Im pretty sure you missed the point of the entire movie.
Abortions make human life a disposable thing. Children of Men points out the extreme value of human life and why it should never be thrown away.
The scene where Clive and the girl are walking out of the building being attacked near the end, both sides stop fighting to marvel at the miracle of life.
This is the point! Life is not disposable and should never be thrown away.
