Polar bears are black with clear fur, so in daylight, they appear white; at night, they are invisible. Young Polar bears stay with their mothers for 1-2 years, and they become mature when they are 5-6 years old.
A boar (adult male) weighs around 350-700 kg (770-1,540 lb), while a sow (adult female) is about half that size. Polar bears help us gain an understanding of what is happening throughout the Arctic. All recent indicators show that sea ice in the Arctic is melting at an alarming rate, a problem that needs to be addressed immediately if polar bears, and other species unique to the region, are to survive. On International Polar Bear Day, we're grateful to Payworks for announcing a $35,000 donation to Polar Bears International as part of their 20th anniversary.
