Global Warming Turning Polar Bears Into Cannibals
It is an image that is sure to shock many people.
An adult polar bear is seen dragging the body of a cub that it has just killed across the Arctic sea ice.
Polar bears normally hunt seals but if these are not available, the big predators will seek out other sources of food - even their own kind.
... environmental photojournalist Jenny Ross...told BBC News.
".... there are increasing numbers of observations of it occurring, particularly on land where polar bears are trapped ashore, completely food-deprived for extended periods of time due to the loss of sea ice as a result of climate change."
Nothing to do with there being too many bears....
