Should factory farming be phased out within ten years?

Livestock supply chains account for roughly 14.5 percent of human-caused greenhouse gas emissions, according to the UN Food and Agriculture Organization, a share larger than all the world's cars, planes, and ships combined. FAO. A ten-year phaseout is not about ending meat; it is about ending the most concentrated, industrialized way of producing it. We phased out leaded gasoline and ozone-depleting chemicals on similar timelines once the science was clear, and industry adapted faster than the doomsayers predicted. The technology exists: precision fermentation, improved feed additives that cut methane, and higher-welfare systems that already operate at scale in parts of Europe. What is missing is a deadline that forces the transition instead of letting the industry lobby for one more decade of delay.
