1. Effects of Ozone depletion  Increase eye cataracts  Suppression of the Immune system  Increase skin cancer  Increase eye burning  Decrease in crop yields i,e., corn, rice, soybean

2.  Damage to aquatic plants essential to ocean food webs  Breaks down plastics and other polymers  Increased global warming -ice melts increase in ocean volume -ocean front property erodes -midwest becomes desert -Canada/siberia becomes breadbaskets  Premature aging and brown spots

3. Factors that effect your exposure to the sun  Clouds, haze, pollution block some UV  Angle of the sun -equator vs. N. pole -winter vs. summer -morning vs. noon vs. evening  Altitude  Time in the sun

4. Solutions for Stratospheric Ozone  Stop producing CFCs properly recycle old CFCs  Use safe alternatives  Educate other governments for environmental policies

5. Solutions for Tropospheric Ozone  Car pool  Mass transit  Walking/biking  Buy cars with better gas milage  Alternative cars/fuels  Fill tanks in the morning or at night

6. Solutions for UV  Not going out when your shadow is less than the length of your body  Barriers – cap, clothing, sunglasses  Sun tan lotion, lip balm - > spf 15  No sun tanning beds  Identify skin type

7. Warning signs a mole might be malignant  Change in color, shape, or size  Oozing  Won’t heal

8. Effects of solar UV radiation on cells  Organisms have developed ways to repair damaged DNA from UV  UV sensitive yeast can be used to test your “I Wonder” ideas.  The “repair mechanism” has been removed from specialized yeast.
