I spoke with many families whose children, husbands, spouses, had suffered horrific injuries. Oftentimes, digging in these larger open-air pits, there are pit wall collapses. Imagine a mountain of gravel and stone just avalanching down on people, crushing legs and arms, spines. I met people whose legs had been amputated, who had metal bars in where their legs used to be. And then the worst of all is what happens in tunnel digging. There are probably 10,000 to 15,000 tunnels that are dug by hand by artisanal miners. None of them have supports, ventilation shafts, rock bolts, anything like that. And these tunnels collapse all the time, burying alive everyone who is down there, including children. It's a demise that is almost impossibly horrific to imagine. And yet I met mothers pounding their chests in grief, talking about their children who had been buried alive in a tunnel collapse. And these stories never get out of the Congo. People just don't know what's happening down there.
