Not likely to be happening....
War, natural disaster, massive injury or illness of family member, a large change in lie or circumstances might be an event that would make a later termination a necessity.
I can imagine that trying to pick up the pieces of a shattered life like after Katrina might make a child a very bad time.
It really has to be the woman's choice.
We live in a society where we don't have large extended family to help out. Being on her own trying to rebuild a home, care for family, suffering a mental breakdown, etc., a woman would not be able to do all thing for all people, or herself, while pregnant.
Everyone has seen the images of the refugees risking life to get to a safe place. Can any woman imagine taking a long arduous risk like that while in the later half of a pregnancy? Even getting out with a small child must take so much out of any parent.
My daughter gave birth during a hurricane. The hospital had power but when she was released we had not water, power, access to bank, limited food, little gas for the car, no way to clean clothes. We managed pooling resources together, but it really could not have happened at a worse time.
If someone become homeless in a store like that, had to clean out or rebuild a home it would make it near impossible to do while pregnant.
I was near late in my seventh month when I have to deal with a massacre and between the smell, rats disease, sanitation and such meant I was risking both our lives. Not my choice, but it had to be done. I managed to return home before I could not longer travel. I would not have wanted to give birth in those conditions.
You can't know what is ahead and that everything will go as planned. You have to make hard choices for yourself, your fetus and other people. Sometimes saving someone else's life means risking the fetus or even loosing it.
It really has be decide by the woman.
