Presentation Transcript

  1. Effects to all the non-living and living things.

  2. Ozone depletion allows the entry of UV-B radiation:

  3. More Skin Cancers Basal Cell Carcinoma Melanoma Actinic Cheilitis (Farmer's lip) Squamous Cell Carcinoma Skin Neoplasm

  4. More Eye Cataracts

  5. Weakened Immune Systems

  6. Reduced Plant Yields

  7. Damage to ocean ecosystems and reduced fishing yields

  8. More damage to plastics and other building materials

  9. Effects on Biogeochemical Cycle • Changes in Tropospheric Composition and Air Quality • Effects on Climate

  10. IMPACTS

  11. The thinning of the Ozone Layer on both South and North Poles.

  12. Shown here is the total ozone concentration over the South Pole on Sept. 14, 2011. The "hole" is designated as the area where the total ozone concentration is below 220 Dobson units (a measure of thickness) and shown in red.

  13. On Sept. 21, 2005, sea ice extent dropped to 2.05 million sq. miles, the lowest extent yet recorded in the satellite record. Incorporating the 2005 minimum, with a projection for ice growth in the last few days of this September, brings the estimated decline in Arctic sea ice to 8.5 percent per decade.
