Let's say a hypothetical anarcho-syndicalist federation employs technologies requiring precious metals (e.g. silver) or conductive metals (e.g. copper) or fossil fuels (e.g. petroleum) or rare earth elements such as Cerium, Europium, Yttrium, Neodymium, Praseodymium, Dysprosium, Terbium, and Lanthanum for a hybrid electric car's UV cut glass, glass and mirrors polishing powders, LCD screen, component sensors, hybrid electric motor and generator, headlight glass, 25+ electric motors throughout vehicle, catalytic converter, hybrid NiMH battery, diesel fuel additive, etc.
Now, where do they get these materials from? How do they access the landbases in which to mine them (and who mines them)? Where does the pollution go, who bears the burden of leftover cyanide waste for gold mining and leftover sulfuric acid waste for copper mining? Do they simply inherit processes of colonial exploitation at the expense of indigenous populations dispossessed by the capitalist state? What if humans refuse to allow the mining to take place, either from prior inhabitation, or in solidarity with the integrity and biodiversity of the landbase and its species?
