This is a fascinating analysis, but if I understand it correctly, you are estimating the impact of fishing and agriculture on average wild animal wellbeing (which you estimate by its effect on the death rate), not total wellbeing, as the first sentence of your post states. Is that correct?
This seems important, as I don’t think there are many who would defend the idea that average welfare is what matters in population ethics? So I’m not sure how important the considerations you point out are. The change in population size seems like it’s going to be the much more important effect here.
It also doesn’t seem obvious to me that we should be able to estimate the impact of fishing or agriculture on average welfare purely by its impact on the death rate. Aren’t there lots of other ways they could impact wild animal welfare too (e.g. by changing the cause of death for wild-animals)?
