+1 you are correct, the subsidies given to the beef industry are absurd given the externalities of cow farts, water usage, etc.
I don’t think that beyond burgers are very healthy but my wife and I eat them at least once a week anyways. I like a maxed-out burger with the ‘works’ without having animals die for my eating pleasure. When I do occasionally eat real meat, I prefer no feed lot beef over pork or chicken because I understand that chickens and pigs live miserable lives while cattle get to live outside and graze.
