Here's why:
* Habitat: Polar bears are adapted to live in arctic environments with sea ice, snow, and freezing temperatures.
* Diet: They rely on seals for food, which they hunt on the ice.
* Deserts: Deserts are characterized by extreme heat, lack of water, and little to no vegetation. These conditions are completely unsuitable for polar bears.
Polar bears are highly specialized animals that are perfectly adapted to their harsh environment. They wouldn't be able to survive in a desert.
