(Studio) National Academy of Sciences committee says fluorocarbons from aerosol spray cans will almost surely have to be regulated or banned because of damage to earth's protective ozone shield.
REPORTER: Harry Reasoner

(DC) Report on ozone and effect of fluorocarbons used in aerosols on it. Recommendations of academy committee noted. [Committee chairperson Prof. John TUKEY - cites medical dangers if ozone layer weakened.] Most dangerous of all may be warming of earth's poles; isn't known what that would mean. If man stops using fluorocarbons, will take 1 or more decades for decrease of ozone to stop. (NASA (National Aeronautics and Space Administration) film shown.) Scientists say we must know effect of what we do on selves and environment before we do it.
