The Rare Earth Crisis—The Supply/Demand Situation for 2010–2015

The rare earth elements impact nearly everyone in the world. All of the people living in advanced technological countries and almost all those living in third world countries utilize the rare earths in their everyday living—the car that one drives (gasoline is refined from oil using rare earth catalysts and catalytic converters reduce the polluting emissions from the automotive exhaust), watching the news on TV (the red and green colors in TV screens), the telephones and computers we use to communicate (the permanent magnets in speakers and disc drives), just to name a few examples.
