The meat-eater problem wonders whether making poor humans richer could have significant negative consequences for non-human animals because of increased meat consumption as people become richer. With some sets of parameter values (for inter-species comparisons, market elasticity, consumer behaviour etc) this could mean making humans richer is morally net negative.

I am wondering about an analgous issue whereby the prima facie good thing of reducing the extent of animal agriculture will increase the amount of wilderness in the world, thus increasing the amount of wild animal suffering. Again, depending on how the lives of farmed and wild animals compare, this could mean reducing animal agriculture is net bad.

I find both of these propositions intuitively repellant, I think because I am used to thinking about direct consequences rather than flow-through effects. My immediate worry is that these concerns are generated by motivated reasoning of people not wanting to donate money to GiveWell or be vegan. (fyi I have donated to GiveWell and am mostly though not entirely vegan.)

However, I think they both deserve to be addressed on their merits.

There has been significant discussion of the meat-eater problem, but I have not seen any of the wild-animal equivalent. Could someone direct me to some work on the effects of animal agriculture on wild animal welfare? Alternately, what do you think? If one's view on whether wild animals have net-positive lives turns out to be a crux for whether ~veganism is morally obligatory, this seems important. If you are a relatively ardent vegan for whom this concern does not seem important, I am curious to here why.

In a recent event launching the NYU Wild Animal Welfare Program Jeff Sebo made a passing remark on this sort of issue:

If anyone ever tries to use wild animal welfare as a reason not to end factory farming and animal agriculture because 'oh plant farming harms wild animals' yes it does, and we shoud care about that, but animal agriculture uses more land and requires more plant farming and therefore more wild animal deaths in plant farming than plant based agricultrue does, so please push back against that argument when you encounter that.

If you are reading this Jeff, my worry is a bit different: not that agriculture harms animals directly (though yes of course that is terrible), but that land that is not used for agriculture will be used by wild animals, and I have significant credence in the wild being a bad, perhaps very bad, place to live as the average animal.
