Greenpeace launches "Save the Arctic Campaign" in Rio de Janeiro, Brazil, during the Rio+20 Summit, using a balloon in the shape of a polar bear. The activity is part of the 'Arctic Rising' actions which follow the rising sun across the globe on the longest day, June 21st. Greenpeace is campaigning for a global sanctuary around the north pole, and a ban on oil drilling and unsustainable fishing in the wider Arctic.
