Leah has been to visit the only two polar bears that live in England and speak to a campaign group who don't think they should be kept in captivity.
In the UK the only way you can see a polar bear is in the zoo.
Some people think that keeping polar bears in captivity can help the species survive in the future.
We want to know what you think about zoos. Maybe you think it's a good thing animals can live in zoos or perhaps you think they should live in the wild.
