> Large farms move their crops in larger, more efficient vehicles. The efficiency offsets, to some degree, the distance. Yes I understand this. My point was that it's not as simple as comparing trains to old pickup trucks, which seemed like a strawman. But I've been doing some research and was surprised to learn that food-miles are a relatively small portion of the emissions associated with food, so point taken. > You also are conflating organic and polyculture farming. Most organic farming is monoculture and much of it is industrial. I didn't mean to conflate them, I meant that monoculture + industrial is more resource-intensive than organic + small-scale. But I guess I was using "organic" as a catch-all for sustainable farming practices, e.g. polyculture, rather than literally "USDA organic". Debate about "local produce" aside (which I probably should have let go), my more important point is that it's definitely possible to reduce your carbon footprint meaningfully.
