Half of the workforce of the artisanal mining sector is comprised of children. Without viable economic alternatives, most children must join their parents in rudimentary mining pits. Children as young as two years transport, wash, and crush minerals to earn half a dollar a day.

A class-action lawsuit has been filed by the human rights group – International Rights Advocates (IRAdvocates) – against Apple (NASDAQ:AAPL), Dell (NYSE:DELL), Google (NASDAQ:GOOGL), Microsoft (NASDAQ:MSFT) and Tesla (NASDAQ:TSLA) on behalf of the families of children killed or injured while mining cobalt in the Democratic Republic of Congo (DRC), as per the reporting by Financial Times.
