Per kilo, that gap is a 43 km drive in a diesel car.
Chicken: Cows and sheep burp methane and need a lot of land and feed, which is why red meat towers over everything else here.
Oats: Modest. Fertiliser, the field itself, and a bit of milling.
Per-kilo numbers skip portion size and how the food was farmed, so take them as the shape of things, not the last word.
