Several people pointed out that Rob has picked up an old article. Whoops!
Rob Schneider reports that the hole in the ozone layer has reappeared:
Is this because the world did not indeed stop using CFC’s to the extent required to stop the hole? Or is there some other cause than CFS’s in making the hole? And if the latter, how come in the mid 1980′s was it protrayed that CFC’s was the only solution?
What does this teach us about other “there is only one answer” to problems?
