Activist Ida Marie gives a tour of "Camp Dan" on the oil rig Dan Bravo.
Four activists from Greenpeace Denmark have swum from the Greenpeace ship Rainbow Warrior across the Dan oil field in the Danish North Sea and are peacefully occupying the Dan Bravo oil rig to demand an immediate ban on all further oil and gas exploration in Denmark, followed by a complete phase out of domestic fossil fuel production and a massive expansion of clean offshore wind power.
