Deep sea mining for rare earth elements and other critical minerals could start as early as 2026, even as 38 countries have called for a moratorium on it. The metals that companies are targeting are used in many green technologies like electric cars and wind turbines – but mining them is destructive to the environment. Some in the mining industry say the mining is necessary to a green transition – and essential to democratizing that transition globally since the supply chain is currently dominated by a single country, China. Meanwhile, some scientists caution against mining before the full scope of environmental damage can be understood. Can there be balance in this environmental and political push-and-pull? Hosts Regina G. Barber and Emily Kwong dive into this debate and talk about what science has to say. Curious about other science controversies?
