Perhaps not. Maxerickson pointed out production could be shifted away from meat to legumes in the event of serious shortages. Seems right in line with climate goals.
Good luck growing legumes on the acreage currently used for beef production… you can hardly walk much less tractor incredible expanses of this land. Beef cattle very efficiently convert the grasses on these lands into healthy, nutritious food for humans.
It’s terrifying to realize how many of the people trying to influence food production have little if any practical knowledge of how farming actually works. People are going to starve to death en mass if your ilk have your way.
That is, admittedly, a lot higher than I was expecting! But 70% is still a sizeable majority. Moving the entire industry to grassland feeding would likely result in a fundamental upwards shift in how beef is priced, one that I suspect the GP would be unwilling to accept.
