But the environment (and animal welfare) is still worse off in post-industrial societies than pre-industrial societies, so you cannot credibly claim going from pre-industrial to industrial (which is what we generally mean by global health and development) is an environmental issue (or an animal welfare issue). It’s unclear if helping societies go from industrial to post-industrial is tractable, but that would typically fall under progress studies, not global health and development.
