One Child

I have heard some rumors throughout my life, and have now learned that some of them are true. I did not want to believe that in some parts of China, a woman can only have one Child. Has anyone thought about the fact that, one day the gender ratio will be off balance! That you will not have someone to carry on the family name, if you have only girls! I love children very much girls and boys. I would hate to have to choose between the two.
