While I completely share your fears about the overpopulation issue and, you are completely right about it, except that we´ll never reach a 100 billion people mark, but, probably will die trying, since nothing is being done to slow population growth, at least not at government level.

I cannot, actually accept that one could consider AIDS to be a valuable asset in fighting overpopulation, one, it´s very cruel and 2, but far more important, it´s completely inefective, the countries with the most occurence of it are also the ones with higher fertility rate.

Also, about your approach on sex and reproduction, while almost all of the reproductions happen because of a sexual relationship, a very small fraction of every sexual intercourses actually end in pregnancies, so, there´s not a correlation on how much sex a person can have and how many offsprings they produce, actually childless people use to have far more sex than parents.

Continuing, we are going to overpopulate this planet with or without aids, so a better solution must be found…

Anyway, I´m glad to know there´s more people worried about it.

thanks and please accept my apologies for my poor english
