Meeting in Helsinki last week, representatives from 86 countries said they favored a total ban on certain chlorofluorocarbons, man-made chemicals believed to be destroying the ozone, / by the end of the century at the latest. That goes far beyond the 1987 Montreal Protocol, which called for a 50% cut in CFC manufacture...
