Ozone Depletion

F. Sherwood Rowland (Oct. 20) won a Nobel Prize for research demonstrating that aerosol shaving cans were destroying the ozone. If that is so, maybe somebody else can win a Nobel Prize by showing how it is that the biggest hole in the ozone is over Antarctica. Who were all those people standing outside their igloos while they shaved? It’s enough to give anybody the shivers.
