Metal and mineral needs are constant, constantly evolving, requiring new mines
Civilization’s progress has always been heavily dependent on farming and mining. The Stone Age didn’t end because mankind ran out of stones.
Instead, the discovery, mining and processing of metals like copper, bronze and iron, followed by the development of steel, led to progressively sharper, more effective tools, improved construction techniques, and other engineering and technological achievements. Nonmetallic minerals have also been and remain vital to civilization and progress.
Minerals – or their scarcity – have precipitated wars, but more often have led to certain countries becoming dominant in manufacturing vital products such as computer chips.
