Umm, its not to hard to do in the US. We have a farmer friend who has more ground beef than he knows what to do with. Hell, even Coscto sells Florida sourced organic ground beef.I was more responding to fly to be honest. Nobody here eats pasture raised beef. And even if they do the whole planet is going on fire because of it. Taste buds don't matter.
There's also a ton of sustainable ways to raise beef. I'm guessing you're probably too closed-minded to listen to Joel Saladin on Joe Rogan, but if not, he's had some really interesting and educational podcasts about the topic.
Either way, the taste of it is a valid question - because I haven't found any that I like.
