So it is OK for nature to kill, and you should do nothing about it?
If God decides to make a woman miscarry at one day, should we do nothing?
What about one week?
What about one month?
What about 28 weeks?
When do we intervene? Or do we intervene? Who decides?
What if a woman miscarries at 15 weeks? Should we do what we can to save it?
I think you misunderstood me. Sometimes women have miscarriages, and nothing can be done about it. It just happens, and it's too late to do anything.
Naturally if a miscarriage can be prevented, it should be.
What an idiotic question. Supposing *nature* did kill, which is can't because nature isn't even a thing,;what WOULD you do about it? Try it for murder? Sue it? How about get a grip.
Miscarriage usually happens because the baby is already dead.
Sometimes, a woman will "miscarry" or deliver prematurely because of dialation or low progesterone. In the earlier case, the cervix is "stitched" and in the latter, bedrest and progesterone are prescribed.
In the case of premature delivery, if a baby can live outside the womb then by all means he/she should be saved. In most of the examples you give however (<28 weeks) this is not the case.
