LAURA SULLIVAN, HOST:
It's WEEKENDS on ALL THINGS CONSIDERED, from NPR News. I'm Laura Sullivan.
In 2008, writer Zac Unger had a plan. He was going to save the polar bears by writing an epic treatise on the demise of the species.
ZAC UNGER: My humble plan was to become a hero of the environmental movement. I was going to go up to the Canadian Arctic; I was going to write this mournful elegy for the polar bears, at which point I'd be hailed as the next coming of John Muir, and borne aloft on the shoulders of my environmental compatriots.
SULLIVAN: There was just one problem - not all the polar bears seemed to be dying. He realized the truth about the polar bears was complicated. In the meantime, though, he and his wife and three small kids had the adventure of a lifetime: moving from Oakland, California, to Churchill, Manitoba - way up in northern Canada, on the Hudson Bay. It's flat, gray, accessible only by plane and train; and for a few months out of the year, there are as many polar bears as there are people. He details their experience in his new book, "Never Look a Polar Bear in the Eye."
UNGER: When I got up there, I started realizing that polar bears were not in as bad shape as the conventional wisdom had led me to believe, which was actually very heartening but didn't fit well with the book I'd been planning to write.
SULLIVAN: A lot of people are going to hear that and say, wait a second - all we've been told, for a decade now, is that the polar bears are going extinct, and it's our fault. And they're all dying, and the ice is shrinking, and their lives are soon going to be over.
UNGER: Well, here's a fact that kind of blew me away when I first realized it. There are far more polar bears alive today than there were 40 years ago. There are about 25,000 polar bears alive today, worldwide. In 1973, there was a global hunting ban. And so once hunting was dramatically reduced, the population exploded. So this is not to say that global warming is not real or is not a problem for the polar bears. But polar bear populations are large, and the truth is that we can't look at it as a monolithic population that is all going one way or another.
SULLIVAN: You moved your whole family up north, to do the research for this book. What was that like?
UNGER: Well, you know, the idea was to use my children as bait, of course.
UNGER: The polar bears love little kids; they're perfect snacks. But we were in this town in northern Manitoba, where polar bears - literally - will walk down Main Street. People leave their houses and their cars unlocked; and it's perfectly good form just to duck into any open door you can find, when there's a polar bear chasing you.
People use what they call Churchill welcome mats, which is a piece of plywood laid down in front of the door, or leaned up against the door, with hundreds of nails sticking out so that when the polar bear comes up to pad across your porch, he's going to get a paw full of sharp nails.
SULLIVAN: So there are literally, polar bears on the streets, walking the streets with people, from time to time.
UNGER: Well, I don't want to oversell it. There are definitely polar bears that come into town. There are polar bears that will take a swipe at garbage cans. There are polar bears that eat people's dogs. But Churchill has developed a really innovative polar bear alert program. And the way that works is, you dial a phone number - 675-BEAR - when you see a bear; and a bunch of wildlife conservation officers in a truck with a bunch of guns, come by, and they kind of scare the bears out of town. And they have a progression that they use. First, they will fire firecracker shells; then they'll move up to rubber bullets. And then, if necessary - as a last resort - move up to real bullets.
SULLIVAN: Then they'll actually kill the polar bear, if they have to.
UNGER: If they have to. That's very, very rare. They don't want to do that. These are conservation officers, so their job is to keep bears safe. Churchill also has a polar bear jail. These are for bears who keep coming into town, and can't be hazed out of town. And what they do is, they will trap these bears and put them in the polar bear jail - which is just a great big, decommissioned military building. They're given no food. They're given only snow, to drink. And they just go in there, and they wait until the bay freezes up. And when the bay freezes up, these bears can be released, to go back out on the ice. They don't want to be in town. They're just there waiting for the ice to freeze. But if they're a hassle in town - put them in jail, give them a short sentence, and the problem is resolved.
SULLIVAN: So once the bay freezes, they can go back after their natural food source.
UNGER: Right. The dominant food that they like to eat is seals, and they can only hunt seals from out on the sea ice. They can't hunt seals from shore. They need to be able to go on the ice.
SULLIVAN: It would freak me out to walk around with my kids on the street in a city, and feel like there are going to be polar bears that are going to jump out of somewhere - and grab my kid out of the stroller.
UNGER: It did freak me out. I mean, it's scary. There's no doubt about it. You know, we were up there for Halloween. And Halloween is when you're supposed to go out in the dark with lots of food, and run around with your kids. So what they do is, when you go out trick-or-treating, you go out with somebody who has a gun; either a police officer, a volunteer - you know, somebody from the military. They all come out, and they help you go trick-or-treating. Now, they have one rule, which is that kids can't dress in anything white - no princesses, no ghosts - because you don't want to be dressed as something white in the darkness, when there's a bunch of guys with guns looking for polar bears.
SULLIVAN: Zac Unger is the author of "Never Look a Polar Bear in the Eye: A Family Field Trip to the Arctic's Edge in Search of Adventure, Truth and Mini-Marshmallows." Zac, thanks so much for joining us.
UNGER: Thank you for having me. It's a pleasure.
