The Democratic Republic of Congo is one of the poorest countries on Earth. But it holds the world’s richest deposits of cobalt. Now the race is on to mine the metal essential to making electric car batteries. People in this region are digging and dying for. It is dangerous work. The massive industrial mines are a law until themselves. People are dying for lack of safety. Corruption and violence and rampant. Small scale miners who work on the fringes of the mine risk arrest and even death. Many are children. This is the cost of our green energy revolution.
