The costs are minimal compared to children being bought up in wrong environments, causing any number of issues further down the line for the kids or parents. In a lot of circumstances, getting an abortion is the responsible thing to do, so it’s funny you mention that word.
I don’t think the problem is lack of sex education

Do you think the unplanned pregnancies are from people who don’t understand contraception?
The simple fact is there are so many possible reasons why a couple, or a woman, decide to get an abortion. Trying to put it down to lack of responsibility or eduction is actually insulting.
