In this bonus scene from-The Serengeti Rules, scientist Jim Estes discovers the collapse of the kelp forest ecosystem he had once seen thriving in the 1970s. He determines how it’s caused by a ripple effect from the Pacific Northwest whaling business in the 1990s, changing the predation of orcas, thereby decimating the otter population and the kelp forest ecosystem by extension.
