What component overwhelmingly makes up the ambient Martian atmosphere preventing a newborn infant from breathing it?

Answer

Carbon dioxide

A Martian infant cannot survive by breathing the ambient atmosphere because it is overwhelmingly composed of carbon dioxide. Furthermore, the low atmospheric pressure on Mars is also life-threatening, as it would cause bodily fluids to boil at a normal human core temperature. Consequently, the delivery and initial life support for the infant must occur entirely within a pressurized, sealed habitat, functioning effectively as a highly sophisticated artificial womb for an extended period.
