>Milk isn't THAT bad and it's so popular I think I'd leave it alone and focus on other improvements. Sometimes you just have to judge the popularity of something and find an alternative approach.

Milk only looks terrible because it's compared to beverages with little nutritional value. I don't think it's intentional. People just compare "milk" with "milk" and many people are trained to think "calories=bad" so if they do glance at the nutrition profile it's easy to think "ah—milk=less healthy!"

Of course animal milk takes more energy to produce. There's more energy in it!

When you actually want the nutrition milk offers instead of hydration, it suddenly becomes a whole lot greener. We didn't start drinking milk to mellow out our coffee or quench our thirst, we started drinking it because it's nutritious food.

(Let us also not forget that milk is a local product and transportation of heavy things like unitised liquids over long distances have huge carbon costs.)
