An Argument that Having More Kids is an Obligation

Torbjorn Tannsjo has an interesting, short article arguing that people should have a lot more children.  Apparently, Tannsjo was asked by Vox to write the article.  But then some editors kicked it aside because they thought readers might take his argument to imply that abortions should be reduced, and Vox, I guess, doesn't do anything anti-abortion.  (Nice one, Vox.)  Anyhow, though I disagree in part, it's a neat little essay.
