FE2.7 - Kelp Worlds: Trophic Cascadia (Part 1)

How did nuclear testing accidentally reshape our understanding of food webs and marine ecology? Why did sea otters bounce back from near-extinction on some parts of the Pacific coast, but are still absent in others? We speak with Dr. Jim Estes (a godfather of the field) about a series of serendipitous events that led to the re-writing of textbook ecology. This is part one of our three-part series on kelp worlds.
