The natural equivalent would be contraception for wild animal. A practice that holds significant promise.
I think controlling the fertility of rodents can easily increase or decrease welfare. I believe it may impact soil animals way more than rodents, and I have very little idea about whether it increases or decreases the welfare of soil animals.
While many people try to help birds by using bird-safe glass, providing nesting boxes, or feeding them during winter, the downside is that an artificially inflated population can negatively impact the birds themselves and the insects they hunt.
No. I think I would guess random animals of many species to have negative lives with a probability of around 50 %, including species of nematodes. In addition, I do not expect the uncertainty about whether animals have positive or negative lives to be super correlated across species. So random animals of some species having positive lives would still leave me believing that random animals of some other species could easily have negative lives.
I asked to confirm because the page is not technically a paper.
I very much agree.
