More education, more access to free birth control, more community outreach? I mean, that is all I can think of, to start.
Of course I would also like to see a greater emphasis put on responsible behavior and personal accountability. But I don't know exactly how to make that happen. Sadly, that ship may have sailed.
Obviously nobody wants to have an abortion, at the end of the day. But, without a greater focus on the above mentioned, things are not likely to change much. Relaxing abortion law and focusing on freedoms is not going to help matters in the long run, imo.
