In an early game about turn 20 with 2 colonies Earth and Mars. Earth has two farms and produces four food. Total food consumption of both planets is 3 food so my stockpile shows 1 food. My question is, is this number at the top a stockpile because it doesn't change from 1. I was hoping it would increase every turn and I could build a city but it appears I'm missing something about how food works.
Thanks in advance for your response!
