Neither production nor logistics is solved at all. We have bought ourselves time, largely by racking up environmental debt on our planetary credit card. Food is still massively dependent on fossil fuel consumption (machinery, transport, fertilizer).

The good news is that the answer is to reduce the cost and carbon impact of energy production, and we’re making great progress here, but we cannot afford to take our foot off the gas, because although Ehrlich was wrong about the timing, he wasn’t wrong in his fundamental observation that the Earth has a finite carrying capacity.
