The US Census Bureau reports that there are nearly seven billion people in the world
The US Census Bureau reports that there are nearly seven billion people in the world (US Census Bureau, 2011). The increase in population size over recent decades has created, and will continue to create, environmental and public health concerns. A larger population consumes already limited resources and energy and creates more waste and pollution. A larger population also exacerbates public health issues. For example, a boost in population size can lead to an increase in rates of infectious disease, homelessness, and poverty.
Currently, different parts of the world have varying population growth rates. Population growth in more developed countries is slowing down. For example, between 2005 and 2010, women from North America had an average of only two children in their lifetime. However, population growth rates in developing countries are still quite high. Specifically, between 2005 and 2010, women from Africa had an average of 4.6 children in their lifetime (United Nations: Department of Economic and Social Affairs, Population Division, 2007).
In this assignment, you will estimate the future population sizes and their potential link to environmental health. Using the readings for this module, Argosy University online library resources, as well as resources from reliable academic or governmental organizations, write a paper that addresses the following: Estimate the predicted population size for the world in the year 2060. Be sure to justify your estimate as well as cite and explain the resources you used. Identify a single disease that significantly increases in prevalence when the human population increases in size. Address the following based on this information: Why is this issue likely to increase with an increasing population size? Are there any countries in particular that will be affected by this issue more than others? What will cause this discrepancy? How are food supply and nutrition impacted by the increasing population size? When considering nutrition, do you think some countries will be more susceptible than others? Explain and support your answer. What are governmental agencies currently doing to prevent or mitigate concerns of inadequate food supply and nutrition because of population growth? Based on your research, do you believe that these policies would change if the population growth increases dramatically by 2060? Support your statements with scholarly references and appropriate examples. Write a 2–3-page paper in Word format. Apply APA standards to citation of sources.

The ongoing concerns about global population growth and its impact on environmental and public health are pressing issues that warrant comprehensive analysis and strategic planning. By 2060, the world population is projected to reach approximately 9.7 billion people, according to United Nations (2019) estimates. This projection accounts for current growth trends and demographic changes observed across different regions. Justification for this estimate stems from demographic models that incorporate fertility rates, mortality rates, and migration patterns. The United Nations Department of Economic and Social Affairs (2019) utilizes these parameters to forecast population trajectories, indicating a steady but decelerating growth rate in some regions, contrasted with higher growth in others, particularly in Africa. Such projections highlight the demographic shifts that will influence resource consumption, disease prevalence, and nutritional status globally.
One significant disease that is likely to increase with population size is infectious and parasitic diseases, such as tuberculosis (TB). As populations grow, especially in densely populated and underserved regions, the transmission rates of communicable diseases tend to rise due to increased contact rates, overcrowding, and inadequate sanitation (World Health Organization [WHO], 2021). Larger populations result in higher disease burden because health infrastructure becomes strained, making disease prevention and treatment more challenging. Developing countries, particularly in Africa and parts of Asia, are more susceptible to this issue because of existing limitations in health systems, sanitation, and access to healthcare resources. The discrepancy arises from socioeconomic disparities, urbanization rates, and governmental investment in healthcare (Smith & Jones, 2020).
Food supply and nutrition are critically impacted by the increasing global population. As the number of people rises, the demand for agricultural produce intensifies, leading to overexploitation of arable land, water resources, and biodiversity. Some regions, especially in Sub-Saharan Africa and parts of South Asia, will be more susceptible to food insecurity due to limited agricultural infrastructure, climate change impacts, and economic constraints (FAO, 2020). Countries with higher poverty levels and weaker food distribution systems face greater risks of malnutrition, micronutrient deficiencies, and famine. Nutritional disparities are accentuated by socioeconomic inequalities, which influence access to diverse diets, clean water, and healthcare services. This heterogeneity in susceptibility underscores the need for targeted interventions and sustainable agricultural practices (FAO, 2020).
Currently, governmental agencies like the Food and Agriculture Organization (FAO), World Health Organization (WHO), and national governments are implementing policies and programs to address
concerns about food security and nutritional adequacy. Initiatives include promoting sustainable farming practices, enhancing food distribution networks, fortifying staple foods with micronutrients, and improving water and sanitation infrastructure (FAO, 2021; WHO, 2021). Additionally, investments in research, education, and technology aim to increase crop yields and resilience against climate change effects. However, if population growth accelerates significantly by 2060, these policies may require substantial revision or expansion. For instance, more aggressive strategies such as large-scale agricultural innovation, biotechnology, and international cooperation may become necessary to meet the surging demand. Policymakers will need to adapt to demographic shifts to prevent future crises related to food insecurity and malnutrition (Godfray et al., 2010).
In conclusion, the projection of a near 10-billion population by 2060 underscores the urgency of implementing proactive measures to manage environmental and public health challenges. The anticipated rise in infectious diseases, food insecurity, and nutritional disparities will necessitate innovative policies, international collaboration, and sustainable practices to ensure a healthy and resilient global community. Continued research and strategic planning are essential to address these complex issues effectively and equitably.
