Would you suggest that we should stop having children entirely, or not as much?
Would you also put in place a mandatory sterilisation program for people to stop having children?
Given that it is easier to have no children then there is simply no need to have them! It is now 2019, we don't have subsistence farming, so we don't have a need for children to toil in the fields. There is no need for mandatory sterilisation as we now have effective contraception and safe abortion if necessary.
