black holes and gray matter. in one thousand tangos.

             
Without intervention feeding (flown-in seal meat), we’re going to lose polar bear populations to global warming. Ultimately, even flown-in food may be insufficient for some populations, assuming climate trends continue. That could mean moving low-latitude bears further north and putting more bears in zoos to preserve genetic diversity so that when the ice returns, a healthy polar bear population can be restored. “The problem for polar bears is that we might be talking hundreds or thousands of years before sea ice actually comes back in the full context of what we have today.” [photo]

“In a report that scaled up local surveys and pilot studies to national dimensions, scientists from the Smithsonian Conservation Biology Institute and the Fish and Wildlife Service estimated that domestic cats in the United States — both the pet Fluffies that spend part of the day outdoors and the unnamed strays and ferals that never leave it — kill a median of 2.4 billion birds and 12.3 billion mammals a year, most of them native mammals like shrews, chipmunks and voles rather than introduced pests like the Norway rat. The estimated kill rates are two to four times higher than mortality figures previously bandied about, and position the domestic cat as one of the single greatest human-linked threats to wildlife in the nation. More birds and mammals die at the mouths of cats, the report said, than from automobile strikes, pesticides and poisons, collisions with skyscrapers and windmills and other so-called anthropogenic causes.” That Cuddly Kitty is Deadlier Than You Think
