1993 Hard Cover Fine in Fine jacket 8vo-over 7?"-9?" tall. 430 pages, illustrated. "The invention of chlorofluorocarbons in 1928 by Genreal Motors scientist Thomas Midgley, Jr.
was celebrated as a boon to humanity: CFCs made possible both the mass proliferation of air conidtioning and refrigeration. By the 1950s CFCs had found further applications: as propellants in aerosol spray cans, in the manufacture of Styrofoam, and as vital industrial solvents. Then, in 1974, after millions of tons of CFCs had been released into the Earth's atmosphere, two scientists at the University of California demonstrated that these same "safe" wonder substances had altered the fundamental chemistry of the atmosphere and had begun to erode the ozone layer; the protective shield of all life on earth."
