“In a decade, urban dwellers will have to wear gas masks to survive air pollution... by 1985 air pollution will have reduced the amount of sunlight reaching earth by one half...” `Life’ Magazine, January 1970
“Air pollution... is certainly going to take hundreds of thousands of lives in the next few years alone.” Paul Ehrlich
