> If someone can find a way to make a product near-indistinguishable from meat without raising and killing animals, it would be a massive victory for the environment (meat production is CO2-intensive), for the cause of bringing decent food to poor people, and for reducing animal suffering.
I'm all for reducing animal suffering (especially from CAFOs) but replacing meat with plants isn't necessarily a victory for the environment.
Widespread factory farming agriculture has destroyed entire ecosystems. Ever flown over the midwest? You see miles and miles of plots of the same crops repeated over and over... monocultures with very little of the original grassland remaining. Agriculture has accomplished the wholesale destruction of entire ecosystems.
"70% of all water from rivers and underground reserves is being spread onto ... irrigated land that grows one-third of the world’s food", according to _When the Rivers Run Dry: Water--The Defining Crisis of the Twenty-first Century_ by Fred Pearce. In some regions up to 90% of the water from the environment is used for irrigation.
The green revolution as we know it is only possible due to fossil fuels, the Haber-Bosch process breaking down oil to create nitrogen fertilizer. With industrial farming, all in all an acre of corn requires about fifty gallons of oil according to _The Omnivores Dilemma_ by Michael Pollan. How much fossil fuel does a typical acre of wheat or soy consume? How sustainable is it compared to pastured meat, which thrives on the renewable resource of grassland?
Bringing decent food to poor people is also a noble goal, but is fraught with a moral hazard. Many developed nations have agricultural subsidies, including the US at $1.173 billion for wheat and $610 million for soybeans as of the 2004 USDA report. The billions of dollars in subsidies causes an oversupply, and the developed nations are all too willing to dump onto other countries, putting local farmers out of business and advancing an imperialist dependency. Lierre Keith, vegan for 20 years (now ex-vegan), in her book _The Vegetarian Myth_ says it best:
> Why should people in Cambodia be dependent on the US for their basic sustenance? It condemns them to participating in a market economy where they will have to dedicate their labor and local resources to produce raw materials, like timber and metal ore, or cheap consumer goods like sneakers or computer chips, for rich nations. With the pennies they get in return, they will then have to buy food from the same rich nations or their progeny, the grain cartels. This is a destructive, inhumane, and oppressive arrangement. I have to believe that the political vegetarians haven’t thought it through.
