The Human Population

The situation in developing countries is completely different from the situation in developed countries. Fertility rates in developing countries are generally declining, but they still exceed the alternative levels (Wright 2005). When the number of births reaches the number of deceased people population increase will occur. Under this momentum of population growth, developing countries will achieve tremendous growth even after the total fertility rate has fallen to alternative levels (Wright, 2005). In developed countries like the United States, advanced population statistics will increase and decrease accordingly, which seems to be different (Wright 2005).

Demographics is to intentionally manage population growth rate. Historically, population planning has been implemented to increase the population growth rate. However, from the 1950s to the 1980s, efforts were made to lower the population growth rate due to concerns about the world's population growth and its impact on poverty, environmental deterioration, and political stability. Recently, in some countries such as Iran and Spain, we are working hard again to raise the birthrate.

Population planning is to artificially change population growth rate. Historically, demographics have been implemented by limiting the birthrate of the population, usually in response to governmental orders, and to factors such as the height and increase of poverty, environmental problems, religious causes, over-population, etc. . . Population planning can include measures to improve people's lives by giving people better control over their reproductive but some programs have exposed them to exploitation.

The annual population growth rate doubles every ten years. In 2000, the world's population exceeded 6 billion people. As of 2014, the population has increased by more than 7 billion people. People live in different areas and are scattered a little, but there are areas where the population is densely populated. For this reason, in many countries, especially countries that are delayed in development, we prioritize men over women. Finally, in most societies, unintended pregnancy leads to overpopulation because of lack of understanding of sexual relations and birth control. Therefore, overpopulation will have many adverse effects. The vast majority of today's important environmental problems are the result of excessive consumption caused by overpopulation.
