- Acid Rain - 1,289 words
Acid Rain Pollution comes in various forms. Whether its toxic waste, CFCs, or sewage, they are all hazardous, to the earth. These can deplete the earth and its inhabitants of resources, causing a harmful change. A product of pollution is acid rain. We shall see that acidification is harmful to all forms of life. Acid rain is any form of precipitation that is polluted by sulphur dioxide (SO2), and nitrogen oxides (NOX). This acid precipitation can be in the form of rain, snow, sleet, fog, or cloud vapors. The acidity of substances dissolved in water are measured by their pH levels. Normal precipitation pH levels fall between 5.0-5.6.2 When levels fall below these numbers, then the precipitati ...

- Air Pollution Report - 1,230 words
Air Pollution Report Air pollution is a major problem facing our environment today. This dilemma is harmful to every single living creature on this planet. How can we limit the causes of air pollution? There are industrial as well as residential causes of air pollution. How can we limit the effects of air pollution? We all know it affects the environment, but do we all know it also can affect us directly? How can we control air pollution? Is the government doing its job to protect us? Air pollution can be defined as impureness of the air. Air pollution is all around us. It might not be as clearly visible in some areas as others but the fact is that air pollution is still there affecting us i ...

- Chlorofluorocarbons Cfcs - 701 words
Chlorofluorocarbons (CFCs) CFCs are a family of man-made gases used for various industrial purposes. First developed in the 1920's in the United States, CFCs have been used in large quantaties since 1950. The industrialized countries can account for over 80% of CFCs use. CFC-11 is used primarily as a propellant in aerosol cans, although its use has been phased out it is still used in the production of plastic foams. CFC-12 is used in foam production as well as cooling coals of refrigerators and air conditioners. HCFC-22 was recently introduced as a replacement for CFC-12 because of its shorter life in the atmosphere, and thus is less of an ozone depleting drug. CFC-113, methyl chloroform, an ...

... to the environment must become proactive in reducing the strain that modern civilization has on the biosphere. Parties Involved "If current levels of consumption and production continue, efficiency in the use of all resources would have to increase by more than 50% in the next four to five decades just to keep pace with the population growth." (Sustainable America, 1996:143) Technology is already making vast progress towards the goal of a more efficient society, though the general population and manufacturers have not readily accepted the implementation of such technologies. The current U.S. economy is less than 10 percent as energy-efficient as the laws of physics permit," (Sustainable ...

- Ozone Depletion Is An Environmental Problem That Many People Do Not Take As Seriously As They Should The Ozone Layer Prot - 1,074 words
Ozone depletion is an environmental problem that many people do not take as seriously as they should. "The ozone layer protects animal and plant life from the sun's harmful radiation. The depletion of the ozone layer will allow ultraviolet rays to, over time, lead to higher skin cancer rates, eye cataracts, and crop damage." At ground level, ozone, a form of oxygen, is poisonous to humans and other organisms. It causes respiratory problems and damages plants. The greatest concentration of ozone is located in a layer of air called the stratosphere, some 10 to 30 miles above the Earth's surface. About 90% of the Earth's protective ozone layer resides in this level. "The molecule, ozone, is pro ...

- Ozone Layer - 1,860 words
Ozone Layer Some scientists have proclaimed that the human race is slowly depleting the layer of ozone which protects us from ultra violet light. In reality, humans have very little control of the world in which we live. Scientific evidence has shown that there is very little depletion in the ozone layer and the contributions the human race makes towards this depletion is and always will be insignificant compared to nature. The theories of the depletion and what it would cause are flawed and contradictory. Where and when did this global killing threat begin? It all began in the mid 1960's when the United States government began pursuing super sonic transports. These would be planes which wou ...

... ough food for humans.. Farmers of the past, present and the future have and will continue to prove these assumptions wrong. Farming is the elemant that has been keeping the assumpation wrong. Farming has been around since the 8000 B.C perhaps one of the most important inventions ever made. Without farming the world would not be able to reach the present size of the human population and the for seen future. Someone must feed the hungry, with each individual requiring about 2 200 calouries per day. Farming brings food to dinner tables and is what helps us to grow. It allows humans to grow and get taught new methods of technology to aid society in the future. In the 1940's an acre of plante ...
