After I posted this I saw this-
Polar bears who are individual loners ganging up on a Walrus herd to get at the old and pups. Walrus' are huge creatures, bigger than Polar bears.
They are seeking out food they seldom use. Perhaps they are being starved gradually or are there some areas worse than others where polar bears are increasing or decreasing?
The idea that Griz are moving north and competing is because their food is moving too and linked to global warming also as nature re-adjusts itself.
Shoes article says Polar bears are in decline-
But it will mean a resource that is already in decline, mainly seals, will be in even greater demand as these behemoths fight it out on the frozen shores of islands that are so far north that the northern lights are actually to the south.
We're talking 74 degrees north and above, so far up there that it's really on top of the world. Until the last few years it was an endlessly frozen landscape, but warming temperatures have reduced the floating ice that normally affords polar bears a base from which to capture seals when they surface for air. Some researchers believe the giant white bears are already in decline, and face a possibly bleak future.
What is it we're supposed to believe here! This world is so wishy washy flip floppy that it seems no one wants people to know the truth. May as well stick our heads in a hole and come up for air every few months to see which way the winds blowing.
Vague and doubtful words predominate our dialogue always, as if they just do it to cover their asses and feed bafflegab as much as they can, its intention being just to keep us guessing and at each other.
Divide, stupefy and conquer.
