The Critical Supply of Minerals and Elements for Technology

The guys over at the Oil Drum are obsessed with counting things: how much of anything is left in the ground, etc. The graph posted here is an estimate of how much minerals and elements are left to be mined that are critical to our current technology and how long that supply will last, given current uses. I'm not sure of the date of this information, and I cannot vouch for how accurate it is. But it's certainly a spectacular graph and is at least informative on the types of minerals we use and suggestive of the supplies we need. The graph was posted in a response to a
post about an article in the November Scientific American, "A Plan for a Sustainable Future."
