What is the impact of cobalt mining in the congo? Will give brainliest if your answer is good! Also please include as much detail as possible thank you :)

Cobalt is an essential material that is mainly used in lithium ion batteries which are found in smartphones and some electric vehicles. Congo provide majority of the worlds supply of cobalt. Although having a surplus of valuable materials, Congo is one of the poorest nations. Because of the lack of money, those who mine cobalt in the Congo do not used power tools, gloves or mask, but instead they use their hands. With that, the miners would be exposed to high level of cobalt. Lung disease and heart failure have been linked to high levels of cobalt, and the mines that produces it are blamed for destroying landscapes, polluting water sources, contaminated crops and a loss of soil fertility.
