Oceans could yield new sources of rare earth elements

Rare earth elements aren't actually rare, but right now the vast majority of them (97%) come from a single place — China. Given how important these elements are to the making of everything from computers to cars, that gives China quite the monopoly. With that context, here's the news: Japan just found a big supply of rare earth elements in mud at the bottom of the Pacific Ocean. Of course, what may be good news for manufacturing is not necessarily good news for the health of oceans.
