Life On Earth Rain Forests
1,287 wordsLong ago, the Earth had a green belt of rain forests around its middle that covered almost twelve percent of the earth's land surface. (Miller & Berry 3) Today, the rain forest covers two percent of the earth's land surface and it is declining rapidly. The following will be a description of the rain forest, factors in its destruction, and if there are any answers to slow or halt the process. "Today, as we enter the last decade of the twentieth century, we have reached a turning point; we can no ...

Chlorofluorocarbons Cfcs Nitrogen Oxides
1,336 wordsDramatic loss of ozone in the lower stratosphere over Antarctica was first noticed in the 1970 's by a research group from the British Antarctic Survey (BAS) who were monitoring the atmosphere above Antarctica from a research station. The Halley Research Station BAS research stations in the Antarctic Rumor has it that when the first measurements were taken in 1985, the drop in ozone levels in the stratosphere were so dramatic that at first the scientists thought their instruments were defective....

Depletion Of The Ozone Layer
1,370 words... portion of the ozone layer is a major concern today. The ozone layer protects us from the harmful rays of the sun; therefore it is imperative that we preserve it. Since more pollutants are produced today than ever before (because of the major increase in the population), there is a major concern that we create less pollutants to help conserve the ozone layer. In this research paper I will give vital information on how pollution affects the ozone layer and methods instituted to help the ozone...

Ozone Depletion Ozone Layer
1,344 wordsThe Earths ozone layer shields all life on the planet from the suns harmful radiation and is extremely important to all life on the planet, but we as a human race are now faced with a very important question. This question is, Is the Earths ozone layer really depleting, and if it is, is it really a threat? There is evidence that less protection from ultraviolet rays will, over time, lead to increased amounts skin cancer, cataract, and even crop damage. With cooperation with over 140 oth countrie...

Watson, head of the ozone trends panel a supporter of the CFC banning: "Probably more people would die from food as a consequence of inadequate refrigeration than would die from depleting ozone. " An environmental scientist knowingly sending 20 - 40 million people to their deaths yearly! Banning CFCs would not only kill 20 - 40 million a year it will also lower the health of the remaining living people, by causing world-wide hunger, and food-borne diseases (Howard)!

Ozone Molecules Ozone Depletion
1,052 wordsThe beginning of the CFC (chlorofluorocarbons) era started in 1928, when CFC' were invented by a Du Pont chemist. CFC' were best known as "freon's" and became famous as a safe, nonflammable refrigerant. It's invention became a great triumph when Freon took the place of sulfur dioxide or ammonia which was used as the working liquid in refrigerators. It eventually became widely used in automobile air conditioners and nontoxic propellants in aerosol cans. It's insulating properties also was used fo...

Ozone Layer Ultraviolet Rays
1,294 wordsAtmospheric ozone layer depletion is a serious problem currently facing the world. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. The ozone layer is a region of the stratosphere containing ozone, or O 3 gas. The ozone layer is essential to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light. However, industrial and domestic chemicals ...

Chlorofluorocarbons Cfcs Ozone Depleting
1,295 wordsThe ozone layer is one of the oldest things on the planet, older than any of the ancient creatures we see in our museums today. The ozone layer has provided protection for the living components under it for millions of years, and without the ozone layer, we most likely would not be here today. Our evolution would have been cut off millions of years ago without our planets ability to provide protection from the ever-harmful rays from our sun. Each year since the late 1970 s much of the protective...

Air Pollution And Ozone Part 1
1,750 wordsAir Pollution and Ozone Depletion The year is 2007. The ozone hole over Antarctica has expanded each year and has now become a severe global threat. Sometime in July several hundred large airplanes head out on a dangerous mission over the sunless Antarctic continent. Their goal: to spray 50, 000 tons of ethane into the stratosphere in an attempt to stop the ozone hole from forming as the austral spring approaches. Though it may sound like the plot for a new Arnold Schwarzenegger movie, this idea...

Millions Of Dollars Ozone Depletion
946 wordsHalon an extinguishing agent was developed after World War II for the protection of aircraft engines. Several types were developed, and several were banned and discontinued such as halon 104. Other types were halon 1202, halon 1211, halon 1301, and halon 2402, which was never widely used in the United States due to its high toxicological concerns. Halon type 1101 was widely utilized for aircraft engines. The two most common types being; halon 1301 bromotrifluoromethane, C BrF 3, which is most co...

Uv Radiation Ozone Depletion
993 wordsOur Radiant Planet- Depletion of the Ozone Layer Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms produced when upper-atmosphere oxygen molecules are split by ultra violet light. Stratospheric ozone is found in a broad band, extending generally from 15 to 35 km above the earth. Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that ...

457 wordsThe Ozone Layer Ozone layer depletion slows There is good news about the ozone layer above us. The good news about the ozone layer is not always frequent. On International Ozone Day, the report came in that the ozone levels have decreased above Montreal and other residents of southern Canada. The ozone levels have decreased to a normal level. Normal meaning the levels have dropped from the levels reported in 1980. The ozone layer is an important and fragile part of earth. If we did not have an o...

The study was conducted between January and March with the use of NASA? s high-tech ER- 2 plane. This plane is able to reach high altitudes in order to check for ozone depletion. The measurements taken by the ER- 2 concluded that the ozone above the arctic has decreased nearly 60 percent. These measurements w...

Ozone Layer Ultraviolet Radiation
1,027 wordsOzone is an important molecule in maintaining the homeostasis in the environment. Ozone, the molecule O 3, makes a layer in the stratosphere, situated 10 to 15 kilometers from the earths surface. The dioxide molecule, O 2 and Oxygen atom O, collide with each other result in the formation of Ozone, O 3. In this reaction, the molecule O 3 contains an excess of energy. Once the molecule is formed, it is not stable enough to last long. The energy-rich O 3 molecules discards the excess energy by coll...

Stratospheric Ozone Ozone Layer
2,496 wordsThe Atmospheric Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40 km depending on latitude, just above the tropopause. Its existence is crucial for life on earth as we know it, because the ozone layer controls the absorption of a portion of the deadly ultraviolet (UV) rays from the sun. UV-A rays, including wavelengths between 320 and 400 nm, are not affected by ozone. UV-C rays between 200 and 280 nm, are absorbed by the other atmospheric constituents besides...
