  • 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 ...

    Air Pollution Air pollution Introduction With the great concern surrounding the destruction of the earths atmosphere due to air pollution, the immediate and direct harm caused to the human body is often over shadowed. While many are aware that our careless use of hazardous chemicals and fossil fuels may leave the planet uninhabitable in the future, most over look the fact that they are also cause real damage to our bodies at this moment. Such pollutants cause damage to our respiratory system, leading to the fluctuation of the life span of an individual depending on a number of conditions. Amongst these conditions are the individuals specific geographic location, age, and life style. This pap ...

Ozone depletion is looked upon as a problem that up till now, we can not fix. Air pollution has caused this hole in the ozone layer. The ozone layer absorbs 99% of the sun's harmful energy. It prevents ultraviolet radiation from reaching the Earth's surface and the troposphere. It protects humans from sunburn, skin and eye cancer, and cataracts. It also prevents much of the oxygen in the troposphere from being converted to ozone (gas). In the mid-seventies chemists F. Sherwood Rowland and Mario J. Malian discovered CFC's were creating a global chemical time bomb by ...

    Bears Beware subject = Environmental Issues title = Bears Beware In our world today many animals and plants are loosing their fight against human intervention in their once well-balanced ecosystem. We are all aware of the extinction of the dinosaurs and the dodo birds, however most people do not realize that annually thousands of species of our flora and fauna are now becoming extinct. This on going trend is increasingly threatening our bio diversity and global ecology. To give a specific example of animal depletion I will focus on Canadian bears. The following factors are responsible for their decline. Hunting, loss of habitat, and just plain apathy on part of the public to preserve the bio ...

  • Business Ethics - 1,474 words
    Business Ethics As a corporate manager of a publicly held company, one is responsible for the interests of many different stakeholders. In the past, it has been a very common assumption and practice that corporate managers of a company should strive to act solely for the benefit of shareholders, or owners of the company. Corporate managers were trained to take any actions necessary or use any means possible to improve the bottom line; or profits, without regard to other stakeholders. As a business student at San Diego State, I had adopted this same bottom line philosophy that had been preached to me since the day of my first business class. I had bought into these teachings so wholeheartedly ...

  • Cannabis Manifesto - 1,904 words
    Cannabis Manifesto Why is it that the one plant that could save our planet from certain environmental destruction is illegal in our country? The Cannabis plant is grown legally for hemp in many countries around the world and yet the government of this country continues to view it as a dangerous plant. The prohibition of the Cannabis plant in this country is one of the greatest injustices in our history. Cannabis has been used by humans for its fibers, oils, and medical qualities for more than 10,000 years. It seems as though Cannabis was created with the basic needs of humans in mind. It can provide us with clothing, building materials, fuel, oils, food, and many other products that are curr ...

  • Car Pollution - 333 words
    Car Pollution Air Pollution "According to the United States Environmental Protection Agency, driving a car is the single most polluting thing that most of us do." This is not a new problem. In the 1950's the Los Angeles smog made head-line news. Car exhaust causes health problems. There are many solutions to the problem. Laws were enacted as long as twenty years ago to control pollution caused by cars. Since then laws have been made, such as special nozzles on gas pumps that prevent vapor from getting into the air. We also have more tests on cars to make sure cars are maintained in a way that protects our environment. In cities, laws ask that more people ride on buses, and employees that dri ...

  • Co - 410 words
    Co2 Carbon Dioxide (CO2) C arbon Dioxide (CO2) is a colorless gas, which was first discovered in 1577 by Van Helmont who detected it in the products of both fermentation and charcoal burning. CO2 is used in solid, liquid, and gas forms in a variety of industrial processes. These include: beverage carbonation, dry ice, welding and chemicals manufacturing. It is produced by the combustion of all carbonaceous fuels and can be recovered in an abundance of ways. It is widely used today as a by-product of synthetic ammonia production, fermentation, and from flue gases by absorption process. CO2 is also a product of animal metabolism and is important in the life cycles of plants and animals. It is ...

  • Conservation And Preservation Of The Pompeiian Architecture - 1,866 words
    Conservation And Preservation Of The Pompeiian Architecture The ancient Roman city of Pompeii was buried by a volcano in 79 AD. That should be enough to destroy any town, but the city's buildings were in fact protected by this coating of ash, and although it would never be inhabited again, it now bears witness to an incredible period of history. For thousands of years, the city lay virtually undisturbed, and protected from the elements and erosion. Excavations carried out over the last centuries have allowed the city to be once again buzzing with people, and even if this notion may appear romantic, the city is also affected by the elements once again, and that is a major problem. Since it wa ...

