Canada - Return of sea otters to B.C. coast worth millions, but not everyone seeing the benefits, study says

The return of playful, popular sea otters to the Pacific shores of British Columbia is adding nearly $50 million a year to the province's economy despite their impact on valuable fisheries, says a study.
University of British Columbia researchers say their conclusions may apply anywhere top predators have been returned to ecosystems from which they had been eliminated.
But they warn the benefits must be evenly shared.
