I would similarly adore to watch the Planned Barrenhood fall, but promotion of birth control is not the way to do it. The abortion industry and the contraceptive industry overlap in many cases, and PP makes a killing (in more ways than one) by selling contraceptives and abortifacient birth control.
Since a majority of women who have abortions say they were using birth control when they got pregnant, we can safely say that contraception does not prevent abortion. On the cultural front, such widespread use of contraceptives has separated sex from procreation to a point that people are shocked when the sexual act is successful in its biological objective of creating a human being.
In one of my undergraduate courses we talked a lot about gender, family, all that cliche college stuff, and during one class discussion about sexual and reproductive issues, I could see the wheels turning in my classmates heads when I pointed out that sex makes babies. They conceded that that could, in fact, be true, but had so lost any semblance of common sense that they could not draw a cause-and-effect conclusion from their knowledge of where babies come from. This is the result of growing up in a generation so surrounded by reproductive technologies and non-procreative sex, that the process as it occurs when medications and devices and surrogates and sperm donors are not present is confusing to them. I, personally, find this mechanization of relationships, physical intimacy and family; and its disenchantment with the mystery of human origins, sad.
