Big Picture Science - Testing Your Metal
Catalytic converters are disappearing. If
you’ve had yours stolen, you know that rare earth metals are valuable. But
these metals are in great demand for things other than converters, such as
batteries for electric cars, wind farms and solar panels.
We need rare earth metals to combat climate
change, but where to get them? Could we find substitutes?
One activity that could be in our future: Deep
sea mining. But it’s controversial. Can one company’s plan to mitigate
environmental harm help?
