The word “critical” used in this sentence suggests there is no way to produce or distribute food or other commodities without fossil fuels, which is plainly, obviously false.

If it’s plainly false you’ll have no trouble explaining how, plainly. How do we feed the worlds population without fossil fuel produced fertilisers and fossil fuel distribution
