VOC+NOx+Sunlight=O3  ­This equation creates the ozone seen in the troposphere which is the very bottom of the Earth’s  Atmosphere and it’s doing us a bad service so nearby is bad. ­We lose ozone in the stratosphere since there is an increase in UV light which has harms such as bad air, etc. Basically, more UV reaches the surface on Earth. ­We gain ozone in the troposphere since there is a decrease in UV light UV Radiation Effects ­Human exposure can cause skin cancer ­Plants can have an alter in growth and have disease resistance ­Phytoplankton will have a reduction in productivity towards primary producers ­Amphibians that have exposed eggs can lead to deformations and or birth defects. Ozone ­The stratosphere is the ozone hole. ­Every year during the spring the ozone hole causes the ozone depletion that happens all  throughout the world and people in Antarctica have it the worst since they have more of a  direction correlation to UV lights ­Biggest depletion of ozone happens during October in Antarctica since stratospheric ozone is  abundant in that area Ozone depleting substances ­Chlorofluorocarbons(CFC’s) important because it’s the main substance that causes ozone  depletion. CFC’s are a class of these compounds carbon, hydrogen, chlorine, and fluorine. ­No2(Nitrous Oxide) ­Carbon Tetrachloride(CCl4) ­Many reasons yet these are mainly predominant Response to CFC’s ­1987 Montreal Protocol with 110 countries signing and 197 eventually joined to banned CFC’s  and ozone depleting substances in relation to CFC’s.
