rare earth metals

China produces 90% of rare earth metals and is now in a row. People claim that are holding out on us. Not giving us access. Well, the problem with rare earths is that they are rare. There was in California a rare earth mine. It was closed down by environmentalists who were crying. They want to shut down all technology and go back to the primitive, a wish they will get soon. High tech depends on silicon which is very common. However, it also depends on metals like europium that china is limiting due to a shortage that is on going.
