Broken balance; organic resources and personality traits

[vostok]

2 questions for modders;

1) is there a way to modify the game such that populations require nutrient intakes? As it stands, the only (limited) bonus for large populations is a scanty production bonus. Organic as a resource is irrelevant except for a few specialty components and weapons; one might only build a farm or two during the whole game. Id LIKE to make organic resources be consumed by pop (and then make pop bonuses much larger), but this seems impossible...

Oh, and do the personality traits have any utility at all in the game? As in "serene", "neutral", "impulsive"; they seem empty descriptions that influence nothing.
