In that case, we have destroyed about 50% of the earth's natural biomass and we are near the point of depletion of the earth fish stock. That means that an order-of-magnitude increase in consumption, which would trivially happen is all of the earth's existing population were to have first-world consumption standards, would completely wipe away a sustainable society. As far as I know, order-of-magnitude reductions in consumption of basic resources while keeping living standards is not something we are anywhere remotely close to achieving.
