Hole in the 'Zone


It sounds like something out of a science fiction movie: CFC's assault 03, causing SOD. But this geekspeak, unfortunately comes from science fact.

Billions of human-made chemical particles, once used to power spray cans and still common in air conditioners and refrigerators, have worked their way into the atmosphere. And they're destroying the ozone layer, the natural "sunscreen" that shields us from harmful sunlight.

This chapter tells you what's happening to the ozone layer—and why it matters. You'll encounter the varied forms of solar radiation, learn how some can harm us, and get tips on being sun-smart.
