Factory farming will stop at some point in this century80%, while human civilization could stay for a much longer time. So you can push humanity in a slightly better long-term direction by improving the circumstances in the third world, e.g. reducing the chance that some countries will want to acquire nuclear weapons for conflict because of wars because of famines.
So there’s an option to affect trajectory change by giving to global health, but not really for animal welfare.
Argument in favor of giving to humans:
