> If we want to address global climate change, then we need to look into minimizing total energy put into things like food. Often that will mean growing things where they can grow most easily, with the least amount of energy.

The big issue with agriculture and environmental disasters like climate change and biodiversity loss is land use patterns. That implies a need to drastically replace consumption of very land-inefficient uses like beef with mostly plant based foods.

But yes, I completely agree with you that 'food miles' is largely a distraction.
