How about parents "and" schools teach sex education plus easier access to contraceptives. Oh, I forgot the pope is against contraceptives so Catholic Schools and Catholic Parents will not be providing contraceptives or even talk about them. 
Schools can and do teach fertilization and fetal development as part of sex education. I can talk to both sides having attended Catholic grammar school and public high school. How about schools teaching sex education so when students grow up they can teach their kids about it intelligently?
