The Effect Of Ozone Layer On The Environment

The third factor that plays a major role in causing skin cancer is the Ozone layer. It helps protect people from ultraviolet radiation. However, the ozone layer is shrinking and this is due to man-made products like sprays and combustion of cars that are emitted in the atmosphere. This process is allowing more ultraviolet penetration to the earth thus increasing risk of skin cancer (Bair, 1991, P. 367,368). Ultraviolet radiation are the chief causes for skin cancer because the UV radiation

The ozone is a form of oxygen that combines three oxygen atoms in each molecule. Its important because its like a filter. CFCS, also known as, chlorofluorocarbons are used to break up some of the ozone molecules

The ozone should always stay in tact to protects the earth from UV radiation, which is harmful to humans (skin cancer) and also the earth (global warming). If allowed to build up indoors, VOCs often contribute to lightheadedness, headaches, allergies and more importantly has also scientifically proven harmful to asthma sufferers. As a matter of fact, according to Professor Roy Harrison, professor of environmental health at Birmingham University, there is a body of research on VOCs in the indoor environment which links them with those kinds of symptoms - headaches and not feeling so good (news.bbc.co.uk). After proven to have negative effects on the ozone layer as well as humans, the production of CFCs was shut down and in fact it’s banned in the US. Some scientists were not convinced by the act of banning CFCs in spite of all these evidences. “Given the large economic impact of a ban — it was estimated that industries relying on CFC production generated $8 billion in business and employed 200,000 people in 1974 — several scientists in the field advocated waiting a few years for science to make more progress on the issue before making any policy decisions.” (bio.sunyorange.edu)

In the article, Browner tries to convince the reader that it is the right thing for the United States to change or revise the ozone standard that was developed in the 1970s to apply to the 1990s. She backs up this claim by stating that: “Americans want clean air. They want their children protected. They want EPA to do its job--ensuring that the air they breathe is safe and healthy” (Browner, 1997, para. 7). I also agree that this is true. Even if we have to cut back on some of the luxuries we Americans feel entitled to, if it helps to improve the health of the overall health of the

Food is a necessity to survive, however air pollution in not beneficial to vegetation. “The deposition of ozone on vegetation weakens plants and stunts their growth,

The stratosphere absorbs the UV radiations. The troposphere is the lowest part of Earth’s atmosphere.

The fact that it is extremely stable makes it possible for CFC to slowly make it way up into the stratosphere. This prolonged life in the atmosphere allows CFC to reach great altitudes where photons are more energetic. When the CFCs come into contact with these high energy photons, their individual components are freed from the whole. Because Chlorine acts as a catalyst it is able to destroy so much of the ozone layer Chlorine then initiates the breakdown of ozone and combines with a freed oxygen to create two oxygen molecules.After the reaction, chlorine will be able to begins the cycle over and over again with another ozone molecule. With this reaction, chlorine is able to destroy thousand of ozone layer. Because the ozone molecules are being broken down they are unable to absorb any ultraviolet light so we experience more intense UV radiation at the earth's

The second article is about another issue that is causing our climate to change that can be of higher risk that would be the ozone layer. Our ozone layer seems to be dimensioning it’s been said that pollution gases. Scientist have found evidence that increased pollutants in the air this study shows this comes from cars factories and these are some examples. Some of the sicknesses that occur because of this and our ozone layer not being protected could be bronchial asthma as we know this is a syndrome which can cause shortness of breath and make it difficult for one to breath, the air pollutants on health have been the focus of attention on this factor. During the years they have conducted many experimental studies these studies have shown that even the gas from diesel exhaust have been causing the upper respiratory disease and is able to control the immune system response by increasing bad side effects with animals and humans. There have been studies and during these studies that have been done they have found evidence that air pollutants can work with in the atmosphere or on human airways, this is a very strong effect on the human body. In fact, if the airways start the inflammation some pollutants start to overcome the chest making it hard to breath which would lead to allergen-induced responses. But, air pollution and with the changes in the climate would cause a human to have an effect this would be an allergic

The sunlight that reaches us is made up of two types of harmful rays: long wave ultraviolet A (UVA) and short wave ultraviolet B (UVB) There’s also a third type of ray, UVC, these are the shortest and strongest, but they are absorbed by the ozone layer and don’t typically reach the Earth ( Bianchi, J. et al. 2013). However, in many experiments UVC is used.

However, upon first glance, this deduction does not exactly correlate with the UV light fluxuation previously discussed. Recalling that emissions were slowed and ozone depletion became more gradual with the passing of key legislature around the year 1987. So, if the ozone is slowly rebuilding itself why is the skin cancer rate increasing exponentially? The answer lies in the time between exposure to harmful rays and the development of the disease itself. It often takes years, if not decades, for continual sun exposure or a severe burn to develop into a cancerous growth. With that knowledge, the correlation is clear. The increased exposure that occurred thirty years ago is behind the intense increase in cancer cases

My first reason is because of a chemical called chlorofluorocarbons (CFCs). It has a tendency to drift up to the layer of ozone gas that surrounds the Earth and break up the ozone molecules. CFCs were found in aerosol cans that sprayed substances like deodorant and hairspray and in refrigerants, fire extinguishers and solvents for cleaning. Other ozone depleting chemicals were found

We often hear, especially in the warmer months of the year, about how we ought to be protecting ourselves from UV exposure. We are told of the importance of sunscreen and keeping ourselves covered when in direct sunlight. But why is protecting ourselves from UV light so important? According to the website, Livescience.com, UV light, or ultraviolet light, is a type of electromagnetic radiation that comes from the sun. You cannot see UV rays, which may be one of the things that makes it so dangerous. UV light can be very harmful to our bodies if we are exposed to too much, in one way, specifically, by sunburning. Every day, we are partially protected from UV light by the ozone layer. Nationalgeographic.com defined the ozone layer to be “a naturally

It has been proven that the Earth’s atmosphere blocks 98.7 percent of the sun’s UV rays. The other 2.3 percent that we are exposed to, have both beneficial and harmful effects. We do need to focus on the benefits, because we have way more of them. The only harm it does to our body is skin cancer, which by being more careful we can protect from. The

Why is the ozone layer of much concern to scientists and environmentalists? The ozone layer is quite beneficial to human life and existence. The destruction of this layer has been linked to the now common health conditions such as cancers, skin conditions and cataracts among others. It is apparent that, without the ozone layer, all humanity would be lost to disease.

National Geographic wrote the article “Good Ozone, Bad Ozone”. The article is about how there are both good parts of the ozone layer and some bad parts of the ozone layer. The ozone layer is only good when the gas is high above the ground if it is not then it can be very harmful for us. The bad thing about the ozone layer is it is made up of poisonous gasses. Approximately 90 percent of the earth’s ozone is called the stratosphere. Many scientists believe that ozone layer is being destroyed due to chemicals we use. The National Geographic was motivated to write this article to educate us on how the ozone layer has a good and a bad layer. Even though, the ozone layer is helpful because it protects us from harmful ultraviolet rays. It can be bad when the layer is depleted and
