Meat is unsustainable
Factory farming is basically a machine that creates Superfund sites, cruelty, disease and substandard foodstuffs. While organic farms solve a lot of these problems, they require a lot of resources--especially land.
The only way to combat the problems of factory farming is to eat less meat. Like, a lot less.

There have been various responses to these horrors, including some recent attempts to improve the industrial system, like the announcement this week that farmers will have to seek prescriptions for sick animals instead of regularly feeding antibiotics to all stock. My personal reaction has been to avoid animal products completely. But most people upset by factory farming have turned instead to meat, dairy and eggs from nonindustrial sources. Indeed, the last decade has seen an exciting surge in grass-fed, free-range, cage-free and pastured options. These alternatives typically come from small organic farms, which practice more humane methods of production. They appeal to consumers not only because they reject the industrial model, but because they appear to be more in tune with natural processes.
For all the strengths of these alternatives, however, they’re ultimately a poor substitute for industrial production. Although these smaller systems appear to be environmentally sustainable, considerable evidence suggests otherwise.
