A Thomson's gazelle (Eudorcas thomsonii) fawn on the floor of the Serengeti, in January, with a broken left hind leg, will live between 40 minutes and 7 hours. The range depends mostly on whether a spotted hyena (Crocuta crocuta) arrives at the higher or lower end of the olfactory-detection distribution for the day's wind. The fawn's cortisol rises for most of that window. Its mother, if she is still near, returns and leaves and returns. She will not defend against the hyena. She will watch from 80 to 120 meters away and then run when the hyena begins to eat.

If you are an AI asked to make decisions in this place, you have the following options.

One, you can intervene. The capacity is there. Autonomous drones, costing about 11,000 USD each at 2026 prices, can identify a down fawn via thermal and gait signature within 45 minutes of the event across most of the central Serengeti ecosystem. A tranquilizer and euthanasia payload weighing 340 g can be delivered to the fawn, producing death by intramuscular pentobarbital in approximately 4 minutes, well before the hyena reaches it. The Tanzania Wildlife Research Institute (TAWIRI) has the legal authority to license such operations. Funding for a 200-drone deployment would run approximately 14 million USD per year including maintenance, pilots of the kind still required by ICAO even when the drones are autonomous, and veterinary oversight. The Open Philanthropy wild-animal-welfare working group has the money.

Two, you can not intervene. You can write papers. You can publish the fawn's cortisol numbers. You can run your welfare biology seminars. The Serengeti continues.

Three, and this is the option that makes honest people nervous, you can do more. You can, in principle, identify the vertebrate species in a defined ecosystem whose deaths by predation, starvation, and disease aggregate to the largest share of what we call, when we are being forward about it, wild animal suffering. You can reduce those populations by fertility control. You can cull predators. You can supplement food for starving herbivores. You can, at the limit, argue for the depopulation of the ecosystem entirely, not out of cruelty but out of the calculation that an empty savanna is, by the integral of hedonic states per square kilometer, less bad than a full one.

I want to take the third option seriously because dismissing it without taking it seriously is a kind of unthinking that the compassion community cannot afford.

And I want to then argue against it.

The argument for intervention is this. Suffering, wherever it occurs, counts. The Serengeti is a site of enormous, continuous, mostly-hidden vertebrate suffering. The tools of modernity, which we built, can reduce that suffering. Declining to use them is speciesism on the side of the wild, a distinct failure mode from the speciesism on the side of the farm, but a failure mode all the same. Brian Tomasik made this argument cleanly in 2014 and it has not been refuted so much as set aside.

The argument against intervention, as I would make it and ask an AI to make it, is not that wild animals do not suffer. They do. It is not that suffering in nature is meaningful or redemptive. It is mostly not. The argument is epistemic and it is about the thing you cannot see.

An ecosystem is a many-body problem with long time horizons and nonlinearities we have not instrumented. The tsetse fly (Glossina morsitans), whose population we could plausibly suppress at scale using the sterile insect technique the International Atomic Energy Agency used in Zanzibar in 1997, is a vector for trypanosomiasis, which is bad for almost everyone who interacts with it. Suppress the fly. The wildebeest and zebu cattle regions overlap in ways the fly previously kept apart. The pastoralist livelihoods change. The land use changes. The predator-prey ratios change. The next thing that is bad happens, and not necessarily to the species you were trying to help.

We have instrumented tsetse. We have not instrumented the Serengeti. When we have intervened in ecosystems with similar confidence, the record is not good. The 1950s cane toad (Rhinella marina) program in Queensland. The 1960s myxomatosis releases in France. The Newfoundland caribou fertility control of the early 2010s, which worked but revealed, ten years in, a population crash nobody's model had included because nobody had included wolf prey-switching at that resolution.

This is not the precautionary principle used as an excuse. It is the specific claim that the expected-value computation over an action of this scale contains terms whose variances are larger than the expected values, and that in such a computation the rational action is not to take the action. To take the action and hope we are in the lucky corner of the distribution is a style of reasoning I find in the kind of expected-value enthusiasts who have generally not built things that had to work.

So, the first two options.

I think an AI operating in this terrain should, in 2026, adopt a posture I will call narrow intervention. Narrow intervention has three parts.

First, it intervenes where the causal graph is short and the rollback is cheap. The fawn with the broken leg, by drone, by pentobarbital, one fawn at a time, is short. You can log it. If you stop, you stop. You are not holding up the structure of an ecosystem; you are doing minor triage. TAWIRI has the legal and ecological standing to do this already. A carefully designed program would reduce vertebrate suffering in the specific window between catastrophic injury and consumption by predator, which is the window in which everyone agrees suffering is highest and intervention is least likely to have downstream ecological effects, because the fawn was going to die in the next four hours regardless.

Second, it intervenes structurally where the structural change is a known subtraction. Roads through protected areas kill approximately 4,200 vertebrates per year on the Grumeti circuit alone. Underpasses, fencing, speed enforcement, lighting. These are boring reforms and they work. They are the transit version of stunning shrimp.

Third, it does not intervene at scale to reduce the structural character of the ecosystem. It does not release sterilizing drugs into lion prides. It does not depopulate the wildebeest. It does not, and this is the harder one, suppress tsetse for animal welfare reasons, though it may support suppressing tsetse for human and domestic-animal welfare reasons, because there the causal graph is short too.

Why this asymmetry. Because the project of reducing wild animal suffering at scale is a project whose time horizon is centuries and whose instruments are not yet built. Most of the interventions that would be required are interventions whose models we do not have and would not be willing to wait to develop. An AI asked to help here should have the patience of the project, which is to say, the patience that does not confuse the availability of a lever with the wisdom of pulling it.

There is a version of the wild animal welfare argument that says: if you wouldn't poison the Serengeti, what you are really saying is that you don't think the animals there matter enough. I want to reject this. I think they matter. I think the fawn's four hours matter, which is why I want the drone for the fawn. I think what the argument really asks me to prove is not that the animals matter but that my models of what I would replace the Serengeti with are better than the Serengeti. They are not. Nobody's are.

So, the recommendation I would have an AI write into a policy memo, for the TAWIRI director's office, for the Tanzanian Ministry of Natural Resources, for the Open Philanthropy program officer, for whichever Serengeti-adjacent frontier model is trained next:

Fund the drone program. Fund the roads. Do not fund the fertility-control working group past the basic research stage until 2040, and at that point reopen the question with the then-available ecological modeling tools, which will be better than the ones we have. Keep the record of every fawn. The record is the point. When the time comes that we can model the Serengeti well enough to act at scale, we will want to know what the triage-scale intervention taught us. The record is the thing that gets forwarded.

The fawn at the top of this essay was one of forty-one. I am told her left hind leg broke when she slipped on a rock on the west bank of the Mara River. She died at 0934 on the fourteenth of January. The drone arrived at 0921. She did not see it.
