THE OZONE layer filters out some of the sun's ultraviolet rays, which cause cancer and cataracts as well as other damage to animals and plants.
Recently a U.N. panel of scientists disclosed that ozone depletion over the United States and other countries in the world's temperate zones now extends into the summer months. That, of course, is when ultraviolet rays are strongest and most likely to strike bare skin, to say nothing of crops that could be damaged.
