Hello, good question! The fact you’re troubled by how everything is fucked up around us is a pretty good sign that you’re a decent human being with a functioning heart! Unfortunately a system of extraction/refinement/production can very hardly be ethical.

See for example this article about whether manufacturing computers would be possible at all in an anarchist society.

The best we can do is consume less, as a society. As individual, there’s nothing we can do at all. Even if you buy nothing at all, our surroundings as westerners is more destructive to the environment that many people living fulfilled lives. Concrete, plastics and electronics are probably the WORST that can happen to the environment, and they’re all that our cities are made of.

Dismantling industrial capitalism and its cities is the only way forward, if you want to have a semblance of ethics. Buildings/production on a smaller scale can be very ethical, by following principles of permaculture for example. In the meantime, consuming less is a course of action, but liek i said individual action isn’t gonna cut it: forming workers/buyers cooperatives, though, can help a lot in developing autonomous infrastructures that can surpass and survive capitalism.
