Regenerative beef rearing and crop farming is FAR better for the environment than large commercial monocropping of grains and corn. It's not even close to a comparison.
It's a red herring they like to use to demonize red meat. I would be all for removing large scale commercial production, but the huge conglomerates that lobby DC and big pharma that wants to keep treating a disease ridden populace that is primarily the fault of highly processed foods doesn't want that.
