I suppose my final take on the matter is that Abortion is not contraception, it shouldn't be used instead of contraception, it's potentially dangerous if done too often, and a great deal needs to be done to stop it being viewed as a form of contraception.
That said, a lot of the reason that it is used as contraception is because of poor Sex Education, difficulty in obtaining proper contraceptives etc. It's there that the problem needs to be attacked, to deal with this crazy Dogma over the use of contraceptives, the acceptance of such preventatives would do so much good around the world as far as dealing with STD's abandoned/murdered babies, overpopulation etc and if it were not for the ridiculous taboos put in place by certain religious establishments, simply because they want the Church to grow, the situation, I feel, would be markedly better in places like Africa.
