Hubbert peak theory - Wikipedia, the free encyclopedia: "The Hubbert peak theory, also known as 'peak oil', concerns the long-term rate of extraction and depletion in conventional petroleum and other fossil fuels. It is named after American geophysicist Marion King Hubbert, who created a model of known oil reserves, and proposed, in a paper he presented to the American Petroleum Institute in 1956 [1], that production of oil from conventional sources would peak in the continental United States between 1965 and 1970, and worldwide within 'about half a century' from publication."

future trend: plastics will become too expensive, carbon nanotubes will replace plastics. Invest in carbon nanotube / nanotech companies.
