Post by J***@webtv.netPost by r***@bestweb.netPost by J***@webtv.netI can't see the Polar Bears surviving here,
unless there's a shallow lagoon nearby that
could provide an abundance of fish. ...They
would quickly over-heat if they had to chase
the pigs through the jungle.
This canard has been around here for months.
Polar bears don't over-heat any more than do
any other bears.
Incorrect... Just do a google search for: "Polar Bear Over Heat"
..They have 41/2 " of blubber, thus do not experience heat loss.
.Consequently, they over-heat very easily. ...I would imagine they
could adapt, over time... But the fake one we saw, looked like the
typical bear we see from the old coke ads. ...Jon
Please read:
"A polar bear is so well-insulated that it experiences almost no heat
loss. In addition to its insulating fur, the bear's blubber layer can
measure 4.5 inches thick.
So effective is the polar bear's insulation that adult males quickly overheat when they run.
Because polar bears give off no detectable heat, they do not show up in infrared photographs.
(Infrared film measures heat.) When a scientist attempted to photograph a
bear with such film, he produced a print with a single spot--the puff of
air caused by the animal's breath.

I'm doing a lot of learning while trying to peer into future events on
this bloody show! Anybody else getting obsessed? Yes? Thought so...
