...with the dramatic increase in recent years in the release of trace gases, such as chlorofluorocarbons (CFCs), methane, nitrogen oxides and especially carbon dioxide, from industrial sources, the atmosphere is undergoing strains possibly never before experienced in its history...
...Scientists predict that thinning ozone, and the resulting increase in ultraviolet radiation, will cause damage to plants and animals, as well as skin cancers and cataracts in humans. To keep a bad situation from getting worse, nations are working on an international agreement designed to phase out production of CFCs by the year...
...paralysis. Thomas Lovejoy of the Smithsonian Institution agrees, noting that societies may pay a price for doing nothing that outweighs ) the expense of prudent preparation. While the world hailed the 1987 Montreal Protocol, designed to reduce chlorofluorocarbon output, the destruction of the ozone layer continued to accelerate because of CFCs already in use. Atmospheric chemist Sherwood Rowland of the University of California at Irvine is worried that similar delays in dealing with global warming will produce a treaty that is "a perfect autopsy...
...gave added impetus to some major international initiatives. In Basel last March, 105 nations tentatively agreed to place strict curbs on international shipments of hazardous waste. Meeting in Helsinki in May, representatives of 86 countries declared their intention to phase out their production and use of ozone-destroying chlorofluorocarbons (CFCs) by the year 2000. All this is encouraging. But make no mistake: these are only the opening skirmishes in what may prove to be mankind's ultimate battle for survival. Mostafa Tolba, executive director of the United Nations Environment Program (UNEP), put the matter starkly in his keynote speech before...
...litany of environmental hazards associated with our throw-away society is old news. Deteriorating styrofoam releases chlorofluorocarbons (CFCs), resulting in serious depletion of the earth's protective ozone layer. A group of British scientists reported in 1985 that the ozone layer over Antartica had been diminished by 40 percent. Despite global agreements to curb their use, CFCs' destructive potential lasts long after they are released. And even CFC- free styromfoams are not harmless; they will clog our landfills for centuries to come...
