For harp seal pups, survival depends on its first ten days

We head away from land onto the ice floes of the Gulf of St. Lawrence, where thousands of harp seals are giving birth to tiny yellow pups. The adults have come so far south from their feeding grounds that this forms a unique oasis away from their main predator, the polar bear. But there’s a catch. From the minute the pups are born, they enter a race against time. In one of the shortest mammal weaning periods, the pups have just 10 days to drink all the milk possible and start swimming before their mothers abandon them on melting ice. Our changing climate means the stakes couldn’t be higher. If the ice melts before they learn to swim, this generation of pups will drown. The visuals in this episode are magical, with unbelievably cute pups peppered across the ice. This story is a unique opportunity to get up close and personal with ice, both above and below the surface. This episode will ultimately bring to life the message of the entire series: We are all inextricably tied to sea ice.
