The land used for feed is super low-value land that has no better use. It does contribute a bit to global warming though. The collective action problem we have to solve in order to stop global warming is much more difficult than just getting people to stop eating beef. If you believe feeding livestock in the most cost-effective manner available is wasteful, then there must be an implied route toward less waste. Maybe: -the government should decree beef and pork illegal -or implement some sort of high tax or cap and trade measure for livestock and meat -and perform a massive propoganda campaign to teach people that they should raise their own chickens, eat more beans, and eat less meat/protein overall. The problem of people not starving to death around the world is not an issue of food supply, it is an issue of food distribution.
