The Soviet/Chinese/US liberal solution to unwanted pregnancies: abort every child possible so the sexual revolution may continue unencumbered by consequences. This is also the typical answer to any disease that comes from bad behavior. OK, maybe the Chinese and the Soviets were more acting pragmatic - but all these positions are coming from the Godless reactionaries just the same. There are two solutions to our population (family planning) and disease control problems worldwide, and they are solid unbreaking family relationships (you know, mother and father who love children - remember that?) and quality preventive medical services for married couples to plan children. There are social and moral issues to mold. The highest cause of unwanted preganancies in developed countries is unmarried sex. Unmarried sex is the largest cause of sexually transmitted disease in developing countries as well as developed countries (if you disagree, look up the definition of STD). Unmarried or promiscuous sex is bad.
The world's population will increase by 40 percent to 9.1 billion in 2050, but virtually all the growth will be in the developing world, especially in the 50 poorest countries, the U.N. Population Division said. - AP
And, what do we do about that? There's no question that exponential world population growth is a problem we need to address, mostly because the largest growth is coming from countries where people have a hard enough time supporting their children as it is. No unwanted children should ever be born. Science can help avoid unwanted children (before conception), if applied. And, the second and third world industrialize, the familial advantages of having more than one or two children greatly diminish.
