The loss comes despite the U.N. ozone treaty, known as the 1987 Montreal Protocol, which has resulted in cutbacks in ozone-damaging chemicals, such as chlorofluorocarbons, halons and other, that were used in the making of refrigerators, air conditioners, fire extinguishers and even hairspray.

Although consumed in much smaller quantities than CFCs, halons posed, molecule-for-molecule, an even greater threat to the ozone layer.

And achieving this gradual recuperation -- a process that would in any event take decades -- would require eliminating all CFCs, halons, methyl chloroform, and carbon tetrachloride, as well as strictly limiting future reliance on the HCFCs.
