On: Farmed salmon leads to loss of nutrients, instead eat 'feed fishes' directly

[FredPret]

Cows do an outstanding job turning grass and other inedible things into a foodstuff that not only has extreme nutritional value, but resonates with me on a cellular level.

It'd be cool if we can grow steak in future, but I think it'd be very hard to replicate an actual cow without adding toxins, and I worry that they'll make some ridiculous low-fat or low-cholesterol version based on nutritional "science".

Cows are extremely inefficient. How can you say they do an outstanding job? Outstandingly high emission of Methane belching?

Efficiency isn't the only way to do an outstanding job.

When Michelangelo painted the Sistine Chapel, it took him forever to paint a small surface. Any old housepainter could have been more efficient.

The point is that grass is inedible and grows all over the place, and cows turn this abundant and useless resource into wonderful steaks.

Cows are literally one of the least calorie-per-CO2 efficient means of getting meat. Here's some actual data: https://ourworldindata.org/grapher/ghg-kcal-poore

You'll note that beef is by far the worst.

Here's one that better describes the components of that CO2 footprint (whether it's methane production, or transport overhead, etc.): https://ourworldindata.org/food-choice-vs-eating-local

I refer you to my reply to your sibling comment.

Michelangelo did a less efficient job painting the Sistine Chapel per square meter than a housepainter would have.
