Question

Remember the scepticism last year when the United States banned most aerosol sprays containing chlorofluorocarbons? People found it hard to believe that squirting deodorant out of a can was jeopardizing the stratospheric ozone layer, which protects the earth from excessive ultraviolet radiation. It was like finding out that eating candy causes earthquakes.

But now almost all experts agree that ozone-eating aerosol gases do indeed rise slowly into the stratosphere, where sunlight breaks them down and releases chlorine that does in fact erode the ozone layer. Even worse, the ozone seems to be eroding much faster than originally believed. The threat has not been eliminated, only postponed, by the American ban.
