I want to bring up the importance of America relying less on foreign oil. However the fact that we are killing the ozone I am putting into question now. After watching Penn and Teller Bullshit it brought to light many new things. They brought up the fact that people only account for 3% of carbon emissions where the earth is responsible for 97%. I know that humans aren’t helping but to say they are the sole reason for the ozone depletion is a little presumptuous.
