Plastics wouldn't be necessarily my main candidate here. Gray whales are not like other whales. They eat the mud in the bottom and filter it eating the invertebrate burrowers. This means that the big trofic chain of marine scavengers in soft bottoms is disturbed in some way (some way that has been undetected still) or that Eastern Pacific whales of this species have a Fukush... ehem, health, quote, quote, problem. A problem that the Atlantic gray Whales don't have for some reason, it seems.
