These rays cause cancer, cataracts, and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started...
