Increasing Oil Reserves

An annual British Petroleum report claims that the world has enough oil reserves to last 40 more years. The study, based on officially submitted figures, shows 15 percent more proven oil reserves globally than a decade ago. In fact, only North America has less known oil now than it had 20 years ago. Governments often rely on the BP reports, but many scientists question whether the world really has that long to go before its fuel gauge hits empty.
