Melting of sea ice blamed as walrus carcasses discovered
Conservation charity WWF said it had obtained footage of more than 100 walrus carcasses spotted by US Geological Survey (USGS) researchers flying near Icy Cape, Alaska, after a massive herd of walruses congregated on the shore.
A preliminary report by experts in the US concluded 131 carcasses found in the area, mostly of calves and young walruses, had been trampled to death by other walruses.
