Polar bears are the largest member of the bear family. They live in the planet’s coldest climates, protected by their thick coat of fur and layer of fat. They sit at the top of the Arctic food chain and feed primarily on the fat of seals, whose remains provide food for many other wildlife species.
However, warmer temperatures, melting polar ice caps, and arctic drilling are causing polar bear population to shrink in areas where they once thrived. As their icy habitat melts, it is increasingly difficult for polar bears to travel, hunt, and raise their young. Not to mention, oil spills pose a very high risk to polar bears and their habitat. Without protection, polar bears could disappear entirely by the end of the century.
