    In an effort to control chemicals emitted from motor vehicles, great quantities of relatively rare metals are used for catalytic converters. Are we running out of such metals? If so, where can more be acquired? What are the consequences of doing so?

    You observe that there are sources of metal unexploited closer at hand? Very true, though article cited does not refer to platinum and rhodium per se. Mount Erebus in Antarctica produces gold, though exploitation of same does not appear to be probable in short term. Thank you for participating.

    Related article same source reveals objections from biologists, environmentalists, surprise, surprise. These people will perhaps not be as ready to object to asteroid mining, no ecosystems or indigenous peoples to be threatened.
