As the world heats up and polar ice melts, different types of bears, whales and seals could meet and mate — but these unions may be far from happy, researchers said Wednesday. In fact, interspecies sex brought on by the melting Arctic ice could lead to the extinction of many endangered Arctic animals, the scientists said in an article published in the journal Nature.
