A human. Adult. Can't survive. Without other humans. Providing for them. In countless ways. pffffffft, they can't even drink out of a pristine clean mountain stream without chancing swallowing an amoeba that'll eating them from the inside out. Eat raw meat? They have to process the most basic simplest food items just to be able to digest it without puking their guts out and dying of diarrhea. People in the tropics. THE TROPICS. Would die of exposure if they don't sleep without shelter and a fire to keep them warm. IN THE TROPICS.
Even if it wasn't for the utter fragility that is modern man, the human species bears offspring that are dependent on their parents for the most years of any species to have ever existed ever on Earth.
Yes, survival is not automatic. Brilliant insight.
But it’s possible. If a fetus comes out of the womb in the first trimester or early in the second, it’s not surviving no matter what you do. Later in the second it’s not surviving without modern medicine keeping it alive. Only in the third trimester— the point where abortions are no longer allowed— does it have a reasonable chance of survival and being cared for normally.
