Containers are all around us, on ships, trains and trucks. The biggest container ships can carry 19,000 containers and, at any one time, there are more than 2000 such ships at sea. 90% of everything that is purchased in North America has at some stage been in a container. Container shipping replaced more labour intensive methods in the 1970s. Then, dock workers fought back, hoping to preserve their jobs but inexpensive container shipping won out and is part of the reason goods made in Asia are so cheap and plentiful. Today, we hardly notice these sturdy and robust warriors of ship, rail and road.
