The polar bear is the first animal to become endangered because of global warming.
- They are the planet’s largest land-based carnivores, yet spend most of their time around water and ice.
- They are particularly at risk from global warming, which is causing the ice they depend upon in the Arctic sea to melt.
- Although generally solitary, they can also be quite social. Seals are their main food. They can smell their prey in the water under a metre of compacted snow from almost a kilometre away.
- Adults are strong swimmers and can swim for several hours to get from one ice flow to another. They are protected by the camouflage of their thick white fur that together with a layer of fat keeps them warm.
