THE PROBLEM (INTRO) The poisoning of the Earth’s ozone layer is increasingly attracting worldwide concern for the global environment and the health effects of life on the Planet Earth. There is not just one particular cause for the ozone’s depletion; the accumulation of different pollutants into our ozone layer has all added up and equalled out to create a worldwide problem. There is not just one effect from the poisoning of the ozone, but instead multiple ramifications from diseases to death. The damage to the ozone is increasing with every second. There are many ways we can help reduce the problem and preserve the ozone layer.WHAT IS OZONE Ozone is a pale blue gaseous form of oxygen, in chemical form it is also known as O3. Ozone can be beneficial or harmful depending on its location in the Earth’s atmosphere. If the ozone is located in the troposphere (which extends from the surface of the Earth up to approxiametly10 miles) it is a harmful pollutant and a major component in smog and other environmental health problems. Troposphere ozone can damage plastic, rubber, plant and animal tissue. Ozone located approximately 10-25 miles above the Earth’s surface; in a part of the Earth’s atmosphere called the
The Clean Air Act Amendments of 1990 was amended to control ozone depleting chemicals in the United States. The Antarctica Protocol bans mining for a minimum of 50 years and designates the whole continent and its marine ecosystem as a "natural reserve devoted to peace and science" (www. Avoid buying all products that contain Ozone depleting substances such as: carbon tetrachloride"tms in dry-cleaning agents, halons found in fire extinguishers, methyl chloroform in degreasers and propellants, and anything insulated in Styrofoam. Through the direct effect of exposure to ultraviolet radiation and the indirect effects on the limited food species further down the chain, most animals if not all would be doomed. CONCLUSION In conclusion, the protection and conservation of our ozone is vital for the continuation of all biological systems and life forms on earth. The use of CFCs is currently banned in the United States. Even with all the laws and CFC bans, we must all contribute a little something to nurse our fragile ozone layer back to health. Chlorofluorocarbons also known as CFCs are industrially produced chemical compounds that contain the elements chlorine, fluorine, carbon, and sometimes hydrogen that will break down the protective ozone in the atmosphere. EFFECT: PLANT LIFE The depletion of the ozone layer will just as dramatically effect plants as much as it would the humans. The total value of all the ozone depleting products since 1986 exceeded 30. REASON: CFC"tmS! The depletion of the ozone is caused by many factors, but the one cause that will be elaborated on in the next paragraph is the main reason our ozone is continuously being polluted. Halons that are used in fire extinguishers contain bromine, which also depletes ozone. Any form of elemental bromine that reacts with ozone is extremely dangerous. Man-made chemicals are not the only way ozone depletion can occur; natural depletion is also a reason the ozone layer is thinning.
