Winning raw materials Utilizing raw materials Using natural resources Encouraging exploitation of natural resources Facilitating extraction of natural resources Exploiting available natural resources
Claim:
With regard to subsoil resources, the world becomes ever more adept at discovering new reserves and exploiting old ones. Exploring for oil, for example, used to be a hit-or-miss proposition, resulting in a lot of dry holes. Today oil companies can use seismic waves to help them create precise computer images of the earth. New methods of extraction -- for example, using bacteria to leach metals from low-grade ores -- greatly increase resource recovery. Reserves of resources are actually functions of technology. The more advanced the technology, the more reserves become known and recoverable.
