Greenpeace activists dressed as polar bear scale Brussels' Town Hall to demand immediate global action to protect the Arctic. The activity is part of the 'Arctic Rising' where polar bears descend on famous buildings and landmarks across the world. The global actions follow the rising sun across the globe on the longest day, June 21st. On this day the sun never sets on the Arctic. Greenpeace is campaigning for a global sanctuary around the north pole, and a ban on oil drilling and unsustainable fishing in the wider Arctic.
