[Edit 2024-11-05: my views have changed quite a lot since I wrote this. See here.]
This is the story of how I came to see Wild Animal Welfare (WAW) as a less promising cause than I did initially. I summarise three articles I wrote on WAW: ‘Why it’s difficult to find cost-effective WAW interventions we could do now’, ‘Lobbying governments to improve WAW’, and ‘WAW in the far future’. I then draw some more general conclusions. The articles assume some familiarity with WAW ideas. See here or here for an intro to WAW ideas.
My initial opinion
My first exposure to EA was reading Brian Tomasik’s articles about WAW. I couldn’t believe that despite constantly watching nature documentaries, I had never realized that all this natural suffering is a problem we could try solving. When I became familiar with other EA ideas, I still saw WAW as by far the most promising non-longtermist cause. I thought that EA individuals and organizations continued to focus most of the funding and work on farmed animals because of the status quo bias, risk-aversion, failure to appreciate the scale of WAW issues, misconceptions about WAW, and because they didn’t care about small animals despite evidence that they could be sentient.
There seem to be no cost-effective interventions to pursue now
In 2021, I was given the task of finding a cost-effective WAW intervention that could be pursued in the next few years. I was surprised by how difficult it was to come up with promising WAW interventions. Also, most ideas were very difficult to evaluate and their impacts were highly uncertain. To my surprise, most WAW researchers that I talked to agreed that we’re unlikely to find WAW interventions that could be as cost-effective as farmed animal welfare interventions within the next few years. It’s just much easier to change conditions and observe consequences for farmed animals because their genetics and environment are controlled by humans. I ended up spending most of my time evaluating interventions to reduce aquatic noise. While I think this is promising compared to other WAW interventions I considered, there are quite many farmed animal interventions that I would prioritize over reducing aquatic noise. I still think there is about a 20% chance that someone will find a direct WAW intervention in the next ten years that is more promising than the marginal farmed animal welfare intervention at the current funding level.
I discuss direct short-term WAW interventions in more detail here.
Influencing governments
Some WAW advocates promote research on WAW in academia. For some of them, their aim is twofold: to identify effective interventions and establish WAW as a legitimate field of study. The hope is that by gaining greater legitimacy, WAW advocates can influence government policy. For example, governments could control wild populations more humanely, vaccinate animals against some diseases, and eradicate some parasites.
I am somewhat skeptical of this because:
- The argument for the importance of WAW rests on the enormous numbers of small wild animals. It’s difficult to imagine politicians and voters wanting to spend taxpayer money on improving wild fish or insect welfare, especially in a scope-sensitive way. But it could have been similarly difficult to imagine governments funding species conservation efforts until it happened.
- The consequences on the welfare of all affected wild animals seem nearly impossible to determine, even with a lot of research. Also, research in one ecosystem might not generalize to other ecosystems.
- However, this is the same as the concern of cluelessness that applies to all causes. That is, all interventions have complicated indirect effects that are impossible to predict. To me, cluelessness seems a bigger problem in WAW because first-order effects are usually dwarfed by second and third-order effects. For example, vaccinations may increase the population of that species, which could be bad if their lives are still full of suffering. Also, when the population of one species changes, it changes populations of other species too. But overall, I’m confused about cluelessness.
- Even if we determine consequences, people with different moral views might disagree on which consequences they prefer. For example, people may disagree on how to weigh the welfare of different animal species, happiness versus suffering, short and intense suffering versus chronic but less intense suffering, etc. This may eventually divide the WAW movement into many camps and hurt overall efforts.
See here for further discussion of the goals of lobbying governments to improve WAW, and obstacles to doing this.
Long-term future
Others have argued that what matters most in WAW is moral circle expansion and the effect we may have on the far future. But what exactly do we want to achieve in the far future with our current WAW work? In this article, I listed all the far-future scenarios where WAW seemed very important. The most important ones included scenarios where wildlife is spread beyond Earth. For example, we might develop an aligned transformative AI and the humans in charge might want to colonize space with biological human-like beings and animals, rather than machines. In that case, we could end up with quadrillions of animals suffering on billions of planets for billions of years. Compared to that, WAW interventions on Earth seem much less important.
However, to me, WAW doesn’t seem to be the most important thing for the far future - not even close. Digital minds could be much more efficient, thrive in environments where biological beings can’t, utilize more resources, and seem more likely to exist in huge numbers. Hence, some other longtermist work seems much more promising to me than longtermist animal welfare work.
If you think that the future is likely to be good, then I think that reducing x-risks is much much more promising. If you are a negative utilitarian (i.e., you only care about reducing suffering) or you are pessimistic about the future, you may want to prioritize work that aims to reduce the potential suffering of future digital minds instead (for example, the work of organizations like The Center on Long-term Risk). The tractability of trying to reduce digital mind suffering might be even lower than for longtermist animal welfare work, but the scale is much much higher. I think that there may be some worthwhile things to do in the intersection of longtermism and animal welfare but I don't think it that it should become a major focus for EA.
I discuss WAW and the far future in more detail here.
Overall opinion
After looking into these topics, I now tentatively think that WAW is not a very promising EA cause because:
- In the short-term (the next ten years), WAW interventions we could pursue to help wild animals now seem less cost-effective than farmed animal interventions.
- In the medium-term (10-300 years), trying to influence governments to do WAW work seems similarly speculative to other longtermist work but far less important.
