  • Air Pollution - 1,546 words
    Air Pollution Air Pollution is addition of harmful substances to the atmosphere resulting in damage to the environment, human health, and quality of life. One of many forms of pollution, air pollution occurs inside homes, schools, and offices; in cities; across continents; and even globally. Air pollution makes people sick, it causes breathing problems and promotes cancer, and it harms plants, animals, and the ecosystems in which they live. Some air pollutants return to earth in the form of acid rain and snow, which corrode statues and buildings, damage crops and forests, and make lakes and streams unsuitable for fish and other plant and animal life. Pollution is changing the earth's atmosph ...

    ... ures have in fact been rising, and the years from 1987 to 1997 were the warmest ten years on record. Most scientists are reluctant to say that global warming has actually begun because climate naturally varies from year to year and decade to decade, and it takes many years of records to be sure of a fundamental change. There is little disagreement, though, that global warming is on its way. Global warming will have different effects in different regions. A warmed world is expected to have more extreme weather, with more rain during wet periods, longer droughts, and more powerful storms. Although the effects of future climate change are unknown, some predict that exaggerated weather condi ...

  • 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 ...

  • Clouded Atmosphere - 1,110 words
    Clouded Atmosphere Clouded Atmosphere The concentration of the atmosphere's main greenhouse gases specifically, carbon dioxide, methane, nitrous oxide, and water vapor, have increased significantly during the industrial age. These high concentrations are predicted to continue in the atmosphere for thousands of years to come. This increase in specially carbon dioxide, increases the infrared energy taken in by the atmosphere, and warming the earth's surface. The Global mean temperature over the past 150 years has risen between 0.3 degrees C and 0.6 degrees C. Climate changes that have been predicted are based on the continual rise in Green House Gases. These changes include changes in: increas ...

  • Deforestations Impact - 1,329 words
    Deforestations Impact PSC 391 May 1, 2000 Deforestation is the permanent destruction of indigenous forests and woodlands.(WWF) Currently, forests cover approximately one fifth of the worlds land. Forests provide us with many products we use in our everyday lives. They also provide for us in other ways such from helping stop soil erosion to providing us with medical drugs, dyes and fabrics.. Humanity depends on the survival of a healthy ecosystem and deforestation is causing many social, economic and ecological problems. Approximately 12 million hectares of forests are depleted each year. Ninety percent of the clearing occurs in the tropical rainforests. At the current rate of clearing, all t ...

  • Environmental Air Pollution - 1,263 words
    Environmental Air Pollution My views of the environment are rooted in my belief in creation. I do not believe that life on earth began spontaneously, nor do I believe that the earth is so delicately balanced. I dont believe that the earth and its ecosystem are fragile. Many radical environmentalists do, they believe man can come along, all by themselves and change everything for worse. After hundreds of millions of years, they believe that we are the last two generations of human existence. And they think we can destroy the earth all by ourselves? I simply cannot believe this view of man and his works. I refuse to believe that people, which is also a result of Creation, can destroy the best ...

  • Environmental Effects Of Global Warming - 1,713 words
    Environmental Effects Of Global Warming Environmental Effects of Global Warming The greenhouse effect and global warming are issues that are talked about by geologists all the time. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If there were no greenhouse gasses, very few rays would be absorbed and the earth would be extremely cold. When too many rays are absorbed, the earth's atmosphere starts to warm, which leads to global warm ...

    Global Warming Global Warming The beginning of the Industrial Revolution brought many new, exciting inventions into our lives to simplify our lives and made them more efficient. Such inventions included cars, household appliances and plants that burn solid waste, fossil fuels such as oil, natural gas, and coal, and wood and wood products for fuel. Before the Industrial Revolution, human activities caused very few gases to be released into the atmosphere, but now scientists say, through the burning of fossil fuels, a large population growth and deforestation, humans are affecting the mixture of gases in the atmosphere. This mixture of gases in the atmosphere is causing the worldwide problem k ...

    Global Warming English 101 October 31, 1998 Global Warming Global Warming is an important ecological issue because it has several negative effects upon our environment. Global Warming, or what has been called the Greenhouse effect, is the result of a fourfold ecological process. 1-Sunlight radiates from the sun, through space, to Earth's atmosphere. 2- The sunlight enters the atmosphere and hits Earth. Some of it turns into heat energy in the form of infrared light. The heat gets absorbed by surrounding air and land, which in turn makes it warm. 3- Infrared rays, that are remitted into the atmosphere are trapped by greenhouse gases. 4- The gas then absorbs the light and is remitted back to t ...

    Global Warming The humanity is currently facing one its biggest problem ever. Indeed, the Earth is warming and consequences might be devastating for the future generations. There is a general agreement among scientists that Earth's climate is being affected by industrial society. Industry affects global climate by releasing greenhouse gases (GHGs). The most significant GHG is carbon dioxide (CO2). While some GHGs occur naturally, others are released in the atmosphere by certain human activities such as the burning of fossil fuels, deforestation activities and some agricultural practices. These activities affect climate by increasing the so-called 'greenhouse effect'. GHGs concentrate in the ...

