Each colonist working inside a colony eats 2 food every turn.
Food is one of the most valuable commodities your people produce. The survival of your colonies depends upon it. The best places to grow food are in plains, grasslands, prairie, and savannah. Plowing the land also increases food yield. Fishing is an excellent source of food, and fisheries are particularly productive.
If the stored food reaches 200, it is reduced by 200, and a new free colonist is added. It is possible to export food.
