"The battle to feed humanity is over. In the 1970s the world will undergo famines . . . [AND] hundreds of millions of people [including Americans] are going to starve to death." (1968)
"Smog disasters" in 1973 might kill 200,000 people in New York and Los Angeles. (1969)
"I would take even money that England will not exist in the year 2000." (1969)
"Before 1985, mankind will enter a genuine age of scarcity . . . in which the accessible supplies of many key minerals will be facing depletion." (1976)
