Comment: Tragically, there are unwanted pregnancies and unwanted children. The foster care system if over flowing, children suffer unimaginable neglect and abuse. Schools should teach sex education - as in p + v = baby - Use condoms. Condoms should be free at every high school, convenience store, drug store. Feature condoms on TV and in movies. 
Maybe things would change if we stop pretending that sex doesn't happen "Not my little girl!" and start making prevention as normal and as open as washing our hands.
