(Welsh n.d.) As a result of these harmful impacts, the Montreal Protocol has taken the liberty in phasing out the manufacturing and use of CFC’s, a prime example of evidence-based policy making. This can be seen in Appendix C, Graph 1 (from UNEP Ozone Secretariat) which depicts the deadlines for production and consumption of Ozone depleting substances such as CFCs, Halons, Methyl chloroform, HCFCs, and many more. These organic compounds, CFCs, contain carbon, chlorine, and fluorine, produced as an unstable by-product of methane and ethane. While it was revealed that these Chlorofluorocarbons are among substances which deplete the ozone layer, it was found that one of the main elements that make up CFC’s is chlorine. As their usage grew enormously over the years, it was discovered that the ultraviolet radiation at this altitude breaks down CFCs, freeing the chlorine. (Welsh…
hydrofluorocarbons. These are compounds that save the ozone layer, yet greatly contribute to the anomalistic increase of our global climate. The anomalies in the Earth’s atmosphere were first acknowledged around the end of the 20th century, when scientists discovered the harmful effects of chlorofluorocarbons that were used in commercialized products and factories. Many countries took measures to prevent further damage to our atmosphere and their efforts resulted in the creation of the Montreal…
has been increasing and now that the effects are being felt, talk of actions have been developing. With many factors associated with the cause of global warming, a single course plan does not suffice. The biggest contributor to global warming is excess greenhouse gases such as carbon dioxide. Reducing carbon emissions is the best course of action in order to prevent the problem from getting worse. Reducing the effects of global warming must come through individual contributions and changes in…
Danger of the ozone in the Air we breathe Air pollution is a sensitive topic. The air we are breathing could be the leading cause of human illnesses in the United States. The most common illnesses caused by air pollution is Lung Disease also known as Asthma .We know this is the most common illness, but what we don’t know is what or who are causing the ozone to go bad. To quote Amanda Spake, author of the article don’t Breathe The Air. “ The outdoors was once a simple prescription for good…
Destruction of Earth for Our Luxuries The world population is estimated to be 7,356, 829, 930 people and increases by 1 birth every 8 seconds (U.S.) With the world population increasing so fast there are bound to be negative effects on the environment, but we as humans could help minimize these negative effects by cutting back on our so called luxuries. Here are a few processes that are destroying earth are ozone depletion, biodiversity loss, chemical pollution, ocean acidification and…
Recently, the release of chlorofluorocarbons, or CFCs, has caused an increase in the depletion of the ozone which in turn causes an excessive amount of ultraviolet, or UV, radiation to reach the earth. According to “Health and Environmental,” “A 10% reduction in ozone could lead to as much as a 15-20% increase in UV exposure depending on the biological process being considered.” This creates a lot of problems because an increase in UV radiation creates biological effects, or health effects, in a…
overpopulation of Earth will have many harmful effects to the Earth itself and to everything that lives on its surface and in its oceans. The reason the ozone layer is slowly being deteriorated is because chlorofluorocarbons are being broken down in the atmosphere and releasing chlorine and bromine. Overpopulation will lead to an increase of these chemicals being pumped into the air by increasing the amount of people who will be using these chemicals. Chlorofluorocarbons are found in…
In the “Perceptions of Climate Change: Linking Local and Global Perceptions through a Cultural Knowledge Approach” Beatrice Crona unraveled “the complexities of local vs global perceptions around climate change,” and essentially realized that there is a big difference between actuality and perception of how climate change is affecting the world (Crona, Wutich, Brewis & Gartin, 519). Climate change is not just a local problem, it is a global nightmare. It is not only a short term snag; it…
Good afternoon, ladies and gentlemen. Climate Change is a huge drastic problem in the world and is a common political debate. This issue has definitely one obvious side. Climate Change is man made. In Australia, flashing flooding, random weather events and droughts are common and it is all due to human influence. Seventy years ago, Australia was commonly seen with nice weather. Unfortunately, Climate Change has altered everything. Climate Change is man made because of the hole in the ozone layer…
So, while chlorofluorocarbons are safe to use in the lower atmosphere, they become more harmful in the upper atmosphere and destroy the ozone layer, which gives us protection from radiation from the sun (“Energy Policy”). With damage to the ozone layer, the earth and the people that live on it become at risk of the radiation that the sun exudes. The article “Chronology: Key Events in the History of Energy Policy” says that in solution to this problem that in 1987 the United States signed “the…
