Other resource depletion
Once, black caviar from the Caspian Sea was ubiquitous in Russia in its typical blue cans. Now, it has disappeared. "Peak Caviar" has taken place around 1980 in Russia. ... "Peak Caviar" is another confirmation of how common the "Hubbert" behavior is. It doesn't matter if a resource is theoretically renewable, as sturgeons and whales are. If sturgeons or whales are killed much faster than they can reproduce, then they behave as a non renewable resource; just as crude oil.

Probably not, but it's something you'll hear alot more about in years to come because when the earth's phosphorus supplies run out, so too will food. It sounds like a doomsday scenario, but my guest today believes deposits of phosphorus could be depleted this century.
