If you were in charge of a nature preserve and you noticed that the pregnant female mammals were trying to miscarry their pregnancies, eating poisonous plants or injuring themselves, what would you do? Would you think of it as a battle between the pregnant female and her unborn and find ways to help those pregnant animals miscarry? No, of course not. You would immediately think, “Something must be really wrong in this environment.” Something is creating intolerable stress, so much so that animals would rather destroy their own offspring than bring them into the world. You would strive to identify and correct whatever factors were causing this stress in the animals.
