Taxonomy is the science of classifying organisms. Animals are divided into the smaller, more recognizable groups phylum, class, order, family, genus, species.
Another way we could classify animals is by the various ways humans abuse them. Most would fit into one of following phylum: Poisoned by humans. Clubbed by humans. Captured by humans. Caged by humans. Shackle-hoisted and stun bolted by humans. Hunted by humans. Consumed by humans, though this category would of course overlap with the captured, caged, shackle-hoisted and stun-bolted categories.
Each of the above phylum can be divided into smaller classes.
Poisoned by human can be divided into the sub-categories, poisoned for human comfort and vanity, i.e. cosmetic testing, and poisoned because humans find their presence annoying (e.g., rodents). Hunted by humans can be divided into the sub-categories, hunted for pleasure, hunted for money, hunted out of fear. Caged by humans can be divided into the sub-categories, caged for viewing pleasure and caged for consumption.
Consumed by humans is of course the largest phylum, comprised of billions of farm animals each year. But there’s hardly an animal on the planet that doesn't suffer some form of abuse, usually culminating in torture and death, at the hands of humans. Taxonomists would have to burn the midnight oil getting them all straight.
