Non Renewable Natural resources how much is left?

All of the following figures come from the prestigious French magazine, Internationally renowned and highly regarded by the Scientific community: Science et Vie, June 2008.
All the figures are based on proved and probable reserves and assume current consumption stays the same. Of course, both assumptions are unrealistic as more reserves may be found but since world population is expected to rise by another 30% over the next 40 years, new discoveries may be offset by a rising population's needs.

Conclusion: 100 years from now, the Planet will have been pillage, future generations will have nothing left to build on and our legacy to them will be a climate in which they can barely live in. That's why they politely call our mode of development unsustainable. In reality, anyone who agrees with it is either barking mad or totally ignorant. Unfortunately, the majority in this instance may be excused for total ignorance. Thank the corporations, the press and your government for that. If any of these representatives are still alive when the shit hits the fan, maybe we can get the guillotine out again for consolation and chop their heads off. Future generations are going to need a triple doze of Prozac to cope with the reality we've left for them to inherit. Smile, you're part of the developped, civilized world.
