How have the harp seals been affected by global climate change and a decrease in sea ice?

    The lack of sea ice has had disastrous effects on harp seal breeding.  Sea ice is necessary for mothers to nurse and feed pups directly after they’re born.  Without the ice the pup drown immediately following birth.  In 2007, Canadian wildlife authorities estimate that the complete absence of sea ice led to 100% harp seal mortality rate for that birthing season in the Gulf of St. Lawrence.
