As a utilitarian, my first impulse is to suggest the term "animal welfarism," since it focuses on what I actually care about, namely well-being.
This term maximizes the scope of what one cares about to include both wild animal suffering and factory farming. It also allows for a diversity of actions such as changing one's diet, engaging in political action, or donating money as @Erwin Rossen mentions.
I would also guess that people who identify as animal welfarists are less likely to have the all-or-nothing attitude that it seems like some vegans have.
Ah, thanks for sharing that! She appears to put pretty much everything she has to say behind a paywall, but hopefully, someday there will be a more accessible resource with a similar goal to hers! I'd also recommend checking out the book Early Retirement Extreme. It's, in my view, a foundational text for frugality.
Good idea! I'll look into that! Very sunny from what I've ever heard.
