I'm interested in wild animal welfare as one of many potentially top-priority causes. Currently, the field seems immature: we know very little about how to improve wild animal welfare, so the best thing that anyone can do right now is do research on welfare biology. But I'm not a biologist, so I can't really contribute to welfare bio (although I'm a computer scientist with some exposure to comp bio, so I could contribute to "computational welfare bio"). In general, how can non-biologists contribute to the wild animal welfare cause?
At a risk of telling you something you already know, you could donate to the Wild Animal Initiative, a charity working to build the academic field of wild animal welfare. WAI is a top charity according to Animal Charity Evaluators.
You can also spread the word about the problem and try to contribute to expanding humanity's moral circle.
I'm sure there are some useful things a computer scientist can do to reduce wild animal suffering, but I'm not the person to advise on that. On a slightly tenuous note, it seems possible that working on AI alignment could be good for wild animals in the long-run, as a superintelligent AI could help us reduce wild animal suffering.
Probably not the answers you were looking for, but hopefully this wasn't completely useless!
On an even more tenuous note, as a computer scientist you may be well-placed to help build an artificial sentience movement. I admit this might seem a bit random for me to have brought up, but if you care about wild animal suffering you may also care about the the possibility of artificial sentience suffering in the future, which is a realistic scenario. There may be clearer ways for a computer scientist to get involved in artificial sentience than wild animal suffering. I also happen to know that there are some discussions being held within EA about kicks... (read more)