  • Corrosion And Rusting - 1,057 words
    ... Fe2+ (aq) + 2OH- Fe(OH)2 (s) The precipitate is rapidly oxidized by dissolved oxygen to form iron (III) hydroxide. 4Fe(OH)2 (s) + O2 (aq) + 2H2O (l) 4Fe(OH)3 (s) On standing, this changes to rust, a reddish brown solid. Rust is in fact hydrated iron (III) oxide with variable composition (Fe2O3 nH2O). Factors that speed up rusting 1) Presence of electrolytes Acid solutions make rusting go faster. In industrial areas where air is seriously polluted, there are high concentrations of carbon dioxide, sulfur dioxide and nitrogen dioxide. These gases dissolve in rain water to give "acid rain", which makes iron objects rust faster. Sodium chloride also makes iron rust more quickly. For exampl ...

  • Endangered Species - 634 words
    Endangered Species ENDANGERED SPECIES Endangered species are living things whose population is so reduced that they are threatened with extinction. Thousands of species are included in this category. The International Union for the Conservation of nature and Natural Resources publishes a list of threatened mammals, birds, reptiles, amphibians, and (many people dont consider them) plants. CAUSES OF EXTINCTION Millions of years before humans, extinction of living things was linked to geological and climate, the effects of which were translated into major alternation of the environment. Environmental change is still the primary cause of the extinction of animals, but now the changes are greatly ...

  • Environmental Education Standard Conflict - 1,587 words
    Environmental Education Standard - Conflict The Key to Life or Death: An Environmental Education Standard Joe woke up one morning and looked out his window. What he saw startled him: a barren landscape, a desolate land for miles, and the absence of vegetation. He got up, rubbed his eyes, and thought what he witnessed was all part of a dream. Joe walked outside, only to be thrown back by the horrendous smell of toxic chemicals, heat generated from the greenhouse effect and gruesome after effects of acid rain. There are rusted and eroded cars lying around; millions of dead ants scour the baked topsoil. His final thought, before he radioactively melted, how did this all happen? Life on earth co ...

    Evironmentalism Evironmentalism: The Next Step Broad Social Change Through Personal Commitment Introduction In the last thirty years, America has witnessed an environmental revolution. New laws like the 1963 Clean Air Act and the 1974 Safe Drinking Water Act forged new ground in political environmentalism. Social phenomena like Earth Day, organized by Dennis Hayes in 1970, and the beginning of large-scale recycling, marked by Oregon's 1972 Bottle Bill, have help change the way Americans think about the environment. As we approach the third millennium, however, we must reconsider our place on the planet and reflect on our efforts and progress towards a sustainable society. As global warming b ...

An excellent resource on maximizing your home's insulation is Home Insulation by Harry Yost. Your local library should have, if not this book, several books on insulation that will at least get you started. Beyond updating your furnace and insulating your home, consider your personal use of heat in the home. The average American household's temperature during the winter is slowly rising because of increasingly sedentary lifestyles and lighter dress. The healthier we eat and the more exercise we get, the more internal heat our bod ...

  • Fossil Fuels - 505 words
    Fossil Fuels We get energy from sunlight, wind, nuclear plants, and damns... However, most of the energy that we use comes from fossil fuels. There are three major fossil fuels: Coal, oil and natural gas. These are composed of carbon, hydrogen, nitrogen, oxygen and sulfur. Carbon is the major element in fossil fuels. We obtain energy from fossil fuels by burning them. Coal is the most abundant fossil fuel in the U.S. Yet it has a major disadvantage. It is a strong pollutant. When it is burned, it releases impurities like nitrogen and sulfur, which combine with water vapor to create "acid rain". Also, coal is a major contributor to the imbalance of the carbon cycle. When coal burns, it forms ...

  • Global Problems Affect The Modern World Todays Rapid Changes Have Made Countries More Interdependent Than Ever Before, Shrink - 437 words
    Global problems affect the modern world. Todays rapid changes have made countries more interdependent than ever before, shrinking the world into a global village. As the world grows smaller, events in any one area have a greater impact on other parts of the world. National borders do not limit the effects of pollution or environmental destruction. Even poverty in some areas affects other areas because of migration and its impact on the world economy. Three examples of global problems that affect the modern world are famine, pollution, and terrorism. Only few countries are able to produce more food than their citizens need. For the rest of the world, hunger and malnutrition are common. In dev ...
