasing out of the ozone-depleting chemicals sponsored by the Montreal Protocol (Ozone hole diminishing, Nov). According to this article, the hole reached a peak of 25 million square kilometers, coming down from 28 in previous years since 1998 up to 2006. The article emphasizes the fact that ozone-depleting gases are still being used. The article continues by stating that according to the World Meteorological Organization, the planet will come back to pre-ozone hole conditions between 2060 and 2075 (Ozone hole diminishing, Nov)....

- Ozone Depletion and Industrial Output For years, we have heard about the ozone crisis: that because of industrialization and the lack of pollution-consciousness by our industries, governments, and academia, we have put so many environmentally harmful products into the atmosphere that our ozone – the good kind, the kind that protects us from harmful UV radiation – is becoming dangerously damaged. It is becoming thinner and developing holes, like the large hole over Antarctica. Predictions made expected the ozone hole to continue to increase and for the general thickness to get continuously thinner, so that the harmful UV rays of the sun would pass right through our atmosphere an...

- Global Effects of Ozone Depletion Ozone depletion in the earth’s atmosphere is under constant scrutiny by the American press and people. Perhaps the concern is warranted; the ozone layer protects life on earth by absorbing 97-99% of the damaging ultraviolet radiation from the sun (U.S. Environmental Protection Agency, 2006). Over the past twenty years, the stratospheric ozone has decreased approximately 3% per decade. Possible concerns have been raised about loss of polar caps, DNA damage, increased human health risks, and environmental process disturbance.... [tags: Environment Ozone Layer Essays Papers]

- The Ozone Ozone derives from the greek word ozein which means to smell. It was first discovered in 1839 by Christian Friedrick Schonbein who noticed it because of its distinctive acrid smell. He discovered this at the University of Basel in Switzerland. Ozone is merely oxygen, but not the type we breath. Ozone, O3 has three compounds while oxygen has only two. Ozone is reac- tive, meaning it does not stay still, and wants to go back to its original state, with two compounds, O2. This is why ozone isharmful.... [tags: Essays Papers]

- 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]
