Leonardo DiCaprio made millions for portraying smuggler Danny Archer in the film "Blood Diamond," which supported mostly unworkable and now defunct efforts to certify that diamonds did not come from "conflict" areas. He loves modern gadgets and takes great pride in being able to lecture "commoners" about safeguarding Earth's climate--while flying to Earth Day events on private jets, getting chauffeured in limousines, and being driven to Oscar ceremonies in a heavily subsidized Prius.
It turns out, hybrid and electric vehicles are not so "green" and "eco-friendly," after all. Ditto for cell phones, laptops, wind turbines, solar panels and a plethora of technologies that utilize batteries, magnets and other components which require cobalt, lithium, rare earths and other metals.
Many of those technologies trace their ancestry to mines, mining and processing methods, and countries that don't come close to meeting modern standards for environmental protection, child labor or "corporate social responsibility." You could call them "blood technologies" and "conflict metals."
