The Native Americans, living along the coast of California, were fully aware of the destructive nature of the Sea Otter. They "controlled" the population of Sea Otters to minimize the destruction, but not to the point of extinction. They were smart. However, the recent attempts to re introduce otters into eco systems that will be devastated, is completely fueled by corrupt lying, paid off assholes that are greedy. "Friends of the Sea Otter", the Sierra club etc.. pay big bucks. The people that witness the destruction are dismissed and ridiculed.
