Philip proposes that we should modify the entire human race for them to have fewer possibilities to reproduce as a measure of birth control. As a prerequisite you will need to modify every single newborn, if we had the resources to influence how every single new person is born, we would actually be at the point where we could stop thos non desired borns in a much simpler way...
Anyway, there's an easier way that actually has many other upsides. Philip, let's solve poverty instead of proposing sci-fi :-)
