Captain Paul Watson is a pioneer of environmental activism who has helmed the Sea Shepherd Conservation Society for 35 years. His involvement in environmental causes began in 1969 when he helped organize a scrappy voyage to protest the nuclear testing at Amchitka Island by the Atomic Energy Commission. He went on to co-found the Greenpeace Foundation and was heavily involved in the campaign to stop whaling. In 1977, he founded the Sea Shepherd Society, which is known for using guerrilla tactics to shut down illegal whaling, sealing and other wildlife killing at sea. He is also a prolific author.
