First off; it is not, as advertised the only movie on population. It may be one of the few to discuss the connection between the empowerment of women leading to fewer children. As far as it went, it was an excellent film and I showed it legally to our local Sierra Club group. It was well received by all and I felt it was well made and made many good points. The only fault I had with the film was that while it was breaking one 'taboo', it was avoiding or ignoring an even stronger, more scary subject; that role which organized religion plays in controlling population. We will have to wait for that watershed moment and in the USA, the requirement for announcing your religious beliefs has become almost pandemic to the point where any politician not talking about their religion is akin to failing to praise the troops or not wearing a American flag lapel pin. There are many ways that population levels can start being reduced, but first people can't be afraid to talk about it. Without that next step being taken, very little progress can be made.
