It also allowed for new tools to be made such as scythes that increased agricultural production and created surpluses which means that metallurgy was a part of the first agricultural revolution which also means that it spurred urbanization. Unfortunately‚ smelting iron required lots of wood and caused deforestation

capital have long been obvious. The savings in terms of reduced environmental impact are less obvious but increasingly important. The obstacle to greater use recycling has been the fact that economies of scale still favor large primary mining and smelting complexes over (necessarily) smaller and less centralized recyclers. But this advantage is declining over time as the inventory of potentially recyclable metals in industrialized society grows to the point that efficient collection and logistic
