  • Methyl Bromide Uv Radiation
    627 words
    Ozone 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...

  • Acid Rain Sulfur Dioxide
    566 words
    "Acid rain" is a broad term used to describe several ways that acids fall out of the atmosphere. A more precise term is acid deposition, which has two parts: wet and dry. Wet deposition refers to acidic rain, fog, and snow. As this acidic water flows over and through the ground, it affects a variety of plants and animals. The strength of the effects depend on many factors, including how acidic the water is, the chemistry and buffering capacity of the soils involved, and the types of fish, trees,...

  • Role In The Nitrogen Cycle Nitrogen From The Atmosphere Tree
    374 words
    The nitrogen cycle is a complex biological cycle involving the recycling of usable nitrogen. If this cycle ceased to occur, all forms of life on the planet would die. All life forms, including humans, use nitrogen in compounds called amino acids. These amino acids then act as building blocks for proteins. Nitrogen, in fact, is the most abundant element in the atmosphere. Most organisms are unable to use this nitrogen from the atmosphere and rely on the nitrogen in the soil. The cycle consists of...

    THE RECREATIONAL POISON The debate is whether or not marijuana and other drugs should be legalized for personal use. The marijuana plant may serve several beneficial uses to us, but there is one use in which it is only harmful. Marijuana should not be legalized for personal use because people do not understand, or care about the effects it causes on them and the people around them. While the War on Drugs attempts to dissuade people from using drugs primarily in economic terms (Boyle, 3), I want ...
