Earlier quoted context omitted.
For grass fed cattle, the vast majority of said water is from rain that would have fallen on the land with or without the cattle. It's not generally municipal supplies of water in use for naturally raised cattle.
Absolutely. But not all beef is grass fed. The situation would be very different if it was.
As to alternatives for real meat not grown as animals... we don't even get micro-nutrients for baby formula right... I won't trust alternatively grown meat for a very long time. I and my brother wouldn't have survived on conventional baby formula... I have issues with just about everything outside eggs and red meat.
As for all beef being grass fed/finished... I'd be way more than happy to see it become the norm, exceptions for snowy parts of the year only. I'd like to see regenerative farming, which pretty much requires ruminant cycles, be the norm everywhere... we need more ruminants, not less imo.
