I remember it well.
Here are some more dooms day predictions in which scientist made back in 1970, in celebration of the first Earth Day.

“Demographers agree almost unanimously on the following grim timetable: by 1975 widespread famines will begin in India; these will spread by 1990 to include all of India, Pakistan, China and the Near East, Africa. By the year 2000, or conceivably sooner, South and Central America will exist under famine conditions….By the year 2000, thirty years from now, the entire world, with the exception of Western Europe, North America, and Australia, will be in famine.”
Peter Gunter, professor, North Texas State University
I guess Peter Gunter forgot to predict that China and India would become an economic superpower one day.
