Washington Gov. Jay Inslee signed an executive order this week to aid the recovery of critically endangeredsouthern resident killer whales and the Chinook salmon they eat. There are only 76 orcas left in Puget Sound, down from 98 in 1995. Their numbers have dipped due to pollution, underwater noise and disturbances from boat traffic, and lack of their favored prey. Recent deaths, particularlyamong calves, mothers and pregnant whales, appear to be driven by food scarcity.
