You appear not to have understood my point. Directing readers to various norms that have changed over time does not in and of itself provide evidence that this norm (whatever it may be; in this case, the norm that it's ok to eat meat) is going to change. That's a mistake in logic, not good for a wannabe philosopher. There are plenty of examples of people advocating a minority position that is against the norm whose desired change in norms has not happened. It's a non-argument. The whole of that piece is a non-argument really, with some unexamined ageism thrown in for good measure.
Needless to say, I don’t think you’re representing the article accurately. They never say any
particular norm change is inevitable and the focus isn’t really even to say that any given norm change is desirable now, but rather to draw attention to some of the cognitive biases that prevent people from being receptive and open to
arguments for norm change. I'd hope that even if we disagree on the vegan issue we'd agree that broad mindedness and self-awareness is important for moral progress.
'the meat industry' is premised on the growing of animals in order to kill and eat them. When you turn that into 'systemic disregard for animal life', you are adding your own layer of commentary. Not sure you're aware that you are doing this. You've dodged previous questions about Temple Grandin and her work on abbatoirs. Is she wrong? Is she deluded? If so, why and how?
Killing somebody to make money from them shows disregard for their life. An industry built around killing large numbers of individuals to make money from them shows systemic disregard their lives. Can't speak to Grandin's motivations but her reform recommendations are concerned with improving animal
welfare not showing any regard for animal
life as such.
Mad that we've been through this so many times and you still appear not to understand farming.
(1) No they really aren't with the possible exception of hay/silage. Almost all ruminant feed is indigestible to humans. Its pig and poultry where the overlap is strongest.
(2) There's loads of deliberate killing in plant agriculture
And whilst this is a vegan morality - it is not higher or more superior to those who consider eating animals as food, because lots of animals do this. This is where the ego of the author (and yours) come into play. I've never said anybody who is vegan shouldn't be, but yet your religion considers me amoral and subhuman.
(1) How is that relevant to my point? Hay still has to be harvested and field animals will die as a result of the harvesting. Incidentally, a
paper published just over two decades ago calculates that a diet (in the US) based on plant proteins would result in fewer wild animal deaths than even a omnivorous diet based
only on consuming ruminants (and this calculation does not even factor in the issue of deaths for supplemental ruminant feed):
Davis suggests the number of wild animals killed per hectare in crop production (15) is twice that killed in ruminant-pasture (7.5). If this is true, then as long as crop production uses less than half as many hectares as ruminant-pasture to deliver the same amount of food, a vegetarian will kill fewer animals than an omnivore. In fact, crop production uses less than half as many hectares as grass-fed dairy and one-tenth as many hectares as grass-fed beef to deliver the same amount of protein. In one year, 1,000 kilograms of protein can be produced on as few as 1.0 hectares planted with soy and corn, 2.6 hectares used as pasture for grass-fed dairy cows, or 10 hectares used as pasture for grass-fed beef cattle (Vandehaar, 1998; UNFAO, 1996). As such, to obtain the 20 kilograms of protein per year recommended for adults, a vegan-vegetarian would kill 0.3 wild animals annually, a lacto-vegetarian would kill 0.39 wild animals, while a Davis- style omnivore would kill 1.5 wild animals. Thus, correcting Davis’s math, we see that a vegan-vegetarian population would kill the fewest number of wild animals, followed closely by a lacto-vegetarian population.
Another paper, published in 2007, shows that many of the field deaths that have been misattributed to harvesting equipment turn out to be caused by
prey animals. Not denying that many animals die horribly in plant agriculture, but the number has been inflated by various pro-meat scholars and advocates as a stick to bash vegans with.
(2) Yes, there's deliberate killing in plant agriculture, I dealt with that in my point (3) - whilst I'd like to see it reduced and ideally one day eliminated I think its widely accepted in the human context that defensive killing is easier to justify than offensive killing. It's why some people are convicted for murder and others are acquitted for self-defence.
Again, this isn't to justify all forms of field animal killing - some of which is completely unjustified and unnecessary. But as a consumer, when you're making purchasing decisions, you are pretty in the dark about how many any particular plant product was procured (this recent
paper suggests we lack even basic reliable data on field animal deaths in agriculture more broadly) . By contrast, you know with certainty that the meat involved killing. If you think killing animals for food is bad and you're confronted with two products - one you know involved killing and one that may have - then you are not a moral hypocrite for choosing the latter.
On your final point, I think it's strange to base human morality on what other animals do. Some animals eat other animals. So what? Dogs sniff each others' butts in the park, I don't think that's necessarily a good reason for humans to do it too.
