World Population Sterilization

Well, my first point is a bit obvious. The human species can't continue if everyone is sterilized, so I'm going to assume you don't mean exactly everyone. If so who would determine the group of people not being sterilized? If a select group of people weren't sterilizing so they could produce the next generation to continue the species, the genetic diversity of the world would decrease dramatically. This means that future generations would more likely to become deformed and more prone to diseases and illness. Speaking in realistic terms an overwhelming majority of the human population would not agree with this extreme measure, but public opinion and politics aside it wouldn"t be logical to take such an extreme measure when the population naturally is going down in some parts of the world. Before 1600, the global average population growth rate was typically below 0.1 percent per year, meaning that the time it would have taken for the population to double was more than 700 years. Then, technology, health care, and sanitation improved, the growth rate increased. By 1965, the doubling time for the global population was 42 years. Since then, the global population growth rate has slowed down, and most likely to level off by 2100 without ever doubling again. Demographers needed to understand why the rate of the population growth fluctuated so much in the past and whether there were lessons to be learned from those fluctuations to help us understand the future, and through developing and testing the Theory of Demographic Transition was born. Historically, nations that have gone through similar processes of economic development have experienced similar patterns of population growth patterns. Scientists who studied the population growth patterns of European countries in the early 1900s described a four-phase process they referred to as the Demographic Transition. Now for a brief explanation of the Demographic Transition. The theory says that as the country moves from a subsistence economy to industrialization and increased affluence, it undergoes a predictable shift in population growth. At the beginning called phase 1 the country experiences slow or no growth. This phase is followed by rapid growth in phase 2. Many countries in Africa and some Asian countries, such as China and India are classified as being in phase 2. Countries such as the United States, Canada, and Australia are in phase 3, which is characterized by population stabilization. In phase 4, the population declines. Some western European nations are already in this phase like Germany. The population decreases when the birth rate is lower than the death rate, and it will not continue to decrease though. It will stabilize until the birth rate and death rate is the same. To stabilize it takes a couple generations and this can be viewed in age structure diagrams which display on a graph the percentage of females and males and their ages and depending on the country there will be three trends in the graphs. There could be a graph that has a bigger youth population which is mostly shown in developing countries like Venezuela and India this is also known as a population pyramid. Another graph is when it looks more like a column and this would be a kind of graph that Germany has. The third kind of graph looks like an upside triangle, and this means the population is decreasing, but a big shift generation to generation is bad for the economy, This is because the smaller population of youth would have to support a huge older generation who need social welfare programs to take care of themselves, and this is what started to happen when China put in place its one child policy.
