ehold cleaners and paint (Cooper, 1992, p. 296). Plastics manufacturers also used CFCs to make foam products such as seat cushions, packing materials, and insulation (Cooper, 1992, p. 296). Finally, more recently, the electronics industry found that chloroflourocarbons' chemical stability made them ideal cleaning solvents for removing dust and lint from components such as circuit boards and silicon chips (Cooper, 1992, p. 296).
By 1974, CFC production had grown from 150,000 metric tons in 1960 to more than 800,000 metric tons (Cooper, 1992, p. 296).
However, even as industry was finding new uses for CFCs during the early 1970s, scientists were beginning to link the compounds to ozone destruction (Cooper, 1992, p. 296). In 1974, Ralph Cicerone and Richard S. Stolarski of the University of Michigan began investigating the possible effects on stratospheric ozone of chlorine released by National Aeronautics and Space Administration (NASA) rockets (Cooper, 1992, p. 296). They concluded that a single atom of chlorine would destroy many thousands of
