More evidence showing the West Coast of America is in trouble as dozens of gray whales have been found dead in recent weeks.
Fifty-eight gray whales have been found stranded and dead so far this year in sites stretching from California to Alaska, according to the National Oceanic and Atmospheric Administration (NOAA).
Dead whales examined so far have been malnourished, and the current hypothesis is the animals failed to eat enough last year in their summering grounds in the Bering and Chukchi seas off Alaska.
Other evidence in recent years has pointed to the decline of marine species along the west coast from Mexico to Alaska.
In June last year, The Big Wobble reported hundreds of thousands of dead seabirds had been washing up along the Alaskan coast for the 4th year in a row
Common murres, an abundant North Pacific seabird, have been dying in unprecedented numbers since 2015.
It is thought millions of the little birds have died since 2015 but the true number will never be known because the majority of birds are thought to die out at sea.
The new die-off follows a massive loss of common murres in 2015, 2016, 2017 and 2018 the biggest murre die-off on record in Alaska and a precursor to near-total reproductive failures for murres in the Gulf of Alaska and Bering.

It also follows the deaths of thousands of puffins found last fall on St. Paul Island in the Pribilofs and, prior to that, mass deaths of murres and auklets along the U.S. West Coast.
In each death wave, starving birds have left emaciated carcasses, and each wave has been associated with unusually warm marine waters.
The 2017 trawl net survey found the lowest numbers of cod on record, more than 70 per cent lower than the survey found two years earlier.
The cod decline likely resulted from the blob, a huge influx of warm Pacific Ocean water that stretched — during its 2015 peak — from the Gulf of Alaska to California’s offshore waters.