- In the long-term, WAW seems important but not nearly as important as preventing x-risks and perhaps some other work.
All that said, I’m unsure how seriously my opinions should be taken because:
- I don’t have an ecology/biology/conservation background to competently evaluate direct short-term WAW interventions,
- I don’t know enough about the history of social movements to evaluate how likely WAW is to succeed as a social movement, and
- I’m not very knowledgeable about longtermism.
Hence, I see my articles on WAW as the start of a conversation, not the end of it.
Despite my concerns, if I was in charge of all EA funding, I still wouldn’t set WAW funding to zero. Since it’s very difficult to predict which interventions will be important in the future, I think it makes sense to try many different approaches. I still believe that WAW is promising enough to do some further research and movement building. For example, even though I think that corporate farmed animal welfare campaigns are very cost-effective, I would not choose to drop all WAW funding in order to fund even more corporate campaigns, because WAW work could open an entirely new world of possibilities. We won't know what's there unless we try.
However, I wouldn’t spend much more money on WAW than EA is currently spending either. My subjective probability that the WAW movement will take off with $8 million per year of funding is not that much higher than the probability that it will take off with $2 million per year of funding, as the movement’s success probably mostly depends on factors other than funding. But with $2 million, the probability would be much higher than with $0 (I’m using somewhat random numbers here to make the point). And ideally, the money that we do spend on WAW would be used to fund people with different visions about WAW to try multiple different approaches so that we could see which approaches work best. I see some of this happening now, so I mostly support the status quo. Of course, my opinion on how much funding WAW should receive might change upon seeing concrete funding proposals.
[EDIT 2023-02-21: I criticized the version of the WAW movement I saw being pursued by organizations. To my knowledge, no organization currently works on WAW by trying to help microorganisms, or decrease wild animal populations (which perhaps could be done in relatively uncontraversial ways). I simply don’t have an opinion about a WAW movement that would focus on such things. There were some restrictions on the kinds of short-term interventions I could recommend in my intervention search. Interventions that would help microbes or help wild animals by reducing their populations simply didn’t qualify. Thank you to the commenters who made me realize this.]
Opinions expressed here are solely my own. I’m not currently employed by any organization.
Great post!
As comments by Max and Vasco hint at, I think it might still be the case that considering effects on wild animals is essential when evaluating any short-termist intervention (including those for farmed animals and human welfare). For example, I remain uncertain whether vegetarianism increases or decreases total suffering because of wild-animal side effects, mainly because beef may (or may not!) reduce a lot of suffering even if all other meat types increase it. (I still hope people avoid eating chicken and other small farmed animals.)
In my opinion, the most important type of WAW research is getting more clarity on big questions, like what the net impact is of cattle grazing, climate change, and crop cultivation on total invertebrate populations. These are some of the biggest impacts that humanity has on wild animals, and the answers would inform analysis of the side effects of various other interventions like meat reduction or family planning.
I haven't followed a lot of the recent WAW work, but my experience is that many other people working on WAW are less focused on these questions about how humans change total population sizes. Researchers more often think about ways to improve welfare while keeping population size constant. Those latter interventions may have more public support and are more accommodating to non-suffering-focused utilitarians who don't want to reduce the amount of happiness in nature. But as you mention, those interventions also seem more subject to cluelessness (is vaccination net good or bad considering side effects? it's super unclear) and often target big animals rather than invertebrates. From this perspective, I think efforts to improve the welfare of farmed chickens and fish may be more cost-effective (though it's still worth exploring wild-animal interventions too, as you say). Research and advocacy of less painful killing of wild-caught fish also seems extremely important, and it's unclear whether to count this as a farmed-animal or wild-animal intervention.
Apart from less painful killing of wild animals (fish, rodents, insect on crop fields), or maybe some other large-scale interventions like reducing aquatic noise, I think the cost-effectiveness of work on wild animals would come from trying to reduce (or avoid increasing) population sizes, via reducing plant productivity. Reducing the amount of plant growth in an ecosystem helps invertebrates (including mites, springtails, and nematodes, which are extremely numerous but also hard to help in ways other than preventing their existence) and is somewhat less subject to cluelessness problems because you don't have to model internal ecosystem dynamics as much -- you just have to reduce the productivity of the first trophic level. But I haven't found a lot of people who are interested in working on population-reduction interventions. This apparent lack of interest in reducing populations is one reason I've done less thinking about WAW in recent years. Another reason is that I respect the efforts of WAW organizations to put a more mainstream face on the WAW movement, and I wonder if my continuing to harp on why we should actually be focusing on reducing populations would seem to them as counterproductive.
I compiled a list of possible interventions to reduce total invertebrate populations that could possibly be lobbied for at the government level in some fashion. Some of them don't seem super cost-effective, but some might be, such as trying to reduce irrigation subsidies, which is an intervention that could be argued for on other grounds as well. Taxing fertilizer and/or water use on crop fields, pastures, and/or lawns might be pretty valuable if it could be achieved. (Some local regions do have subsidies for people who reduce their lawn's water use.) If geoengineering to fertilize oceans ever happens, opposing it would be extremely important, though doing a campaign about that now might be net harmful via increasing the salience of the idea.
(Sorry for being slow to return here!)
Yeah, I think some ways of reducing plant growth are often supported by environmentalists, including
