Ozone! What don't you know?

After reading this article about the ozone, here is three things I never knew:

1. One Chlorine atom can destroy 100,000 "good" ozone molecules
2. Over exposure to UV is believed to be contributing to the increase in melanoma, one of the most fatal of all skin cancers. It is believed that the chances of getting it has at least doubled since 1990.
3. Breathing in "bad" ozone can cause a lot of health problems. Chest pain, coughing, throat irritation and congestion are just some of the symptoms. It can worsen bronchitis as well as asthma and emphysema.
