Birth control and education, people. That's all it takes.
Make birth control affordable, free to those who just don't have the money, and watch the abortion rate drop.
There's a lot of questions around that. It's true that life begins when the egg and sperm combine to create the zygote, which is the exacting point that a developing life begins. IF birth controls prevents sperm and egg from forming, I would be 100% for cheap and effective birth control.
However, there's also the issue of younger and younger promiscuity. If birth control can be bought OTC, young girls and boys could have rampant sex. And even younger. That, and any young runt of a girl could buy birth control and go out and have sex with an over-age male. I just wish kids and teens could be innocent, and stay out of trouble, but that's more than likely a pipe-dream.
My sensitivity on this issue is that I plan on being a father of at least two little girls in the distant future (someday). I'm scared as hell of having to protect my boys and girls from bad influences, so I reason the best I can do is to keep them occupied and shower them with as much love and attention as I can. Go picking in the orchard, work as a family team in the garden, have icecream night every Saturday and watch a wholesome movie. I don't know.
What I do know is that I don't want my little girls going out at night God-knows-where and having sex with whoever. Girls barely know those young boys, and there's only one thing on the minds of those boys. Sex. Just using them for sex. Young teens (male and female) who don't have proper upbringing whore around and get into trouble. Those bad influence invite alcohol, smoking, drugs, law-breaking, etc. I'd rather have my little girls safe and sound at home, warm, well-fed, safe, and content.
I'm only 25 but thinking about the future and its dangers is enough to give one an ulcer or ten.
