Peak oil: Ecologists and geologists have warned about oil depletion for decades. Geophysicist M. King Hubbert described the phenomenon in 1956. He was largely ignored. Global peak oil per capita occurred in 1979 and we have now arrived at the absolute peak - just as predicted.

Net Energy: Oil depletion and society's oil addiction drives us toward lower-grade reserves, such as tar sands, with a low net energy, costing more energy to retrieve, returning less to society and emitting more pollution. Researchers such as Charles Hall at the State University of New York warned society about this in the 1970s.
