Is it? I would expect the variance in the sustainability to be quite high, with the most sustainable (pasture fed) dairy farms being much better than the average almond milk producer. That’s just an intuition though. Also assuming we’re talking per gram of protein and fat here. Cup for cup almond milk might be more sustainable but there’s far more nutrition in a cup of cow milk.
An almond tree lasts for decades while a dairy cow has a considerably short life during which time she is abused by the Ag system and releases methane, poop, consumes a lot of inputs and a lot of water and labour and fossil fuel and electricity and refrigeration. It costs a dairy farmer more to produce a gallon of milk than it costs the consumer to buy it. It’s an industry entirely supported by subsidies. So it’s not…
The heuristic “plants are generally more sustainable” reads true to me. But “pick the better kingdom” seems like such a low bar to clear. I’d like to head towards actual understanding of embodied energy, cruelty, etc per unit of useful nutrition in specific meal plans.
