50 Greenpeace activists demonstrate for the protection of the oceans at the G20 Conference on Plastic Rubbish in Bremen. Representatives of the 20 most significant Industry and threshold countries meet to discuss ways to reduce the amounts of plastic rubbish in the oceans. 50 activists in bright red survival suits form the letters ‘ACT’ together with a swimming banner saying “for plastic free oceans” in a lake near the conference venue.
