It’s not as if the human and environmental toll of mining is a particularly well-kept secret. But the full extent of the damage from mining for the rare earth elements and other metals that go into electronic devices, electric vehicles, solar panels, and countless additional components of modern life can be hard to wrap one’s mind around—unless the mountain of evidence is laid out end-to-end, as in Vince Beiser’s new book Power Metal: The Race for the Resources That Will Shape the Future. The book begins with an overview of what Beiser calls “critical metals,” where they come from, and the history of their discovery and extraction, before moving on to the current state of mining and processing critical metals today.
Demand for these substances has soared in the Information Age and is projected to keep climbing. (One factoid that stood out: “Just one Tesla Model S can contain as much lithium as ten thousand mobile phones.”) The environmental damage caused by the production of critical metals is continuing to mount—and could grow in unexpected ways if, for example, companies begin mining the sea floor.
Still, humans need these substances, especially for the renewable energy technologies needed to stem climate change. There is no Cinderella-shoe solution. There are always trade-offs. As Beiser writes, “When it comes to mining, the choice is never between bad and good but only bad and less bad.”
