2. Given that 97 percent of rare earth metal production is now done in China, an increase from 27 percent to 97 percent between 1990 and 2010, do you think countries such as Australia, Canada, and the United States should reconsider their environmental restrictions on product of such metals?

Rare earth metals are a set of 17 chemical elements in the periodic table and include scandium, yttrium, cerium, and lanthanum. Small concentrations of these metals are a crucial ingredient in the manufacture of a wide range of high-technology products, including wind turbines, iPhones, industrial magnets, and the batteries used in hybrid cars. Extracting rare earth metals can be a dirty process due to the toxic acids that are used during the refining process. As a consequence, strict environmental regulations have made it extremely expensive to extract and refine rare earth metals in many countries.
