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...

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...

Naturally Occurring Million Years
630 wordsChlorine, symbol Cl, is a greenish-yellow gaseous element. In group 17 of the periodic table, chlorine is one of the halogens. The atomic number of chlorine is 17. Chlorine is a greenish yellow gas, which combines directly with nearly all elements. It is a gas at normal temperature and pressure, but because it is highly reactive it is not found as a gas in nature. Instead, it appears as naturally occurring organochlorine compounds and salts. It is commonly found as NaCl (solid or seawater). The ...

Environmental Protection Agency Ozone Depletion
1,137 wordsThe 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. His findings started research on...

Drinking Water Process Called
1,173 wordsI give the copyrights to Jens Schriver. Frank J. Horgan Filtration Plant Introduction The Frank J. horgan Filtration Plant is located Southeast of Toronto on the shores of Lake Ontario (See map). Its purpose is to provide safe drinking water to our taps by filtering the water. The water is gathered from Lake Ontario. This plant has a production capacity of 455 million litres per day to supply the residents of Toronto with drinking water. Its average production of drinking water is 355 million li...

That transparent blanket our atmosphere makes life possible. It provides the air we breathe and regulates our global temperature. And it contains a special ingredient called ozone that filters deadly solar radiation. The Atmosphere The gaseous area surrounding the planet is divided into several spherical strata separated by...

Environmental Protection Agency Clean Air Act
2,294 wordsThe poisoning of the Earth? s ozone layer is increasingly attracting worldwide concern for the global environment and the health effects of life on the Planet Earth. There is not just one particular cause for the ozone? s depletion; the accumulation of different pollutants into our ozone layer has all added up and equaled a worldwide problem. There is not just one effect from the poisoning of the ozone, but instead multiple ramifications from diseases to death. The damage to the ozone is increas...

Cell Wall Human Cells
205 wordsHow does chlorine added to drinking water kill bacteria and other harmful organisms? Why doesnt it harm us? Scientific American (Ask The Experts) The article explains that although not much is known about how chlorine kills viruses and bacteria scientists hypothesize that in bacterial cells chlorine attacks the cell wall. By attacking the cell wall of a gram-negative bacterium (gram- positive bacterium are more tolerant, but most don? t pose a threat) chlorine severely increases the permeability...
