Abstract
All over the world millions of children are without parental care. As a consequence they are liable to suffer serious harm. I argue the general duty to assist those in need extends to children without parental care and that some people are under a moral duty to adopt rather than have biological children. I defend this claim against the following objections: (1) intimate decisions are excluded from the duty to assist, (2) adopting children is too costly to be required by morality, (3) the duty to assist is a collective duty, (4) the duty to assist is an imperfect duty, and (5) there are, in fact, very few adoptable children
