Additional consideration to the cross-species comparison consideration:
In comparing human to animal charities, we’re often comparing human years lost (with DALYs or QALYs) to improvements in quality or years of negative life prevented. There’s lots of scope for disagreement in making these comparisons.
E.g. is a year on a factory farm worse than a year of an average human’s life is good? If so, by how many orders of magnitude? I’d guess it is worse, perhaps by an order of magnitude or more.
See here for more discussion (though it’s quite an old post and Kelly has told me she would change / update sections of it, given the time).
