Ozone Depletion
Module 7 – Writing Assignment – Ozone Debate

The debate over whether or not the ozone is actually depleting or not has been a hot topic for some time. However, it becomes a hotter topic when scientists find out it is a lower level then usual. We don’t here much from the debate when it has replenished itself to some amount, which it does do during certain seasons. Between the two sides we are to take, I am basically right in the middle. I do believe what the NASA website stated about it when it said “the ozone is extremely valuable since it absorbs a range of ultraviolet energy.” However, I don’t believe that the whole issue is potentially cataclysmic. For the sake of this paper, I will take the side of their being bigger environmental issues elsewhere. One the main reasons I believe there are bigger issues is because we simply do not have enough data to back up the ozone depletion theory. The first time the ozone was even discovered was in 1839 by Swiss chemist, Christian Schonbein, but it wasn’t measured reliably until 1918 by Robert Strutt. Having only 100 years of evidence, considering how old the earth is reported to being, doesn’t make the claims that are being made valid enough to rely on them as fact, and as a problem. Another reason I don’t believe the data is reliable enough is because we are witnessing the ozone replenishing itself season after season, especially in Antarctica. Each year the ozone develops a hole in it caused the unusual atmospheric conditions that exist during the Antarctic winter. However, it fills back in again by mid-summer. Manmade Chloro-fluoro-carbons (CFCs) are capable of destroying ozone, but they aren’t the only substances that deplete the ozone from time to time. However, the Montreal Protocol was introduced about 20 years ago to limit and control the level of CFCs, and other compounds, released into the earth’s atmosphere. The NASA website states that the protocol has been a huge success, which furthers my

    The ozone layer is one of the most debated scientific subjects of the last decade. The growing problem of its depletion is being researched heavily all over the world, and methods are being researched to try and solve the problem. There have also been many debates concerning the relationship between the ozone layer and the onset of global warming. Before solutions can be developed, however, what the ozone layer actually does and what is causing it to be depleted must be understood.…

    Air pollution is the introduction into the atmosphere of chemicals, particulates, and biological matter that cause harm to humans, other living organisms, or cause damage to the natural environment. Stratospheric ozone depletion (contributed to air pollution) has long been recognized as a threat to human health as well as to the Earth’s ecosystems. The Earth is capable of cleaning itself of a certain level of pollution, but man-made pollutant have become too numerous for the Earth’s natural mechanisms to remove. We are seeing the results of this overload in the form of acid rain, smog, and the variety of health problems that can be contributed to our environment. (Godish)…

    Central idea: The ozone layer/"hole" is caused by fluct. in the environment and CFC's are little if any of the cause of ozone depletion. CFC's are very heavy, they stay close to the ground and do not affect the stratosphere. Volcano's put out approx 10X more times chlorine than man produces. Ozone Center of WA states: "The 1991 volcanic eruption of Mount Pinatubo led to temporary severe ozone depletion but recent observations have shown that ozone concentrations have returned to pre-Pinatubo levels." The change in the ozone layer is related to seasonal…

    The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion.…

    It acts as a sun block and filters out the dangerous ultra-violet rays from the sun ("The Chemistry of the Ozone Layer"). The Earth 's atmosphere is broken up into two layers that have to do with ozone ("Ozone Layer"). The troposphere is the lowest layer ("Ozone Layer"). It extends from Earth 's surface up to about ten kilometers in altitude ("Ozone Layer"). All most all human activities happen in this layer ("Ozone Layer"). The next layer is the stratosphere ("Ozone Layer"). It continues from ten kilometers to fifty kilometers above Earth ("Ozone Layer"). All most all airplanes fly in the lowest part of this layer ("Ozone Layer"). 80 percent of the protective ozone layer is in the lower stratosphere ("Ozone Loss Declining"). "Stratospheric ozone is created by the sun 's ultra-violet radiation, which splits apart molecules of oxygen producing oxygen atoms that combine with other oxygen molecules to form ozone" (Edelson 19). The Ozone Layer is most concentrated between twelve and twenty miles above Earth (Fisher 14). The Ozone Layer protects Earth from ultra-violet rays from the sun ("The Chemistry of the Ozone Layer"). Humans and most animals would not survive without the Ozone Layer to protect them (Fisher 14).…

    In the last thirty years, it has been discovered that stratospheric ozone is depleting as a result of anthropogenic pollutants. There are a number of chemical reactions that can deplete stratospheric ozone; however, some of the most significant depletion comes from the catalytic destruction of ozone by freed halogen radicals like chlorine and bromine.…

    Hole in the Ozone is a documentary film that educates its audience the relationship of ozone and chlorofluorocarbons (CFCs) and its effects to our atmosphere. Hole in the Ozone also known as Ozone Depletion or Ozone Thinning had been an issue since the 70s and 80s. Even until now, this has become one of our major environmental issues. It is surprising to know that the ozone performs a major part in protecting us from dangerous radiation that the sun emits to our planet, even though it is also part of our pollution. As discussed in the film, the atmosphere is divided into several layers by density and temperature. In the second layer of the atmosphere, there lies our good ozone. I never knew that ozone is being build up in that layer, wherein it continues to be broken apart when struck be the sun’s radiation and combined again. As the process is being repeated, the ozone layer absorbs most of the solar radiation. But as they say, too much of everything is bad. The ozone could no longer fully protect us because as the solar radiation comes in and destroys the ozone compound, human activities in the earth also cause its depletion. Chlorofluorocarbons had been developed in the 30’s. This was even considered as a perfect compound because of its perfect qualities: non-toxic, non-flammable, non-corrosive, and non-reactant. But then, scientists started to suspect this perfect compound, and later discovered that the compound is being piled up in the troposphere and is destroyed in the stratosphere. It was intriguing to know that once this compound is destroyed, it produces chlorine atoms that kill the ozone. And the scary thing I learned too is that CFC lives up 75-100 years, takes 25 years to rise in the stratosphere, and worst of all, the CFCs effect we are experiencing now are the ones which were accumulated in the past. I hope this will be put to an end or we will suffer more in the future with life-threatening diseases like…

    Ozone depletion can be caused when the balance between the natural production and destruction of the stratospheric ozone is affected (Dobson, 2005). Despite this, an5thropogewnic causes are taken as the main causes of the depletion at the moment. It is believed that the natural phenomenon causes a temporary destruction but Chlorine and Bromine released as CFCs have more effects. These Chlorofluorocarbons cause effects that cannot be reversed they cannot mix with rain drops or be destroyed by other chemicals. Chlorofluorocarbons can survive in the air for 20 to 120 years causing more destruction. When they reach the stratospheric ozone they are broken down by the ultraviolet rays therefore releasing Chlorine. Researches show that CFCs contribute to about 80% of the ozone depletion.…
