Of the total area that is used by humans (Agriculture, Urban and Built-up Land),
- urban and built-up land is 1m km²,
- agriculture is 48m km²,
so agriculture is 48 of 49 millions km² used, that’s 98%. The remaining 2% are all streets and housing and other infrastructure together.
This chart also shows how terribly inefficient animal farming is.
Most pasture land isn’t suitable as farmland - there’s examples of overlap of course, but you really can’t draw that conclusion from the chart, it leaves out far too much information.
This is true. But at the same time, the tradeoff I think more about isn’t pasture versus crop land, but pasture and crop land versus wild land. Personally, I really enjoy eating meat, and have no problem with its production in general. But I also think that we should reserve far more land for nature.
Imo, a good way to strike the balance is via pigouvian taxes. First, of course, a carbon tax. Animal agriculture creates a lot of carbon, so higher prices would drive consumers to lower-carbon alternatives. Then a land value tax - the trick would be deciding how much the intrinsic beauty of nature and access to it by the public is worth - but once we figure out a decent number, the scheme should work quite well. If you want to farm/ranch, you aren’t allowed to use up everyone else’s nature for free. Either generate enough money to pay the public back for using their nature, or bounce. And of course, better rules and oversight for animal welfare - I wanna eat meat, not meat produced with unnecessary suffering.
This combination of approaches would reduce meat consumption and land use in a fair and ethical way, while still not being overbearing or playing favorites by doing things like banning x or y. Unfortunately, this is very much a pipe dream - at least in the US right now, as we have, umm… more pressing issues.
If we stopped hurting animals we could rewild a lot more land. All that pasture, boom, back to the wild. Then, all the farmland used to grow feed for animals, split it up into what is necessary for human flourishing and then the rest can also go back to the wild.
That’s the efficient use of land to feed the maximum number of people while maintaining the maximum wild acreage.
If we stopped hurting animals
So you’re saying “if everyone went vegan/vegetarian…” And I have a lot of doubt about the practical viability of this plan. People have been eating animals longer than we’ve had money or governments… or fire. So I’m betting it would be a bit of a tough habit to break. Development of affordable lab-grown meat could go a long way - but my bet is that there will be subtle (or not so subtle) differences between lab grown and real meat for quite a while, and there would be an indefinite market (maybe luxury, maybe just middle class) for real meat for the forseeable future.
Hence, rather than relying on people to voluntarily reduce meat consumption (they won’t) or applying heavy-handed and clumsy tactics (banning meat, deciding who or what is worthy of meat and when), we simply apply a price signal and reasonable regulations. The animals live relatively happy lives in reasonable and sanitary conditions. Then one day they wander down a hallway and are popped in the forehead with a bolt, and that’s it. Then the levers of prices can be pulled to gradually push peoples choices in long-term pro-social directions - gradually reducing meat consumption over time in whatever way makes sense to them, while wild land increases and carbon emissions decrease.
It’s interesting that you think prices are voluntary.
If meat is too expensive for poor people to eat, then it’s the same as banning poor people from eating meat.
I don’t think I said that? But using price incentives allows people to make the choice between spending their money on the same amount of a now more expensive good, or to change their behavior somehow. Hence, a poor person who previously ate beef every day has a number of options such as eating beef only on certain days of the week, eating a smaller portion of beef each day, or eating a less expensive kind of meat.
If we recognize that meat production has negative externalities, then to reduce these externalities we need to reduce meat production, which will necessarily reduce meat consumption. Above you seemed to be implying that the ideal solution would be cessation of meat production entirely - which I have to point out, would also result in poor people being unable to eat meat. So, are you defending the right of the poor to eat meat, or do you want to take the meat off their plates?
Really I assume that what you are getting at is economic fairness, which is not something I bothered mentioning because it didn’t seem relevant to the point I was making. But anyway - pigouvian tax schemes are often paired with social benefits. The government uses the taxes raised to either facilitate the social change it wants to create (eg, using a carbon tax to fund transit improvements) or returns the funds to citizens directly as a dividend which offsets the cost of the increased price of goods (in this case, there would be a break even point somewhere around lower middle class where the dividend recieved would be greater than the increased price of meat).
Again, price “incentives” are just a ban for poor people. A poor person who can’t afford beef is banned from eating it. It’s basically illegal with extra steps, because they can’t afford to buy it and the only alternatives are illegal.
If we’re going to ban meat we should apply the ban equally and fairly, instead of just banning poor people.
Okay, but can we stop using suitable farmland to grow corn cattle feed?
Most of the corn cattle are eating is the stalk and husks. The stuff we’re going to grow regardless and would otherwise throw away.
Near slaughter when they get fattened up on feed lots (called finishing) it’s mostly cracked corn grain, it’s more towards the beggining of life that they’re fed roughage with only a small amount of supporting grain.
