In the 1990s and 2000s, undercover investigations—from factory farms to primate labs—catalyzed public outrage. Terms like “battery cage,” “gestation crate,” and “force-feeding” entered the lexicon. The welfare movement scored legislative victories (the EU’s ban on veal crates, California’s Proposition 12). The rights movement, meanwhile, focused on litigation, corporate campaigns, and cultural change.

These early laws targeted overt cruelty—bear-baiting, overworking draft horses, brutal slaughter methods. The American SPCA followed in 1866. This was pure welfarism: reducing visible suffering without challenging the economic or social order.

Part V: Where the Lines Blur – The Three Pillars of Modern Animal Ethics In practice, most people occupy a mixed position. Few are pure abolitionists (refusing all animal products, including medication tested on animals). Few are pure welfarists (accepting any level of use as long as it’s “humane”). Instead, contemporary animal ethics rests on three pillars:
