Patrick is the author of Confessions of a Greenpeace Dropout: The Making of a Sensible Environmentalist in which he wrote that, after the collapse of World Communism and the fall of the Berlin Wall, the environment movement was hi-jacked by the "political and social activists who learned to use green language to cloak agendas that had more to do with anticapitalism and antiglobalization than with science or ecology."
During his address, Patrick tells how the early environmentalists aroused public awareness which led to the cessation of US hydrogen bomb tests and then took on French atmospheric bomb testing in the Pacific. It took some years to drive these tests underground. He then moved from what he was against, to what he was in favour of. He currently is helping to promote genetically modified "Golden Rice" to help reduce world hunger.
