The majority of CO2 from moving food is created by you driving to the supermarket for groceries. It’s not hard to see how when you compare a 15 ton truck moving 30 tons of food, compared to a 2 ton car moving 4 kg of food. That truck can move 1000 times further than a personal car for about the same amount of CO2 per kilo of food.
This same logic means it’s more efficient to buy tomatoes from a continent away than to drive to the market to buy tomato seeds.
