Polar bears congregate in and around Churchill in late autumn every year as they wait for the sea ice to form in Hudson Bay so they can head out to hunt. They lead
generally solitary, nomadic lives, following the advancing and retreating sea ice, often ranging over hundreds and sometimes thousands of kilometres. Polar bears'
main food are seals - which is the only prey with high enough fat content and calories to keep a polar bear healthy - so they have adapted for a life on the ice.
Which is why climate change is such a threat to their survival, as retreating sea ice means the disappearance of their habitat. The Polar bear is officially classified
as 'vulnerable' and with continued loss of sea ice, these magnificent bears are at risk of dramatic declines in number by the middle of this century. For more information
or to support conservation efforts, please visit Polar Bears International or the
World Wildlife Fund.
