"But here's the catch. Rare earths always occur alongside the radioactive elements thorium and uranium, and safely separating them is a complex process. Miners use heavy machinery to reach the raw ore, which contains anywhere between 3 and 9 percent rare earths, depending on the deposit. Then the ore is taken to a refinery and "cracked," a process wherein workers use sulfuric acid to make a liquid stew of sorts. The process is also hugely water- and energy-intensive, requiring a continuous 49 megawatts (enough to power 50,000 homes) and two Olympic swimming pools' worth of water every day.
Workers then boil off the liquid and separate out the rare earths from rock and radioactive elements. This is where things get dangerous: Companies must take precautions so that workers aren't exposed to radiation. If the tailings ponds where the radioactive elements are permanently stored are improperly lined, they can leach into the groundwater. If they are not covered properly, the slurry could dry and escape as dust. And this radioactive waste must be stored for an incomprehensibly long timethe half-life of thorium is about 14 billion years, and uranium's is up to 4.5 billion years. Reminder: Earth itself is 4.5 billion years old.
Not coincidentally, the refining tends to happen in areas where weak environmental rules mean that companies can process the elements on the cheap. Take the Baotou region of Inner Mongolia, where most of China's rare-earth mines are clustered, and where waste has leached into waterways and irrigation canals, according to several independent investigations. Communities around one former mine in Mongolia blame at least 66 cancer deaths on leaked radioactive waste, and local people complain that their hair and teeth have fallen out."

Our obsession with having the latest and greatest tech gizmo is having a direct impact in countries on the other side of the world. Is this going to be another one of those times when Americans simply shrug and go back to buying a new phone every eighteen months, or will we actually do something constructive, demanding, at the least, that companies operate in a clean and responsible manner. Better yet, will the American public finally stop being fascinated by the latest, greatest shiny new toys and reduce their demand for the labor that is killing people in Asia and elsewhere.
