The world must learn to be careful with scarce supplies. The operation is known, but the interests are unevenly distributed. What practical solutions look like and why humanity is not powerless.

“Raw materials of the future” series
How exactly the big holes started is hard to say. With bare hands? With shaped stones? Anyway, at one point there was the hoe and the spade. The hoe and spade allowed for deeper holes. Anyone who digs deeper holes will encounter new materials. Anyone who finds new material can make new things with it. This is how coal came into being and the steam engine came into being in the world. The hoe and spade became jackhammers and excavators, derricks and bucket wheels, conveyor belts and dump trucks. Advanced technique, deep holes.
