The "modern appetite for meat" of course depends on the growing number of
people to feed, and on their natural demand for a better, more satisfactory
The cheapest meat used to be that of animals on a different food chain. If
we have deliberately moved those animals on our own, this would appear to
mean that it is more economically efficient to do so than sparing their food
or keeping them out of it.
Of course, this need not mean that it is also the best possible nutritional
choice. Nor that we cannot try and have our steak and eat it too by applying
technology to the problem of producing high-quality meat in the most
efficient possible way, perhaps doing it without full-fledged animals
