Save a polar bear, buy wooden furniture
Apparently, pollutants called polybrominated diphenyls, or PBDEs, are wreaking havoc on the nervous systems of polar bears. The compound is a flame retardant found in carpets, clothes and furniture coverings. It has also been discovered in the bears' fat. Researchers assume the pollutants were carried by ocean currents to the Arctic. The worst part? Uh, the bears with high exposure levels can become hermaphrodites. In fact, 1 in 50 females in Svalbard, Norway also happens to be a dude.
