I know that's how it is for Pokémon, but humans too? How did you find that out?

I guess you'd have to bury Pokémon, since you can't eat them. [Yes he's checked.] There have to be some Pokémon that can die though, since the meat here has to come from something. Maybe the graves are for them? Except there shouldn't be anything left to bury if they're being eaten properly. [Does this mean that humans are wasting the lives they take here too?]

Are graves what humans normally make for dead things? I dug one for Grandpa because I don't eat humans and I wanted him to become part of the forest, but is that what humans usually do?
