Is it our right/duty to have children "naturally"?

I've been wondering where people stand on this issue. With the resources of the world being depleted rapidly, and the "first world" using up most of those resources, and the number of children in the world without food, homes, and families - how does everyone justify their choice to have their "own" children? Why do people choose to have their "own" children rather than adopt? Why do people choose to have children in the first place? For my part, I don't plan on having children, but if I did I would choose to adopt - it's a choice that ethically makes sense to me - but I'd like to read the opinion of other people. Amma
