Sometimes Foer condemns animal farming for reasons that appear to have more to do with anti-capitalist ideology than the environment. The “economics of the market inevitably leads toward instability,” he writes.68 Such a logic leads Foer to attack farmed salmon as worse for the environment than wild salmon, even though, as we saw, not only are farmed salmon of equal nutritional value as wild salmon, they substitute for wild salmon, and open up the potential of reducing overfishing, one of humankind’s largest, and least-discussed, impacts on wild animals.
