Paul Ehrlich, our co-founder who passed away on March 13 at the age of 93, had an extraordinary impact on our living planet. His career was defined by prolific academic output and a steadfast commitment to sounding alarms about the human predicament. While he gained immense fame — and notoriety — from The Population Bomb (co-authored with his wife, Anne Ehrlich), his work spanned disciplines from entomology to the social foundations of prejudice.
