I had heard that electric cars might be worse for the world than gas, and the batteries are the problem, but didn‘t know why. One huge reason is that they require cobalt- all rechargeable batteries do. Cobalt comes from the Congo, where people of all ages (yes, children too) work in the worst conditions you can imagine, risking their lives, for on average a dollar a day. And they have no choice, it‘s the only work available.
