An informative and illuminating interview with Carl Safina, founder of the Blue Ocean Institute on the state of the oceans, whether overfishing or carbon pollution is a greater threat, why the BP Gulf spill wasn't as bad as many thought, the value of compassion, why conservation is more important than animal rights, the true cost of coal, the internality of "externalities", why consumerism is unnatural and why he still has hope.
