utility has several virtues, but i agree that it’s not the end-all/be-all. strictly speaking the “point” of any living thing is to pass it’s genes by reproduction, but in a complex and evolving world there are lots of animals that have a “point” in existing. oysters filter water, worms enrich soil, birds spread seeds, bees pollinate flowers, there are primary decomposers and secondary decomposers and tertiary decomposers and some birds build nests in trees and squirrels hide nuts and, you get the picture?

then there are other animals that we have changed for their utility. cows, pigs, chickens, and sheep are delicious and they would not make up such a share of modern biomass if we didn’t industrialize their slaughter. in some cases the point of an animal is that we’re gonna eat it.

if you’re an emotion-forward person you might think “oh, no, that’s terrible!” and you’re allowed to feel that way but usually things are the way they are for a bunch of reasons. feelings are great but food security is better. utility also has a role to play in conservation: we’re having a great time with industry but if the earth suffers catastrophic ecological collapse, the whole party stops.
