That's a fantastic question, and here's another area where Canada has stepped forward, introducing the UN resolution on early and forced child marriage.
The most detrimental effect on a young girl is that she dies, and this is a tragedy. This is about young children being forced into marriage, becoming pregnant early, and having babies at such an early age that the body is not ready for it, simply the size of the pelvis. For example, the labour gets obstructed, there's no access to Caesarean section, and the girl and the baby die. To my way of thinking, there's no greater deprivation of human rights than the right to life.
To answer your question, then, that is the worst outcome of early, forced, child marriage, and it creates a cycle that really leads to the root cause of many of the maternal and some of the child deaths in the developing world. I heard some evidence that a significant minority of the maternal deaths can actually be attributed to young pregnancies, many of which are related to child marriage.
I think that was your first question. You had a second one.
