Huge Reduction in Meat-Eating 'Essential' To Avoid Climate Breakdown (theguardian.com)

Huge reductions in meat-eating are essential to avoid dangerous climate change, according to the most comprehensive analysis yet of the food system's impact on the environment. From a report: In western countries, beef consumption needs to fall by 90% and be replaced by five times more beans and pulses. The research [PDF] also finds that enormous changes to farming are needed to avoid destroying the planet's ability to feed the 10 billion people expected to be on the planet in a few decades. Food production already causes great damage to the environment, via greenhouse gases from livestock, deforestation and water shortages from farming, and vast ocean dead zones from agricultural pollution. But without action, its impact will get far worse as the world population rises by 2.3 billion people by 2050 and global income triples, enabling more people to eat meat-rich western diets.

We know that in most cases we get about 1 pound of meat from an animal for every 10 pounds of plants we put into them, and that's completely ignoring the economic costs of getting the plants to them and everything else that goes in to that.

    We may recall that for a while we tried feeding the fattiest part of the cows back to other cows to speed up development, it turned out that didn't work out very well (economics not even considered in that part).

It's used for pasture, hay, and feed grain because you throw stuff out there and then go crudely harvest it. Pigs will eat corn cobs, so you can just dump an entire uprooted corn plant in front of the pig and that's that.

    That land isn't economically-viable for food production: you'd have to use a hell of a lot more irrigation, fertilization, and pesticides, with lower yields despite all that, plus more human investment. The amount of greenhouse gas and runoff involved per unit food produced would be massive. Instead, we'd pave over it, build cities, and employ the labor in new factories--assuming we could find a way to feed people.

    It has been observed that some regions grow beef entirely on waste byproducts, with 100% of their feed coming from corn stalks, wheat stalks, and the like. More often, it's that plus pasture. Irrigation and fertilization of feed crop is either not used or not used as intensively as for produce, and the use of cover crop also provides an alternative to moisture retention, fertilization, and weed control: legumes add nitrogen to the soil between crop cycles, vetch crowds out weeds aggressively, and any dense cover planting (including plantings during crop growth) retains moisture. Such cover crops also provide feed and forage for livestock.
