Pretty sure most people in USA don’t need more calories.

1 in 5 kids in the United States is living with hunger. That's nearly 14 million children, which has increased from a year ago.

Milk is a highly effective method of fattening kids up who are malnourished or otherwise underfed. Whole milk is the go-to for toddlers coming off breastmilk/formula for a reason.

Dairy is literally the least sustainable and least efficient form of food production next to meat and palm oil.

Natural gas is a leading contributor to climate change. It is also the cheapest (for the moment) form of energy per kWh.

"Sustainability" is not the same thing as "Cheap" or "Easy to Distribute". Quite the opposite.

Now, a lot of our cheap milk is a byproduct of our intensive animal agriculture, which is highly profitable but dismally inefficient. If that changes (because we killed a big chunk of our cow herds by mismanaging grazing land and water rights and fucking up disease mitigation) then I can see a world in which cow-milk drops off the menu quickly.

So, hey, let me know if that changes.
