That won't solve any environmental problems, as in most cases there are no plausible recyclable substitutes. Or are you proposing we make iPhones out of wood?

That won't solve any environmental problems, as in most cases there are no plausible recyclable substitutes. Or are you proposing we make iPhones out of wood? All that'd do is act as a general consumption tax, and we already have those. In fact there are no viable solutions, assuming rolling civilisation back to the stone age isn't considered viable. That's why eco-extremists never get specific about what they want corporations or governments to do, and in the rare case where someone is actually serious enough to consider that problem they end up leaving the environment movement: see the long history of ex-Greenpeace or now ex-Extinction Rebellion leaders leaving the movements and coming out in favour of nuclear power.
