A Greenpeace banner reading: 'IWC: Act Now!' with Berlin's Television Tower and an inflatable whale. Greenpeace activists scale Berlin's 365 m Television Tower in Alexanderplatz and suspend a large inflatable whale from the tower's point with a banner reading "IWC: Act Now!". Greenpeace is calling on delegates at the International Whaling commission (IWC) meeting in Berlin to protect the 300,000 whales, dolphins and porpoises that die every year from environmental threats like entanglement in fishing nets, noise pollution, toxic contamination and ship strikes, as well as commercial hunting.
