BRUNSBUETTEL, GERMANY - AUGUST 03: Cargo ships pass along the North Baltic Sea Canal (Nord-Ostsee-Kanal) August 3, 2007 at Brunsbuettel, Germany. The canal, first completed in 1895, is 99km long and connects the North Sea with the Baltic Sea, allowing ships to travel between the seas without having to go north around Denmark. Northern Germany, with its busy ports of Hamburg, Bremerhaven and Kiel, is a hub of international shipping.  (Photo by Sean Gallup/Getty Images)
