We use to have this conversation about the diminished kelp forest back in the 1980s. Russ Izor would bring kelp stringers from Catalina Island to try to re-plant the Palos Verdes Peninsula. At one time there was a giant Horse Shoe Kelp forest right outside of Los Angeles Harbor. As our population grows, so does the environmental footprint. Kelp beds have died correspondingly and one study found that the only thing that could survive on the sewage at Whites Point outfall was the Sea Urchin.
