The Effects Of Ozone Depletion

Holes in the ozone layer are created because the atmosphere becomes filled with a bountiful amount of gasses, which humans have a large part in contributing to. As stated in the article, Fracking Contributes to Global Warming, it says that fracking is more dangerous than conventional drilling because of the fact that it releases methane gas into the atmosphere. To clarify, fracking is the process of injecting liquids at high pressures into the ground in order to extract oil or gas. This shows that with people not worrying about the effects of global warming, they are furthering global warming's destruction when drilling for oil. Furthermore, according to the article, Fracking Contributes to Global Warming, it states, “And methane is a much more potent greenhouse gas in the short term—less than 100 years—than carbon dioxide” (“Fracking Contributes to Global Warming”). What this means is that not only are people making the world hotter, but they are also destroying the atmosphere at a quicker rate. To repeat, due to people’s lack of understanding what the risks are when dealing with global warming, the world around them is deteriorating fast. If holes continue to form in the ozone layer, people’s lives and the environment will be impacted

between 65– 76 percent of the ozone harming substances from human movement, causing the Earth's temperature to ascend at its speediest rate in a large number of years. While common difference in the Earth's carbon cycle prompts a few variances in environmental carbon dioxide (CO2) levels, in general, we can see an

In the late 1970’s scientists concluded that products releasing carbonflourochloride (CFC) was causing the ozone to deplete. The ozone layer is a protective layer from the sun’s rays and depleting the ozone layer allowed the stronger, harmful to health on earth, rays to get through. International action was taken in 1987 and the Montreal Protocol came into being. It was an international treaty to phase out CFC producing products. It went into effect in 1988 and has achieved international success. Once the Montreal Protocol had been agreed to the World Health Organization released information on the harmful effects CFC’s were having on the ozone

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.

NASA states that, “In its Fourth Assessment Report, the Intergovernmental Panel on Climate Change, a group of 1,300 independent scientific experts from countries all over the world under the auspices of the United Nations, concluded there 's a more than 90 percent probability that human activities over the past 250 years have warmed our planet”. The ozone layer and a stable climate temperature are the only thing protecting life on earth from the deadly UV rays and harmful global temperature rise. All around the world today the ozone layer is constantly depleting and the overall global temperature is constantly heating up whether anyone is acknowledging it or not, but there is a cause. Ozone layer depletion and global climate change are naturally occurring events that have been extremely and negatively heightened by human life.

-CFCs destruction to the ozone layer has allowed for UV radiation from the atmosphere to warm up the earth surface temperature higher than usual which is known as the greenhouse effect which has been known to assist in the growth of global warming. This exposure has also exposed humans to harmful UV radiation which can cause cancer.

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 .

Phrases such as “climate change” and “global warming” are often thrown around on the news and in politics; however their meaning and significance was never clear to me. I enjoyed my reading of the Susan Solomon interview because, it was very informative and easy to understand. Solomon’s outstanding achievements as a female scientist are inspiring and remarkable. Her groundbreaking studies in Antarctica concerning the ozone hole, prove to us how important it is to take care of our planet. Human produced substances known as CFCs (chlorofluorocarbons) have damaged our ozone beyond repair. It is hard to believe that humans can be so careless as to destroy their own Earth. Thankfully, “the nations of the world agreed to stop producing CFCs” in 1987.

The hole in the ozone layer is one of the most pressing issues of global warming, and this issue can be directly attributed to us. Globally, the issue of the disappearing ozone layer is mainly focused on Antarctica, but “evidence of the ozone layer thinning over other parts of the Earth has also begun to appear.” (Newton 2) This sudden trend is caused by the creation of chlorofluorocarbons, hydrochlorofluorocarbons, and halons—all human manufactured substances—entering our atmosphere in overwhelming quantities—1.1 million tons annually in the 1980s (Vermishev and Danilov-Danilyan 361). As a result of this trend, the issue of the ozone layer’s depletion truly began surfacing in the 1980s, and now “A continuous natural process of the formation and depletion of ozone occurs in the stratosphere.” (Vermishev and Danilov-Danilyan

These gases also have an effect on climate change. There are two largest ozone holes over Antarctica which occurred in 2000 (29.8km2) and 2006 (29.6km2). The ozone layer over Australia (mid-latitude) is thinned which results in more UV exposure since more UV radiation is reaching earth's surface. Research shows that the ozone layer has been thinned all over the world but especially in Australia with a 5-9% of ozone depletion since 1960. The ozone layer over Antarctica has also been thinned in spring ("atmospheric meteorological conditions around Antarctica", clouds made of ice, nitric and sulfuric acid). The discovery of the existence of the Antarctic ozone due to industrial production of chlorofluorocarbons (CFCs) in 1985 leads to the Montréal Protocol12, an international agreement which has been established to eliminate the industrial production of chlorofluorocarbons in 1987. Today the ozone layer repairs itself most due to the elimination of these gases and the global warming. The Montreal Protocol is a success and is also the first treaty that reached an agreement with all the countries in the world. Scientists estimate that this treaty will be preventing over two million cases of skin cancer each year by 2030 and that in 2035 all the vast majority ozone depleting substances will be eliminated.

The ozone layer is earth's natural shield from the sun and without it we would dead. The ozone layer can never be repaired, any damage done to it is permanent. A world without the ozone layer would immediately result in no vegetation, most animals dead, surviving human flesh would be burning and leading to cancer and organ deterioration. To prevent this from happening, we need to take care of the air and work together to live in a safer environment.

Climate change is a major issue in the world. As the population increases, more resources are required to supply basic human needs. The resources such as oil, coal, and natural gas are essential in human lives. An excessive amount of these resources in the atmosphere can cause the ozone to become compacted with C2O. These resources are called fossil fuels and burning them will trap more heat in the greenhouse effect; wildfires and volcanic eruptions can also cause more C2O in the atmosphere (Weeks). The ozone currently has more carbon dioxide than it did three million years ago. It will take two decades to replace the carbon and fifty years for the weather to adapt back to its normal state.

The environment generally refers to the surrounding’s of an object or an individual. It can be in the form of the physical environment, biophysical environment, built environment, social environment and the natural environment among other forms. The natural environment refers to the naturally occurring flora and fauna together with the land on which they occupy.

The ozone layer is a specific area in the stratosphere of maximum ozone concentration. Ozone in the stratosphere forms naturally and protects us from damage that can be caused by solar radiation such as skin cancer. In the 1970s chemists discovered that certain chemicals could travel into the upper atmosphere and damage the protective ozone. Ever since this was discovered scientists, government, and citizens have been making efforts to control and reverse the damage done to the ozone. In 1987 a treaty called the Montreal Protocol on Substances That Deplete the Ozone Layer was signed by world leaders who were participating in the Vienna Convention on the Protection of the Ozone Layer. Without this protocol the abundances of chlorine would

Ozone depletion, greenhouse effect, and acid rain are man-made disasters. The ozone layer is the part of the Earth's atmosphere which contains relatively high concentrations of ozone (O3). The cause of ozone depletion is the presence of Chlorofluorocarbons (CFCs) and related halocarbons gases in the atmosphere. In the presence of Ultraviolet light, these gases dissociate, releasing chlorine atoms, which then go on to catalyze ozone destruction. The greenhouse effect, on the other hand, is a natural warming process of the earth. When the sun's energy reaches the earth some of it is reflected back to space and the rest is absorbed. The absorbed energy warms the earth's surface which then emits heat energy back toward space as longwave
