Yes, our industrial consumer culture is doomed. It has been doomed, ever since the coalesce of fossil fuel discoveries and exploitation and the zero-sum money economy (mislabeled “capitalism” although it is not actually an “-ism” at all, but a rule-based game, like Monopoly, with only two rules: More is better and What’s mine is not Yours).
This coalescence of oil and money games depends entirely, for its viability, on endless growth of extraction of resources, production and consumption of commodities, coupled with the upward concentration of wealth, and the consequent degradation of our biological support systems.
Yet it completely ignores the obvious fact that our planet—our biological support system—is finite, and that we are every bit as dependent on its ecological functions as every other organism. When that global ecosystem collapses, so will we.
