polar bear changing diet




the disappearing of sea ice made it harder for polar bears to catch seals, so now they are poaching eggs from gooses nests! these eggs couldn’t provide the right nutrition for the polar bears, but in order to survive they don’t have much choice. the changing of polar bear diet not only affect the bird populations, but animals like the arctic foxes and reindeers that depends on the birds would be affected as well, and changing the whole terrestrial ecosystem.
