Have you ever seen those aquarium ornaments that look like shipwrecks? Well, the U.S. Navy is applying that idea in real life.
In 2006, the Navy intentionally sank one of its old boats off the coast of Pensacola, Fla. The U.S.S. Oriskany, which had served in the Korean and Vietnam wars and launched the last bombing mission of Sen. John McCain, became an “artificial reef.” The Navy has 59 decommissioned ships sitting around and nothing to do with them—while most will become scraps, some might become reefs. But is sinking more old ships really a good idea?
