1. Summary
Demography is a study of population dynamics. It includes research on the size, structure and distribution of the population and how the population changes over time due to birth, death, migration and aging. The reason for studying demography can be found in sociology. Sociology must transform into a statistical indicator when describing social phenomena, and demographic analysis helps to make many sociological explanations. Demography, a modern census, began in the late 18th century.
Demographic statistics mainly involve long-term and large-scale surveys. Because demography is literally interested in human population changes, it also focuses on specific indicators of change. Fertility and mortality are good examples of these specific indicators.
Population overruns represent scenarios in which populations of living species exceed the capacity of ecological niche. The world's population is growing by 80 million every year, with most births taking place in Africa, especially in developing countries. In the early 19th century, Thomas Malthus argued that population should be controlled because the population is growing exponentially but food is slowly increasing. Over time, however, food production has grown faster than population growth. However, overpopulation can shorten the life expectancy, cause fewer surplus foods, insufficient arable land, pollution, and so on. In order to overcome this overpopulation, there are ways of survival of the fittest and ways of reducing the birth rate through economic development.
Urbanization is the physical growth of urban areas. It happens mainly in developing countries, and it becomes more prominent as people migrate to cities to get economic opportunities. This causes positive and negative economic effects as well as environmental effects.
2. Interesting point
I thought urbanization would have only a negative impact on the environment, such as environmental pollution. But it is interesting to note that the impact of urbanization can have a positive impact on the environment as a whole. This article's view of discontinuing destructive livelihoods and minimizing land use by humans shows a different perspective than before.
3. Discussion Point
Historically, the world population has grown modestly since it has been a hotbed and a plague in 1350. In 2017, the population is 7,491 million. In fact, if food problems are met, the population will be able to cope no matter how much. But some people think that population growth will be faster than the development of such technology. What do you think?
