Good question -- "But a crucial question to ask is: which animals need our help most?"
"The number of wild animals vastly exceeds that of animals on factory farms, in laboratories, or kept as pets." ( https://infty.xyz/#/en/@/split/topic/94 )
Looks rational. Curious to know, what the program really offers. Economically, any activity is just a conversion of one type of assets into another. A charity is essentially converting money into -- e.g., a world without poverty, a world without animal suffering, etc., and in a sense, it's selling the world... and it is still a trade, just trading the delta of the distance to the goal...
What I worry about, is that while EA heavily relies on well-known statistics alone, and it does not as much rely on as-of-yet unrejected hypotheses that follow from well-founded creative reasoning, that requires that little bit of financial support and effort to verify and generate data.
