It's the End of the Earth... Day

The Predictions of the End of the World, Earth Day 1970.

“Population will inevitably and completely outstrip whatever small increases in food supplies we make. The death rate will increase until at least 100-200 million people per year will be starving to death during the next ten years.”
~Paul Ehrlich, Stanford University biologist

“By…[1975] some experts feel that food shortages will have escalated the present level of world hunger and starvation into famines of unbelievable proportions. Other experts, more optimistic, think the ultimate food-population collision will not occur until the decade of the 1980s.”
~Paul Ehrlich, Stanford University biologist

“It is already too late to avoid mass starvation.”
~Denis Hayes, chief organizer for Earth Day
