The Human Population: Eco-City Planning

As of October 31, 2011, the population of the world has reached 7 billion (Collins, 2012). Human growth rates are still phenomenal, which creates the need for land use, resource allocation, and more importantly to achieve the environmental pressures associated with further development (Ascione, 2009). The rapid growth of human development in recent years has raised awareness of natural ecosystems (Savard & Clergeau, 2000). This environmental awareness creates an environmental plan.

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.

In the 1980s, as part of a human rights-based approach, the tension between population planners and women's health activists promoting female reproductive rights increased. More and more people are opposed to a narrow population plan, which brought about a major change in the policy of demographic planning in the early 1990s. Economists have a variety of views on the impact of demographic changes on national economic health. In the 2009 scientific research in the US, parenting costs about $ 16,000 per year annually (the total cost to bring up a child by the age of 18 years old is $ 291,570). In the United States, this figure multiplied by the annual population increase is the overall cost of population growth. Costs of other developed countries are usually on the same scale.
