That wouldn't be need not eat, that would be Supply Bonus. Quite a hefty one, I'd guess
The tribespeople ideas for Oceania sound fun though - I've tried them a few times in singleplayer, and... yeah. They're basically just the indie tritons with a few giant mermen that remind me slightly of Disney's The Little Mermaid. There's nothing -basically- wrong with that, but I'd love to see some more diversity in there and this sounds like a good way about it.
