In 1996, the vital Molycorp mine was accused by the Bureau of Land Management of running afoul of regulations to protect the desert-tortoise habitat. After paying a series of fines and spending a fortune to jigger its mining so as to accommodate protectors of the desert tortoise, the company that supplied almost all the U.S. rare earths laid off hundreds of workers and stopped production."
