So why not revolutionize it? We've done so for other major facets of life, so many it would be inane to start to name them. Just look around you.
Anyway, can we not simply start to remove fetuses perhaps w/ placentia and place them in incubators for healthier monitored feeding and resultant growth? At a certain defined stage of pregnancy, before the young woman starts to stretch out to abnormal proportions and emotional distress. And let's not mention the consequences of the final hours, itself. PHEW
Could this be done, in any sucessful way shape or form? Can we beat the way of the animal???

You should go find an obstetrical anatomy book and go look up the structure of the placenta. You'd discover the placenta is an organ actually made up of both maternal and placental tissues. Blood vessels from both approximate in an intimate relationship, yet the blood of the mother and child do not intermix (usually). Miraculously, despite the intertwining of tissues from the two genetically distinct living beings the baby's tissues generally elicit a rejection reaction by the mother's immune system.
We are nowhere near being able to grow an artificial maternal placenta.

Even as implied joke - what exactly do you think that means? Sticking someone in a "cloning machine" and having their baby pop out?

Oxygen and carbon dioxide easily diffuse across a thin cellular membrane very much like they do in the lung. Many nutrients and waste products do too, though some require active transport across the membrane.
Some viruses can cross the membrane too. The seperation isn't always perfect, which may explain how Rh - mothers can become sensitized to their Rh + babies blood.
