If you're a TPMPrime subscriber, don't miss our latest Prime Longform on the global battle for 'rare earths', the critical metals that run your iPhone, your Android, your hybrid car and most things we associate with the high tech and post-fossil fuel world. They're pricey, incredibly messy to get out of the ground, and almost all the global supply is mined in China. It's a fascinating story that brings together tech, environmental threat and a new 21st 'Great Game' among the global powers to secure reliable supplies of the metals. It's a great read. I hope you enjoy it.
