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!
I work at Wild Animal Initiative. Lack of funding is a major constraint on the movement right now, so donating is a great way to make an impact. The main organizations working on wild animal welfare currently are Wild Animal Initiative, Rethink Priorities, and Animal Ethics.
If you're moved to pursue a career in wild animal welfare research, a computer science background may be more useful than you think. Your experience could be the foundation for a graduate degree in bioinformatics, population ecology, evolutionary biology, or climate science, for example. Computer scientists could contribute to the field by improving wildlife monitoring technology, making code-heavy data analysis tools more accessible, or developing tools for organizing and sharing research about wild animal welfare.
Whatever you end up doing, it's great that you're interested in helping wild animals. If you want to chat more about how you can apply your talents to this cause area, feel free to reach out!
I appreciate your comment! I'll reach out to you.