    Global Warming What is global warming, and how is it affecting the Earth and it's inhabitants? Global Warming is sometimes referred to as the greenhouse effect. The greenhouse effect is the absorption of energy radiated from the Earth's 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 years, the Earth's climate has been extraordinarily beneficial to mankind. Humans have prospered tremendously well under a benign atmosphere, (Bates 28). Today, however, major changes are ...

    Global Warming Greenhouse gases (chlorofluorocarbons, carbon dioxide, methane, nitrous oxide, etc.)let heat in but stop it from going back out - like a windshield in a parked car. At our current rate of creating these gases by industry, cars and burning fossil fuels, scientists predict a temperature increase of 4 to 9 degrees F by 2050. (9 degrees F separates today's average temperatures from the last ice age.) The United Nations Panel on Climate Change recommends that we immediately cut our use of fossil fuels by at least half. To prevent the current rate from increasing, we would have to cut by 60%. This same panel projects that by 2050 over a million more people dying each year from malar ...

    Global Warming (After a lot of reading and hunting around on the net, I found a great deal of information on this topic. I had never really researched on it before so wanted to make sure that calculations agreed from report to report. Most of them did so I will base my answer on these different reports. This subject is extremely interesting, scary and a bit of a shock as to how much we have abused and taken advantage of this Earth. Though progress as far as technology has been something we make use of and enjoy, we are paying for it in ways I never thought of before this subject came up in this class! Please forgive my ignorance. I am troubled that my children and their children will suffer ...

    Global Warming Global Warming, aside from pollution is one of scientists biggest concerns. Global Warming is caused by the Greenhouse effect. There are 4 steps in the Greenhouse effect. 1-Sunlight radiates from the sun, through space, to Earths atmosphere. 2- The sunlight enters the atmosphere and hits Earth. Some of it turns into heat energy in the form of infrared light. The heat gets absorbed by surrounding air and land, which in turn makes it warm. 3- Infrared rays, that are remitted into the atmosphere are trapped by greenhouse gases. 4- The gas then absorbs the light and is remitted back to the Earths surface and warms it even more. Some of the naturally occurring greenhouse gases are ...

    Global Warming Like the glass in a greenhouse, certain gases that occur naturally in the atmosphere tend to trap the sun's heat. This natural "greenhouse effect" helps keep the Earth's average temperature at a comfortable 59 Fahrenheit. Without these greenhouse gases, the Earth would be about 0 F, like a deep- frozen snowball. But human activities are causing some greenhouse gases, such as carbon dioxide, to build up in the atmosphere. Whenever we burn fossil fuels (gasoline, oil, coal or natural gas), more carbon dioxide is emitted to the atmosphere. Forest destruction and agriculture also release greenhouse gases. If we do not act to reduce our emissions of these heat-trapping gases, it is ...

    Global Warming What happens when too much carbon dioxide gets omitted into the Earths atmosphere? The condition known as Global Warming occurs. Global Warming is the rising of the Earths surface temperature due to chemicals in the atmosphere. Global Warming has many threats on the climate and even the health of the people on this planet. Some of these threats include the altering of crop seasons and even effect the way organisms survive on the planet. The first thing I think I should discuss when talking about global warming is what causes it to occur. Gases such as carbon dioxide, methane and nitrous oxide, which are known as greenhouse gases, all build up in the atmosphere of the earth. Al ...

    Global Warming Meghan McDonald McDonald 1 Mr.Hrkal OAC World Issues December 18th, 2000 Global Warming Now, for the first time in Earth's history, humans may be a decisive factor in future climate change. The actions we make towards the temperature of the earth and the depletion of the ozone layer are irreversible. A warmer future could result from present-day human activities releasing large amounts of heat-trapping gases into the air. These greenhouse gases are part of the reason for the 1F (.5C) rise in global average temperature documented over the past 100 years. If the Earth's temperature continues to rise as predicted, future global warming could happen faster than any climate change ...

    ... nal air pollution legislation appeared until the 50's. The first federal legislation appeared in 1955 when the Air Pollution Control Act was passed. In 1965 the Motor Vehicle Air Pollution Act was passed, establishing national automobile emission regulations for the first time. Then the Air Quality Act of 1967 was passed, providing funds for additional federal research and designating air quality control regions to help establish air pollution criteria. Another goal of this act was to research the cost -effectiveness relation of available engineering control techniques. Later, during the 70's National Air Quality Standards were set for the major pollutants. Primary standards were set for ...

    Life is Changing Global warming is the most urgent environmental problem the world is facing. Few, if any, trends are more important to our future than climate change caused by human activities. This change is not beneficial. This warming trend occurring because of the buildup of greenhouse gases - primarily carbon dioxide, methane, and nitrous oxide- which is a direct result of humans and the Industrial Revolution (EPA, 2000). These gasses are emitted profusely into the atmosphere by factories, cars, and many other devices. As the sun's rays hit the Earth's surface and bounce off, the gasses trap the heat. This creates the rise in temperature. These warming temperatures have many negative e ...
