I'm assuming you are being sarcastic, but in case you are not, I think it is a good question.

It seems like having as many children as you want should be a negative human right, up until the point where you can no longer support them and neglect them.

It is a really weird situation though because there are so many social supports in place for children and parents. unwanted children can be put up for adoption. Should there be a limit on the number of times this can be be done by a single individual?

If you have more children than you can properly support and/or care for, you have too many children.

You could ask woman interviewed for this article, she had 4 abortions.
