Human-miscible biosphere

Human-miscible biospheres are those in which some substantial portion of the native life is biologically compatible with human nutritional needs. Th e local plants and animals may not be tasty or terribly nourishing, but they can support life without the serious importation of Terran crop seeds and livestock.

Even the friendlier human-miscible biospheres often lack the wide variety of edibles that evolved on Earth, and the natives often supplement their stocks of local foods with limited Terran agriculture. Exotic foods, spices, and liquors can be worth interstellar importation to feed the hunger for novelty on these worlds.

Unfortunately, the fact that humans can eat some native life means that it is very likely that some native life can eat humans in turn. Large predators and diseases capable of human infection are by no means uncommon on these worlds, and small colonies can be hard pressed to survive them.
