Animals < Humans < Nature?
Teaching undergrads, I often come across the following curious combination of views:
Speciesism: We should strongly favor humans over non-human animals, to such an extent that we should donate to human charities over animal charities even if the latter turn out to be orders of magnitude more cost-effective at relieving suffering.
Ecological Anti-humanism: It would be a good thing if humanity went extinct, because we’re a scourge on the planet; nature would be better-off without us.
It isn’t strictly logically inconsistent to devalue individual animals while venerating “nature” more broadly. But it does seem odd! I guess kids are enculturated with lots of ecological anti-humanist propaganda, so it’s a familiar message that resonates with many. Singer-style concern for the suffering of non-cute animals, by contrast, is a much more foreign idea and hence prone to be dismissed as seeming “absurd” on initial exposure.
We live in a strange moral culture.
Thanks for the post, Richard.
I would be curious to know your thoughts on my post Saving human lives cheaply is the most cost-effective way of increasing animal welfare?. I estimate the Centre for Exploratory Altruism Research’s (CEARCH’s) High Impact Philanthropy Fund (HIPF), which funds public health interventions in low and middle income countries (LMICs), increases the welfare of soil ants, termites, springtails, mites, and nematodes 101 k (= 70.6*10^3/0.701) times as cost-effectively as cage-free corporate campaigns increase the welfare of chickens.
Sorry, I don't think I have relevant expertise to assess such empirical claims (which is why I focus more on hypotheticals). It would certainly be convenient if helping people turned out to be the best way to also reduce non-human suffering! And it could be true (I don't take convenience to be an automatic debunker or anything). I just have no idea.
I suspect you are overestimating the difficulty of checking the empirical claims. I am pretty confident that funding HIPF decreases the suffering of soil animals much more cost-effectively than cage-free corporate campaigns decrease the suffering of chickens. I estimate HIPF decreases 5.07 billion soil-animal-years per $, and that cage-free corporate campaigns improve 10.8 chicken-years per $. For HIPF to decrease the suffering of soil animals less cost-effectively than cage-free corporate campaigns decrease the suffering of chickens, the reduction in suffering due to improving 1 chicken-year would have to be larger than than from decreasing 469 M soil-animal-years (= 5.07*10^9/10.8), whereas I calculate chickens only have 921 k (= 221*10^6/240) times as many neurons as nematodes, which are the soil animals with the fewest neurons. Moreover, I think the number of neurons underestimates the absolute value of the welfare per animal-year. Rethink Priorities' (RP) moral weight project assumes shrimps have 10^-6 as many neurons as humans (see Table 5 here), but the estimate for their welfare range in Table 8.6 of Bob Fischer's book is 8 % that of humans.
For the reasons above, I am also pretty confident that funding HIPF changes the welfare of soil animals much more cost-effectively than cage-free corporate campaigns increase the welfare of chickens. However, I am very uncertain about whether HIPF increases or decreases animal welfare due to being very uncertain about whether soil nematodes have positive or negative lives.
To clarify, I believe researching whether soil nematodes have positive or negative lives would increase animal welfare even more cost-effectively than funding HIPF, but that this still increases animal welfare much more cost-effectively than interventions targeting farmed animals.
I would prefer saving human lives to decrease animal welfare such that soil animals had positive lives. I think saving human lives decreases soil-animal-years, and therefore increases/decreases the welfare of soil animals if these have negative/positive lives. I guess they have negative lives, although I am very uncertain, and estimate the welfare of soil ants, termites, springtails, mites, and nematodes is -977 k times that of humans for my preferred way of comparing welfare across species.
To be clear: I'd be excited for more people to look into these claims! Seems worth investigating. But it's not my comparative advantage.
Good to know! I think highlighting the importance of the topic is one way of getting more people to investigate it ;).
