# Bio Farm

**Number of plots**: 250 

**Income Model**: Resource Purchase & Refill

Special bio-farms have been constructed to serve as a sustainable source of food and oxygen on Carda Station. While in the colonies, you don’t need to worry about oxygen levels. Exploring the outer worlds however is a different experience. We are developing some survival/resource management aspects as part of Exploration and one of those resources will be oxygen. For those long excursions off colony, you’d need a tank of O2 to get you through.
