In 1987, Peter Seligmann co-founded the nonprofit Conservation International (CI) — an organization that would go on to become one of the largest and most influential environmental nongovernmental organizations in the world. Earlier this year, he announced that he would step down as CEO and turn over the reigns to a new generation including M. Sanjayan. (Seligmann is staying on as chair of the board of directors). Ensia recently caught up with Seligmann in Seattle where he’s busy planning his next grand endeavor to protect nature for future generations.
