To provide a bit of balance.
There is an organisation called the Fair Cobalt Alliance (FCA) whose objective is to resolve the issues of artisanal mining of cobalt in the DNC.
It appears that Tesla amongst others (including the UK's own Britishvolt) is a member of the FCA.
It would have been equally appropriate for Panorama to have attacked Britvolt and all the other battery manufacturers who are using Cobalt from DNC or equally they could have provided some balance by highlighting the work being carried out by the FCA to improve the situation.
