Ozone Depletion Ultraviolet Radiation
624 wordsIf all the ice in Antarctica melted, it would raise the level of the world's oceans by over 200 feet (60 meters). The possibility of this happening in the near term is not seriously considered by scientists, for the Antarctic icecap is currently believed to be in equilibrium. However, meteorologists studying the ramifications of global warming and the greenhouse effect expect there to be a decrease in sea levels in the short term -- a matter of decades -- of about 2 millimeters per year. This wi...

Released Into The Atmosphere Sulfur Dioxide
1,318 wordsEvery thing present in this universe is a part of environment including ourselves. Whether they are animals, living thing, or nonliving things. All of the external factors affecting an organism. These factors may be other living organisms (biotic factors) or nonliving variables (abiotic factors), such as water, soil, climate, light, and oxygen. All interacting biotic and abiotic factors together make up an ecosystem. Organisms and their environment constantly interact, and both are changed by th...

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....

Ultraviolet Radiation Nucleic Acid
1,499 words... these processes has the potential to damage the genetic material, and thus the cell. This in turn could cause cells to function poorly, causing premature aging associated with Werner syndrome. If the DNA damage happened to inactivate tumor suppressor genes or active oncogenes, it might also cause cells to grow out of control and produce cancerous tumors. In fact, there is already evidence that a faulty helicase can cause cancers. Recently a team led by geneticist James German of the New York...

The Ozone A Hole In Theory
2,446 words... 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)! These are the type of peo...

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 ...

Methyl Bromide Uv Radiation
627 wordsOzone is a form of oxygen that is a human-made pollutant in the troposphere but a naturally produced, essential component in the stratosphere, which encircles our planet some 6 to 28 miles above the surface. The stratosphere contains a layer of ozone that shields the surface from much of the ultraviolet radiation coming from the sun. If ozone was to disappear from the stratosphere Earth would be uninhabitable for most organisms. The primary cause for this substantial ozone loss is a group of com...

Piece Of Paper Oxygen Molecules
1,524 wordsIn 1839, a German scientist Christian Schonbein was a professor of chemistry at the University of Basel in Switzerland. In addition to his teaching duties, he regularly performed secret experiments in hopes of finding out which substances make up the Earth's atmosphere. So Schonbein combined and separated a number of liquids and gases. During one of these experiments, Schonbein passed an electric charge thought a glass beaker of water, be noticed a very familiar odor. He first thought it was the...

Greenhouse Gases Ultraviolet Radiation
421 wordsDiscovery of the hole in the ozone layer showed that human activity has a major impact on Earth. The destruction of ozone in the stratosphere high above the planets surface has been brought about as the result of the widespread use of chemicals, which under normal conditions are chemically inert and harmless. Ozone occurs at all levels in the atmosphere, but most of it is found in the stratosphere, between about 15 - 50 kilometres above the Earths surface. Even there it occurs in minute concentr...

Crown Of Thorns Coral Reefs
3,746 wordsCoral reefs are among the most varied and productive communities on Earth. They are found in the warm, clear, shallow waters of tropical oceans worldwide. Reefs have functions from providing food and shelter to fish and invertebrates to protecting the shore from erosion. Unfortunately, as our understanding of corals and coral reefs increases, it becomes apparent that the effects of the human population on these communities may be increasing as well. Reef-building (or hermatypic) corals are of th...

Ozone Depletion Ozone Layer
2,469 wordsThe Potential Effects of a Depleted Ozone Layer And God said, let there be light and there was light and then God saw the light, that it was good (Genesis 1: 3 - 4). Undoubtedly, light is good. Without light man could not survive. Light is the ultimate cosmic force in this universe allowing man to progress and flourish. In the form of heat, light from the sun warms the Earth. Light, also, is the single most important factor influencing the growth and development of plants. Photosynthesis, a proc...
