Peak caviar

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.

Coal & Climate

Recent reports on global coal reserves, surveyed in previous chapters, generally point to the likelihood of supply limits appearing relatively soon—within the next two decades (a contrary view is represented solely by the BGR report [“Lignite and Hard Coal: Energy Suppliers for World Needs until the Year 2100 – An Outlook,” 2007]).
These two trends are surely destined to interact, and the uncertain result will shape climate and energy policy in the years to come.
