The no-meat furore is a bandwagon eagerly jumped on by the more evangelical veganistas. We shouldn't be rearing meat on land that can grow food crops, or which supports rain forest, and we shouldn't be growing half our cereal crops (as we do in the UK) for animal feed. But that still leaves a lot of land that is far better suited for animal-rearing than for crop-growing. Mountainous or hilly areas, or land with thin or rocky soils, or land that is difficult to irrigate all lend themselves to animal husbandry. In poorer countries, animal manure may provide most or all of the fertiliser for subsistence farmers, chemical fertilisers being both far too expensive and far too ruinous of the soil. It all means less meat, but not no meat. And we do have omnivore teeth and guts.
