Annotated Bibliography : Ozone Layers And Holes

People may believe that the most important environmental issues threatening our world would be human overpopulation, ocean acidification, and pollution. However we are forgetting how important every environmental issue is to our planet and the humans that populate it. Ozone depletion affects both the planet and the people. It is a very serious environmental issue that if not solved can cost us some serious loss. The depletion of our ozone layers and the creation of the ozone hole has occurred since the 1980’s, and it 's only getting worst. The ozone layer is a form of oxygen in the molecular form of O3. It is an unstable gas with a pungent odour, it is bluish and it is located in two parts of the atmosphere: the stratosphere and the

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

The author begins the article by discussing the death percentage related to air pollution and what causes the elevated levels of air pollution. Huth continues the article by pointing out that different areas have different problems related to air pollution. Finally, Huth draws attention to the fact that different countries have different solutions to the air pollution. Though this piece was written for the entire United States, the fact that air pollution can be deadly to humans is universally applicable. Though Huth is a reporter and not an environmental scientist, Huth does cite reports made by credible institutions. Though this article talks only about how air pollution is deadly and does not expand the idea to talk about other health complications, the fact that air pollution is dangerous to human health does support my claim that a reduction in air pollution will lead to a better quality of

These chemicals are eating away at our ozone layer creating a hole in our ozone layer. This hole allows light spectrum and UV radiation to enter our planet. These radiations cause problems for all living organisms. Our ozone layer is our planets’ protection from solar radiation when integrity is compromised; all living organisms are exposed to dangerous levels of radiation. Also, these UV radiations are becoming more and more dramatic. Geoengineers are examining the effect of solar light would have on the quality of life, under the ozone layer which is becoming systemically destroyed every day. The quality of life for all living organisms cannot go anywhere but down with this dangerous solar energy entering our

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,

In today’s society, more and more threats to the welfare of our earth and atmosphere are being discovered. Some world leaders dismiss these concerns, 1) because they choose to remain ignorant of the condition of the planet’s environment, 2) because it would cost them “too much money” to fix the problem, 3) because it is easier not to deal with the problem, or 4) they simply do not care. We cannot simply ignore these problems, for any of these reasons, because the longer we wait to address them, the more dire the situation becomes. The scientists who study these threats to our environment want to solve this issue. That’s what scientists do; they form a hypothesis and test every variable until they find a solution. Mario Molina studied the effects of chlorofluorocarbons (CFCs) on the ozone, finding that they aided the depletion of the ozone in earth’s upper atmosphere, just another threat to the earth’s environment.

In 1988, the National Aeronautics and Space Administration had conclusive proof products adding to the output of carbon dioxide and methane gases in the atmosphere were causing the earth to warm; and, if not stopped will make it inhabitable for human life. In the 1970’s the United States had conclusive proof that products releasing Chlorofluorocarbons into the atmosphere were causing the ozone layer to deplete; and, that if continued would be dangerous for human life. The United States took international global action, by joining the Montreal Protocol, to phase out the products producing chlorofluorocarbon and the ozone layer has been successfully replenished .

Ozone also known as O3, is a colorless toxic gas formed by three oxygen atoms. The ozone occurs in the Earth’s upper atmosphere, the stratosphere and in the lower atmosphere, the troposphere. The ozone can affect life in a good or bad way. Good ozone is in the upper atmosphere and occurs naturally, it has a protective layer that helps block harmful ultraviolet rays (EPA.Gov). Stratospheric ozone is formed naturally and it is about 6 through 30 miles above the Earth’s surface and it also reduces the amount of harmful UV rays. Bad ozone is created by chemical reactions of oxides of nitrogen (NOx) and volatile organic compounds (VOCs) (EPA.Gov). Tropospheric or ground-level ozone is what we breathe and are formed by chemical reactions of NOx and VOCs, these reactions have been viewed by the presence of heat and sunlight, resulting in higher ozone levels in the summer. The purpose of this paper is to identify the difference ozone levels in San

the ozone hole is a big issue in Australia, the hole cause a lot of trouble that Australia don’t want, the ozone cause skin disease, sun burn, fainted and more, in the past, there is no worries when you play outdoor, you don’t need to think that you or your kids will have a sun burn, or they may die with skin cancer, you don’t need to force your kids to where a hat to prevent sunburn or skin cancer. The ozone layer is harm in the industrial revolution, and when the ozone layer was broke, things change,.

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

As human beings, we need to respect the environment in which we live. This is important to greater our future and that of others to follow. Very few people realize that their daily behaviors have a direct impact on the environment, the atmosphere in particular. By emitting harmful gasses into the air on a daily basis is one of the main reasons of such climate changes. People notice such changes and yet don't do anything to help the situation. Wee don't realize the risks that such changes in temperature pose. Rather than trying to conserve gas or taking cold showers, we still go on through our daily activities reluctant to change that will in time benefit the earth. By conserving gas

Explain the paradox that ozone is considered a health hazard, yet is essential to life on Earth. Ozone is both a health hazard and vital for life on Earth because if the gas enters the lungs, or comes in contact with any living tissue, it can result in damage in that particular tissue and illness. However, ozone is important as it shields life on Earth from the sun’s dangerous rays through the form of an ozone layer, which is located 15-30km above the Earth’s surface. 3.

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.

We use all kinds of chemicals that are damaging our air. Sprays containing chlorofluorocarbons damaging ozone layer in very top part of out atmosphere. Pesticide and other chemicals use for protecting some plant might protect plants, but they are not helping to our air at all.

Air is an indispensable part of human, animal and plant lives. Without it, no organisms would be able to survive on Earth (Reference, 2017). Due to excessive human activities, air pollution has become a detrimental worldwide issue in current days (Sciencing, 2017). However, scientists have found new chemicals that can assist in improving the air quality (Phys.org, 2017). Moreover, humans are able to adopt many methods to help decrease the severity of contamination released into the earth’s atmosphere. This investigation is linked to ‘application and limitation’ in ‘science as a Human Endeavour’.
