Ultraviolet Radiation Ozone Layer
1,027 wordsGreenhouse Effect On a bright, cool day, most people notice the sun's rays as feeling good on their skin. By nature, many of us even try to stay on the sunny side of the street while walking. The sun is 93 million miles away from earth and its energy travels to us in moving waves called radiation. The energy becomes heat, light and other energy too. Visible sunlight allows us to see the world around us, but there is invisible sunlight, too. These rays can't be seen, but some can be felt as heat....

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...

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...

Ozone Layer Ultraviolet Rays
962 wordsThe Problem The atmospheric ozone layer protects all living things from the harmful effects of the Sun. In recent years however, much damage has been caused to the ozone layer, causing it to decrease in size. The depletion of the ozone layer has and will continue to have many detrimental effects on all living things on this planet. A thinner layer will allow more of the suns ultraviolet radiation to reach the Earths surface. In particular, it will be the increase of UV-B rays which will have the...

The Successful Conclusion of the negotiations in Montreal was widely hailed at the time as a historic even. As the protocol was the most ambitious attempt ever to combat environmental degradation on a global scale. In the 10 years since that ...

Humankind's actions on a global scale have changed not just the landscape of the Earth, but the worlds climate too. Increasingly sophisticated measurements of the worlds climate and weather systems have provided a wealth of evidence that the Earth has been getting steadily warmer.

Natural Greenhouse Effect Greenhouse Gases
1,722 wordsWhat is global warming, and how is it affecting the Earth and its inhabitants? Global Warming is sometimes referred to as the greenhouse effect. The greenhouse effect is the absorption of energy radiated from the Earths surface by carbon dioxide and other gases in the atmosphere, causing the atmosphere to become warmer. The greenhouse effect is what is causing the temperature on the Earth to rise, and creating many problems that will begin to occur in the coming decades. For the last 10, 000 yea...

Burning Fossil Fuels Average Global Temperature
1,498 wordsGreenhouse Effect The greenhouse effect is a natural phenomenon that warms the earth and enables it to support life. Without it, the average temperature on earth would be around - 18 degrees C, instead of the current + 15 degrees C a frozen wilderness. It works on the same principles as the ordinary glass garden greenhouse, where glass allows light to get in, but does not allow for the heat to get out. This makes for a much higher temperature inside the greenhouse. On a planetary scale, similar ...

Reduce The Amount Ozone Layer
1,136 wordsOzone derives from the greek word open which means to smell. It was first discovered in 1839 by Christian Friedrich Schonbein who noticed it because of its distinctive acrid smell. He discovered this at the University of Basel in Switzerland. Ozone is merely oxygen, but not the type we breath. Ozone, O 3 has three compounds while oxygen has only two. Ozone is reac- tive, meaning it does not stay still, and wants to go back to its original state, with two compounds, O 2. This is why ozone is harm...

Ozone Layer Ultraviolet Rays
1,260 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 ...

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...

Upper Atmosphere Ozone Layer
591 wordsOzone, pronounced OH Zone, is a form of oxygen that is present in the earths atmosphere in small amounts. Ozone in the upper atmosphere is a major factor in making life on earth possible. But ozone in the lower atmosphere contributes to air pollution. Ozone is used commercially in water purification process and as a bleaching agent. Ordinary oxygen molecules have two oxygen atoms, ozone has three. Ozone is produced naturally through photochemical and electric discharge reactions. Photochemical p...

899 wordsSociety has been widely addressed with the many problems that we are having in our environment today. A major problem is that of CFCs. CFC stands for Chlorofluorocarbons which are found in many of the aerosol spray cans. In December of 1973, Rowland and Molina discovered that CFCs can destroy the ozone in the stratosphere. In June 1975, the Natural Resources Defence Council (NRDC) sued the Consumers Product Safety Commission for a band of CFCs used in aerosol spray cans. United States fifth larg...

Carbon Dioxide Emissions Parts Per Million
2,377 words1. What are the Greenhouse Gases? Carbon dioxide (CO 2) is responsible for more than half the human contribution to the greenhouse effect, and concentrations have climbed steadily from around 280 parts per million at the dawn of the industrial revolution meaning 0. 028 percent of the air s volume is taken up by the gas to around 355 ppm today. As people burn oil, coal and natural gas, they release carbon that ancient plants in past geological ages absorbed and stored. 6 As cement workers process...
