In the zoo or in the wild, it's a tough lifefor the polar bear

PITTSBURGH, Pa. — Koda, a 10-year-old male polar bear, shares an exhibit with 14-year-
old Kobe at the Pittsburgh Zoo. He comes out of a cubbyhole and steps out to a nearby
ledge, swinging his head from side to side. Then he backs into the cubbyhole, still
weaving his head. A moment later, he returns. He keeps doing the same thing, over and
over.
Koda isn't alone. Most polar bears in North American zoos do repetitive things. Experts call
them "stereotypic behaviors" and say they don't seem to have any purpose.
Many see these behaviors as signs of frustration. They say such patterns come from
keeping the polar bears in zoo exhibits.
But even in nature, it’s getting hard for the bears to act naturally. In the Arctic, polar bears
typically roam hundreds or even thousands of miles. But their home is starting to melt away
as the Earth warms up. Climate change is leaving the bears with less room to wander.

The Good And The Bad
Donald Moore is a top scientist for the Association of Zoos and Aquariums. He thinks zoos
can help the polar bears. He says zoo animals represent their relatives in the wild, making
people care about them. They can draw attention to the polar bears' melting home.
But many animal rights groups disagree. They say polar bears in zoos are suffering.
“Animals can be upset just by people looking at them,” said Rob Laidlaw of Zoocheck
Canada.
Laidlaw says zoos just can't give polar bears enough space. Polar bears travel up to 60
miles in a day. Even the biggest zoo exhibits are only an acre.
Others share Laidlaw's concerns. In 2003, scientists at Oxford University spoke out about
exhibits that house animals that roam long distances. They said zoos needed to make
significant changes. If not, they should stop keeping animals like polar bears.
At The Water's Edge
At the time, Pittsburgh’s zoo didn’t have polar bears. Zoo officials said the zoo wouldn't
add polar bears unless they had an exhibit that met their needs.
Three years later, the zoo opened an exhibit called Water's Edge. The exhibit was
designed with some of Laidlaw's concerns in mind. For example, the polar bears' space
includes a separate back area. That way, the bears can move in and out of public view as
they please.
Pittsburgh’s polar bears are also given special challenges. Sometimes they crush plastic
barrels. Sometimes they have to find ways to get icy fish out of other containers.
Joseph Gaspard works at the Pittsburgh Zoo. He has seen repetitive behaviors from both
Koda and Kobe. “But it’s hard to get at the heart of what it means,” Gaspard said. Maybe
it's "just kind of a release of energy" like when humans pace, he added.
Things could be worse for the polar bears. And in the wild, they probably will be.
Things Are Getting Ugly
Steven C. Amstrup is the chief scientist for a group called Polar Bears International. He
predicts that, by 2100, polar bears will no longer be found in the wild. Some scientists
agree. Others think that a few polar bears will still be able to live in far-off areas.
Right now, there are about 20,000 polar bears living in the Arctic. That sounds like a lot
compared to the 4,000 tigers living in the wild. But the problems the polar bears face might
be more difficult to stop.
When people hunt animals too much or cut down too many trees, they can be stopped.
Usually, a wildlife preserve is made. But melting ice is a different kind of problem. “You
can’t build a fence to protect (bears) from climate change,” said Amstrup.
That is why some conservationists like seeing polar bears in zoos. They want to keep polar
bears where people can see them. They say it helps people feel connected to polar bears
and want to help them.
Yet no matter how much zoos help, some feel it's just not fair to keep polar bears cooped
up in small exhibits.
