A passerby takes a picture of a Dinosaur made out of old oil barrels in front of the Cologne Cathedral during a Greenpeace-Protest against the Shell Rhineland refinery. Greenpeace demonstrates simultaneously in the North Sea with the Greenpeace ship Esperanza in the Brent oil field. In April, a leak at the refinery contaminated the soil and groundwater with hundreds of thousands of liters of oil. In addition, the company plans to leave parts of four old oil platforms with 11,000 tons of oil to rot in the North Sea.
