Human disturbance increasing cannibalism among polar bears

Russian scientists record more cases of bear-on-bear attacks amid food scarcity and sea ice melt

Cases of polar bears killing and eating each other are on the rise in the Arctic as melting ice and human activity erode their habitat, according to a Russian expert.

"Cases of cannibalism among polar bears are a long-established fact, but we're worried that such cases used to be found rarely while now they are recorded quite often," said Ilya Mordvintsev, a polar bear expert, quoted by Interfax news agency.
