Milk - White Poison or Healthy Drink?

When humans domesticated barnyard animals (goats, sheep, cows) starting around 10,000 years ago, they stumbled upon one of the most amazing schemes of all time. Instead of relying on the few human-edible plants scattered around for their energy needs, humans could raise animals that ate the plain old grass that was growing anywhere & everywhere and converted it into ultra-nutritious and energy-rich superfoods like meat and milk. Land back then was plentiful and the scheme allowed humans to produce many more calories with less effort using an energy source (the grass) that they didn’t otherwise have much use for.

But how does milk fit into the picture these days? It’s still a superfood that’s very beneficial to people in many parts of the world where adequate nutrition isn’t available from other sources. But as Kurzgesagt explains in this video, our land use has changed in the past 10,000 years, and cow’s milk production is a major source of carbon emissions (when compared to foods w/ similar nutritional value):
