Colorado State Geologist Vince Matthews[right, credit CGS] warns that “We’re depleting natural resources all over the world," and are increasingly at risk of shortages of energy and minerals. Vince spoke at the recent 3-D Seismic Symposium in Denver and his talk is reported in the June issue of AAPG Explorer magazine (p12).
He's quoted as saying "a total of 50 percent of all copper mined and 50 percent of all oil consumed has taken place since 1985." In addition, international companies, many nationally owned, are buying up U.S. reserves of energy and minerals which may mean that we wake up one day and discover we don't own them any more.
