Chlorofluorocarbon

example of bad change going on in the world. Global warming, also known as the greenhouse effect, is the gradual increase of the earth’s atmospheric temperature. This means that over time, dangerously high levels of carbon dioxide and other chlorofluorocarbons in the atmosphere have warmed the earth enough to the point where great effects are…

The Montreal Protocol on Substances that Deplete the Ozone Layer 1. Introduction to the international agreement The Montreal Protocol came into effect as a result of the Vienna Convention for the Protection of the Ozone Layer. The Convention founded ozone depletion as highly global environmental problem that required international consensus on regulating the use of CFC’s. Two years later, on September 16th 1987, the Montreal Protocol on Substances that Deplete the Ozone Layer was signed by 24…

Polymerization is the process in which small molecules combine chemically to produce a large chain-like or network molecule (www.britannica.com). Through polymerization, a polymer is produced. A large number of small molecules react to produce a small number of large molecules. The reactant of polymerization is a monomer. Monomers, meaning "one part" or "one member," are small units that make up giant molecules (Exploring Giant Molecules). The product is a polymer. There are two main types of…

an impact on stratospheric science. Meanwhile, in 1970 the National Environmental Policy Act required a shuttle program office to prepare an Environmental Impact Statement. That same year James Lovelock documented the widespread presence of chlorofluorocarbons in the Earth’s troposphere. If love lock was right, there were no chemical processes or sinks that could remove CFCs from the lower atmosphere. Rowland and Molin argued they would finally decompose under the impact of ultraviolet…

Writing about my career goals is a struggle, even after a possible eighteen years of thought. Since elementary school I have switched my career goal five times; first I wanted to be an engineer, then a biochemist, then a veterinarian, then a pharmacist, and now, an environmental scientist. Over time, I have realized that they all stem from an urge to use my scientific proficiency to make the world a better place for current and future generations. Now, I cannot think of a better way to do this…

Should the Racing Industry Be Forced To Use Biofuels? You may wonder if the racing industry should be forced to use biofuels. The racing industry is mostly for fun and sport right? Well all that fun is hurting our environment. Biofuels can help that issue. Using gas as fuel causes more air pollution and rids us of our oil which could be used for more necessary occasions and products. Yes, racing could be fun to watch or experience. But, do you really want the guilt of knowing your damaging…

Climate change endangers all sectors of our society. Human health will be impacted directly and indirectly due to the environmental changes that will occur with climate change. Ozone depletion occurs when manufactured chemicals such as chlorofluorocarbons reach the stratosphere; the UV radiation from the sun causes the release of chlorine atoms that react with the ozone. This chemical cycle causes ozone destruction that depletes the ozone layer. Ultimately, the chain reaction will affect the…

Perhaps the most vital thing to address is the difference between climate and weather, because so many people don 't know the difference. Weather is what happens on a short time scale--from day to day, while climate is more long term, and is the long term trend over hundreds to thousands of years. We are releasing tons of gases and dust particles into the earth 's atmosphere every day, and so the salient question becomes: What type of effect do these gases have on our atmosphere? Most climate…

Human Influences on Global Climate Change The earth has been around for about 4.5 billion years, and the climate has been changing throughout that time period. Most of this climate change is in a sense normal because it is due to small variations in the Earth’s orbit or due to natural influences such as solar changes or volcanic eruptions. Although the occurrence of climate change is relatively settled and accepted, some uncertainty remains as to whether humans and their ecological footprint…

The impact on the environment will rise quickly once someone purchases a 2016 Toyota Camry Hybrid.With smart Fuel Economy the Camry Hybrid offers one engine that may be a 200-horsepower, 2.5-liter hybrid 4-cylinder, mated to a customary endlessly variable transmission system.Hybrid cars even have a big negative impact on the surroundings. The hybrids use nickel metal binary compound batteries that are not like conventionally vehicles. The nickle metal battery is more toxic than lead batteries,…
