Human Population And Toxins Resource: Different Persp 135929

Human Population And Toxins Resourcethere Are Different Perspectives O

There are different perspectives on human population growth and the dynamics associated with population change. Go to CIA World Factbook website and choose one developed (not the United States) and one developing country and compare the following and answer the questions: Developed country (Developed country is a country which has an effective rate of industrialization and individual income) Developing country (Developing country is a country which has slow rate of industrialization and low per capita income) Population growth rate Birth rate Death rate Net migration rate Each question should be answered in a minimum of 200 words.

1. Why do you think the population is increasing or decreasing for that country? Try to explain at least two reasons as to why this is happening? (Please refer to your textbook)

2. How do diseases affect the population? Can you think about any diseases that has affected the human population? (Please use peer reviewed sources to support your answer).

3. Looking at the countries you compared, what are the toxins present in the environment that impact human health? Provide one example for each country.

Paper For Above instruction

For this analysis, I selected Japan as the developed country and Nigeria as the developing country, utilizing data from the CIA World Factbook to compare their demographic and environmental health indicators. The contrasting population dynamics and environmental toxin exposures in these nations underscore the complexities of public health in different developmental contexts.

1. Population Trends: Reasons for Increase or Decrease

Japan’s population has been experiencing a decline over recent decades, primarily attributable to its low birth rate and high aging population. The declining birth rate in Japan can be linked to cultural shifts, increased participation of women in the workforce, economic uncertainties, and lifestyle choices that favor smaller families (United Nations, 2019). Additionally, high costs of child-rearing and limited work-life balance contribute to reduced fertility rates. The aging population results in higher mortality rates among the elderly, with fewer younger individuals replacing the aging cohort, leading to population decline (Kaneko, 2020). Conversely, Nigeria exhibits a rapidly increasing population characterized by high birth rates and significant net migration. Nigeria’s high fertility rate is driven by cultural preferences for larger families, limited access to family planning services, and socio-economic factors that value early marriage and higher fertility (World Bank, 2022). Despite some urbanization, many rural areas maintain traditional demographic patterns, supporting population growth. Migration trends in Nigeria are also characterized by internal rural-to-urban movements, contributing to demographic shifts but still maintaining overall high growth rates (United Nations, 2019). Therefore, economic, cultural, and social factors are primary drivers behind these differing population trajectories.

2. Impact of Diseases on Population

Diseases significantly influence population size and structure by affecting mortality and morbidity rates. Pandemics like COVID-19 have demonstrated the profound impact of infectious diseases on global populations, causing millions of deaths and overwhelming healthcare systems (World Health Organization, 2022). Historically, diseases such as malaria have substantially affected population dynamics, particularly in tropical regions like Nigeria, where endemic malaria has contributed to high mortality rates, especially among children and pregnant women (Njuk, 2020). Malaria not only increases death rates but also impacts economic productivity and healthcare costs, ultimately shaping population growth patterns. In developed countries like Japan, chronic diseases such as cardiovascular diseases and cancers are leading causes of death, driven by lifestyle factors and aging populations. These diseases tend to increase the burden of mortality among elderly populations but have less impact on overall population decline compared to infectious diseases in developing nations. Peer-reviewed research emphasizes how infectious diseases can reduce population sizes abruptly or gradually, depending on intervention effectiveness, healthcare infrastructure, and disease virulence (Murray & Lopez, 2019). Thus, managing infectious diseases remains pivotal in shaping demographic trends worldwide.

3. Environmental Toxins and Human Health

Environmental toxins significantly influence public health outcomes by contributing to chronic and acute diseases. In Japan, a notable toxin is mercury, which was historically prevalent due to industrial activities and the use of mercury in fisheries and manufacturing processes. Mercury bioaccumulation in fish has led to concerns about neurological health, especially in populations with high seafood consumption (Yorifuji et al., 2017). In Nigeria, lead exposure is a prominent environmental toxin, largely resulting from informal e-waste recycling activities and artisanal mining. Lead poisoning has been linked to developmental delays in children and neurological impairments (Akinlabi et al., 2018). Both toxins exemplify how industrial and informal sector activities in different contexts create environmental health challenges. Recognizing these toxins’ impacts underscores the importance of environmental regulation and public health initiatives aimed at reducing exposure and mitigating adverse health outcomes in both developed and developing nations (WHO, 2020).
