Agriculture is the critical juncture in the history of humans. About 11,000 years ago, people changed from hunting life to food producers by agriculture. It changed their lifestyle and had more time to learn and gain knowledge by studying the life that surrounds them. They settled down in life by farming. For decades, people started to cultivate a new type of crop and used animals by experimenting in their own land, which is enough to feed their families. About 1960, high-yield production of wheat and rice were developed by researchers emerged as the green revolution. Food production plays an important role in population growth and change in politics. Shortage of food arises due to uneven distribution of resources and overpopulation. The challenges in feeding the hungry depend on the type of land and water, which is overcome by agricultural science.
The Rise of the Smart City

We do not consider that these statistics are very comforting or static, while the population of the world is ballooning by 80 million per year. Overpopulation is an undesirable condition where the existing human population exceeds the carrying capacity of Earth. Overpopulation is caused by a number of factors: reduced mortality rate, better medical facilities, preventive medicine, more support to overcome poverty, lack of family planning, and the depletion of precious resources. Conflicts over water are becoming a source of tension between countries, which could result in wars. Such conflicts cause more diseases to spread and make them harder to control. Starvation is a huge issue facing the world and the mortality rate for children is being fueled by it. Poverty is the biggest hallmark when we talk about overpopulation. Let’s not forget global warming and Arctic melting and how these directly impact the habitat of human beings. The Arctic sea ice could potentially harm human beings by reducing certain animal habitats that are used for subsistence.
Population Policies and Dilemmas
Published in Gregory T. Haugan, The New Triple Constraints for Sustainable Projects, Programs, and Portfolios, 2016
Overlay: There are two parts to population policies One is limiting the total population due to the limited resources available for support. The other part of the equation is economic growth. The primary problem that needs solving is poverty, not overpopulation. The most effective population control mechanism is the most simple and is female education, which is occurring even in the most densely populated and repressive countries Raising incomes is the key With a stable total population and a continuing rise in GDP, the standards of living for the world's population would be increasing Program planners should support and encourage programs that raise GDP and at the same time support and encourage education of women. The economic environment of programs in the coming decades will depend upon these two factors: population growth and per capita GDP growth.

Human life severely depends on the quality of water as an essential hot spot to provide the worldwide population demand. The water demand has increased for anthropogenic activities due to overpopulation. Approximately 844 million people have no access to safe drinking water and 1.6 million people die annually from waterborne disease regarding the world health organization (WHO) reports [1,2]. Therefore, water scarcity and less accessibility of freshwater have been a serious challenge due to industrialization and urbanization in the last decade. Multiple contaminants such as toxic metals, organic matter, pesticides, and dyes have compromised the water resources. Among them, heavy metals and organic pollutants are responsible for the high incidence of poisoning in humans, even at low levels [3].
Does Health Promotion Harm the Environment?

The tension between human and environmental health, then, is a consequence of overpopulation. This is not yet a problem of raw numbers of people on the planet, but of some number of people using resources at some particular level. Climate change is caused by some number of people emitting at various levels. If we are unable to successfully decrease their emissions fast enough to prevent massive harm to the environment, and then to humans, there is another variable to which we could apply pressure: the number of emitters. That is to say: both human and environmental health could be promoted by reducing the number of people on the planet.

Meanwhile, humanity faces the problem of increasing levels of environmental pollution, which is directly linked to global warming (Masson-Delmotte et al., 2018). The world also deals with food insecurity caused by overpopulation, the lack of agricultural land, and the expectation of increased immigration to cities. The number of residents residing in urban areas is expected to increase (Teo & Go, 2021; United Nations, 2018). With the spread of COVID-19, the problem of food insecurity has multiplied because of suspended production and increased demand for food storage during the periods of closure (The World Bank, 2022).
