If someone is looking to switch for sustainablity reasons, they shouldn’t be buying liquid non dairy almond either. You must need a handful of almonds to make your own almond milk. It’s wasteful in so many ways..from processing to transporting to the water content and all the middle men charges in the supply chain. Soak almonds. Peel. Purée with water..strain. Or don’t. Fresh almond milk. I realize many people won’t…
Almond milk is still way more sustainable than cow milk. Maybe not as much as homemade but still an improvement.
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.
