  1. Ozone Layer Depletion Mathew Mokhtarzadeh, Yusei Koizumi, Alex Kim, Justin Kim

  2. What is Ozone? • Ozone is a molecule • made of 3 atoms of oxygen • Ozone is a bluish gas • Ozone helps absorbs harmful UV radiation from the sun

  3. What is the Ozone Layer? • Layer of ozone found in the stratosphere • Discovered in 1913 by French physicists Charles Fabry and Henri Buisson • Ozone layer created by oxygen-ozone cycle

  4. Importance of Ozone Layer • Protects organisms from harmful UV rays. • keeps the surface from heating up

  5. UV Rays • 3 types of UV rays • UV A rays are the least harmful • UV B rays can cause skin cancer/genetic problems • UV C rays completely are blocked

  6. What is Ozone Layer Depletion? • Deterioration of ozone layer • CFCs are the main agents • Chlorine and Bromine • More UV rays reach the surface

  7. Importance of Ozone Layer Depletion • Without the ozone layer surface heats up • Change climate • More UV rays reach Earth • Cause more genetic diseases • Effect ecosystems

  8. Causes of Ozone Layer Depletion • ODS are Ozone depleting substances • CFC are the main chemical that breaks down Ozone Layer • HCFC and PCB and halons • Volcanic Activity, Green House Gasses, and Sun Spot cycles

  9. Solutions • Decrease the use of products that contain CFC • Planting Trees • Avoid Deforestation • Check the leakage of vehicle air • Decrease emissions of chlorine, bromine, • Raise awareness of ozone layer depletion • Help pass laws that regulate emissions of harmful pollutants

  10. Current progress or laws? • Vienna Convention for the Protection of the Ozone Layer • Montreal Protocol • Annual RAD reports • Phase-out Management Plans

  11. Contacts • National Oceanic and Atmospheric Administration http://www.noaa.gov/ • National Aeronautics and Space Administration http://www.nasa.gov/ • Environmental Protection Agency http://www.epa.gov/
