At Zoom Erlebniswelt Gelsenkirchen a polar bear baby was born on the 4th of December in 2017. It’s called Nanook. In nature only 15% of the polar bear babies survive. At modern zoos and aquariums more than three times more survive. The polar bears being part of the breeding program of modern zoos and aquariums live normally twice as long as their wild counterparts. The amazing playing behavior of mother and baby proves their welfare. Modern zoos and aquariums massively support the conservation of polar bears. The animals are important ambassadors for their threatened counterparts in the wild.
