Earlier this week, six U.S. tech companies were named in a lawsuit that accuses them of endangering the lives of child laborers in the mining of cobalt for their products. Several children have been maimed or killed in pursuit of this rare element, most of which comes from the Democratic Republic of Congo. The lawsuit, the first of its kind, names Apple, Alphabet, Microsoft, Dell and Tesla. “This is the first time that tech companies have been on the hook for this,” Roger Cheng of CNET tells host Molly Wood.
