Stanford University biologist Paul Ehrlich, who recently passed away, was a prominent scientific voice raising alarms about population growth, world hunger, and environmental collapse. His 1968 book, "The Population Bomb," predicted widespread famine and societal breakdown, sparking both acclaim and controversy. While some predictions didn't materialize due to the Green Revolution, Ehrlich maintained that human impacts on the planet are increasingly severe. He argued for scientists to actively engage in public discourse and address critical issues like overconsumption and population control, believing it was their ethical responsibility to do so.
