Larger numbers of women and perhaps gay men will reduce the incidence of violence in their communities. I also see a business opportunity. Marriage tourism. Internet sites and planeloads full of men from places like China and India, where female children are undervalued, should be easy to monetize. Its like global warming. In Saskatchewan we see nothing but upside.
Don't forget that Phthalates also increase your chances of being gay. Apparently in some South American countries the number of gay men is starting to mess with the census numbers.
