I watched a sad documentary last night:
Those very cute polar bears are on the extiction list !
They showed them how their "land" (ice), has been taken away from them.
Some need to swim over 300 - 500 miles just to get back to land.
If they end up in Island,, those guys just kill them
(so sad after taking that long journey).
In Canada they are moving more and more south.. we tranqualize them.. and helicopter them back to the north..... but.... they are starving up there...
No win situation.
They can't get to the rich fishy waters they once have gotten to.
Anyways, the doc wasd 1 hr long.. if you ever see it on TV.. very much worth watching ! (think it was Discovery Channel).
