If a world government were ever formed and they had to choose an age of consent for the entire planet, what do you think the worldwide age of consent should be?

Keep in mind some factors as you think about your decision:

[list=1][*]At what age is a person sexually considered an adult?[*]At what age is a person mentally considered an adult?[*]How do geographic, economic and societal stresses and influences affect your decision?[*]Should an age of consent apply to age of marital conset as well? If it should, how should the age of marital consent be affected?[*]If a worldwide age of consent were reached, how should it legally be enforced? Should there be exceptions in cases of parental approval? Should there be an exception if both parties are under the legal age of consent?[*]Given technological advances and new science, are today's laws adequate to deal with underage sexuality? What could be done to further improve the laws governing age of consent?[*]Finally, in cases of underage sex leading to pregnancy, what should be the determined outcome of the fetus? Should all fetuses carried by illegally impregnated mothers be immediately terminated? Should the underage mother's parents decide what is best for the fetus? Should the underage mother be given a say in the matter? Whose responsibility should it be to raise the baby, if the fetus is allowed to go to term?[/list=1]

Never let it be said that we don't make you think around here.
