Summary
Alain Prinzhofer is a geochemist at the Institut de Physique du Globe de Paris (Paris geophysical institute - IPGP) and he explains why the price of raw materials is rising more than that of the oil barrel.
Why, for example, has copper or helium become so expensive? Have we already exhausted all the resources of our planet? Can we still hope to discover new mines and new deposits?
