Just months after the Gulf of Mexico oil spill, another oil spill hit the United States, this one in Michigan. But the clean-up for this one has been long, involved and convoluted.

An American company and an Italian company are set to begin salvage operations off the coast of Italy later this month, to recover the shipwrecked Costa Concordia. The effort is intended to remove the vessel intact, to prevent fluids from leaking out and polluting the surrounding environment.
