The adoption of electric cars has been hailed as an important step in curbing the use of fossil fuels and fighting climate change. There is a snag, however: such vehicles require around six times as many metals as their gasoline-powered counterparts.

Guest: Eric Lipton, an investigative reporter for The New York Times.

• Here are some of the seabed authority emails and other documents The Times assembled as it worked on its investigation of seabed mining.
