Stanford University biologist Paul Ehrlich, who died March 13, 2026, in Palo Alto, California, was a scientific crusader whose dire predictions about population growth, world hunger and environmental collapse made headlines and sparked controversy for decades.
Sometimes called a “prophet of doom” by his detractors, Ehrlich was among the most public figures of the environmental movement. He was admired and often honored for his prophetic warnings. But he was also excoriated when his worst predictions failed to come true.
