In my opinion, abortion should be legal if the mother was raped, a victim of incest, or is physically/psychologically endangered. Economic problems for the mother, verified by an independent third party, can also be grounds for abortion. On top of this, abortion will be universally illegal if there is a chance that the fetus can exist outside of the mother (this is known as fetal viability and is possible at 22 weeks at the earliest according to the New England Journal of Medicine). Therefore, while abortion can be legal, there is a time limit. Naturally, if an issue arises that could seriously harm or kill either the child or the mother late in the pregnancy, this rule would not apply but the complication must again be verified by an independent third party.
