The death of gallium  JUL 07 2008

Humans are consuming natural resources so quickly that we're running out of elements.

The element gallium is in very short supply and the world may well run out of it in just a few years. Indium is threatened too, says Armin Reller, a materials chemist at Germany's University of Augsburg. He estimates that our planet's stock of indium will last no more than another decade. All the hafnium will be gone by 2017 also, and another twenty years will see the extinction of zinc. Even copper is an endangered item, since worldwide demand for it is likely to exceed available supplies by the end of the present century.

Many of the elements listed above are used in the construction of computer equipment and flat-panel TVs.
