The Most Depressing Children's Book Ever

I admit that I go through the library randomly grabbing books for the kids while we wait for storytime. But I really can't believe this is a children's book. It has the polar bears searching the garbage for food and being put in a special "polar bear jail" while they wait for winter to come again so they can feast on more seal fat. I'll take my unrealistic, no-agenda books (though it's getting harder to find those), thank you very much, to read to my under-3 set.
