A Greenpeace team including four young ambassadors, Kiera Kolsen from Canada, Renny Bijoux from the Seychelles, Josefina Skerk from Sweden and Ezra Miller from USA (Team Aurora), trek to the North Pole. They are carrying with them a time capsule containing 2.7 million names of supporters who wish to protect the Arctic. They lower the capsule and a ‘flag for the future’ to the seabed beneath the North Pole. The trek is part of an ongoing campaign calling for a sanctuary to be declared around the pristine and uninhabited area surrounding the North Pole. The region is currently under threat from climate change, oil companies, industrial fishing and shipping.
