The neglectedness and intensity of animal suffering would, in a triaging scenario, see me prioritizing it over many global health interventions. I am open to the idea that many animals do actually live lives worth living. That said, I suspect I would rather forego living than spend an existence as an industrially farmed broiler chicken or fish. These are the animals I would spend money on at the margin, with research into the welfare of more liminal animals like crustaceans and insects (probably not large increases for wild for now, since tractability may remain a constraint).
I am sensitive to the idea that animal welfare work may not be able to productively absorb $100 million. At the same time, I would like to see more experimentation with campaigns and approaches in the animal advocacy movement.
No worries Luke! Thank you for your post and for these links.
