While that’s true, it doesn’t mostly have to be sentient creatures, and if some do have to die, at least we can make choices that cause them less suffering.

It’s not simply about utility. Other beings don’t only have value because they’re useful, but because they have complex emotional experiences similar to our own. They can love and suffer and fear similarly to how we can.

But if you want utility, you get that too, since it’s also better for the planet and thus for us.
