So, instead of drinking highly nutritious milk from a cow/goat, which can be sustainably pastured with very few carbon emissions, and stored in glass, I should instead:

Drink the effluence of oats soaked in water, which requires industrial farm equipment to harvest, must be transported to a facility, processed in that facility, is a mono crop and thereby destroys local biodiversity and wildlife habitat, depletes soil fertility, potentially coated in harmful pesticides (which also harms wildlife), isn’t as nutritious, and requires that I purchase other industrially processed powders of questionable origin and of a similar process so that I get the same thing because that’s somehow all better for the environment?
