Material Matters: The Past and Present of the Rare Earth Elements Essential to Our Future

Public Events
Wednesday, December 8, 2021
4:00 p.m.–5:00 p.m. PST (UTC -8)

Institute research curator Roger Turner discusses how science and history can teach us to produce needed rare earth metals while minimizing harm to humans and the environment.

Today’s electronics and the green energy technologies we’ll need for the future depend upon rare earth metals. But producing these metals in the past often involved exploitation and harm. The surprisingly global story of rare earths shows how science and history can help us imagine better ways forward.
