Answer The Following Questions To Complete Homework 3 Necessary Libra answer the following questions to complete Homework 3. Necessary library and Internet research are needed to answer these questions. Make sure your answers meet course requirements: What are the leading risk factors that contribute to death and disability in low- and middle-income countries, and how do they differ from those found in high-income countries? Given current trends in risk factors, what re likely to be the major cause of death and disability in low- and middle-income countries in the 2020s and beyond? Which policies and actions taken over the next decade at national and international levels could influence these trends, and which factors might facilitate their implementation. What are the characteristics of particular environmental health problems that render them more, or less, tractable to amelioration or elimination? As the scale of human impact on the global "environment" increase, people become more concerned about the consequences of disruption of our "habitat." What does this signify?

Understanding the primary risk factors contributing to death and disability across different income groups provides vital insights into global health challenges. In low- and middle-income countries (LMICs), leading risk factors often include infectious diseases, maternal and child health issues, malnutrition, and exposure to environmental hazards such as unsafe water and air pollution. These regions face a higher burden of communicable diseases like tuberculosis, HIV/AIDS, and malaria, which significantly impact mortality and morbidity rates (World Health Organization [WHO], 2021). Conversely, high-income countries (HICs) tend to see non-communicable diseases (NCDs) such as cardiovascular diseases, cancers, and chronic respiratory conditions as the predominant causes of death and disability (Burgess et al., 2020). The epidemiological transition reflects socioeconomic development, healthcare infrastructure, and lifestyle factors, which influence the distribution of risk factors globally (Marmot, 2015).

Looking ahead to the 2020s and beyond, projections suggest that NCDs will increasingly dominate health burdens in LMICs, fueled by urbanization, aging populations, and lifestyle changes, including sedentary behaviors and unhealthy diets (Ng et al., 2014). Moreover, infectious diseases might persist as significant threats, particularly antimicrobial resistance escalates and climate change exacerbates health vulnerabilities (Gilder et al., 2021). The major causes of death and disability are likely to be cardiovascular diseases and cancers, with mental health conditions gaining recognition as critical components of global health concerns. Addressing these emerging trends requires coordinated policies—such as strengthening healthcare systems, promoting health education, implementing prevention programs, and expanding access to essential medicines. International cooperation can facilitate technology transfer, capacity building, and funding, all of which are vital for effective intervention (Katz et al., 2018).

Environmental health problems' characteristics—such as their scale, complexity, and the socioeconomic context—determine their tractability. Problems like air and water pollution are more manageable through regulatory measures, technological innovations, and behavioral change. For instance, technological advances in clean energy and pollution control are effective tools to tackle environmental degradation. Conversely, issues rooted in deep-seated economic and social disparities, such as climate change, pose more formidable challenges due to their systemic nature and global scope (Landrigan et al., 2018). As human impact on the environment intensifies, concerns about habitat disruption amplify, reflecting recognition that ecological stability is fundamental to human health and well-being. This signifies a paradigm shift towards sustainable development models that integrate environmental preservation with economic and social equity. It underscores the necessity for comprehensive policies that address environmental determinants of health, promote resilience, and ensure sustainable use of resources to safeguard future generations (Rockström et al., 2017).

In conclusion, addressing global health disparities and environmental issues necessitates a multifaceted approach encompassing policy reforms, technological innovation, international collaboration, and community engagement. Recognizing the interconnectedness of health and environment underscores our collective responsibility to foster sustainable ecosystems that support human health in an increasingly interconnected world (Sachs, 2015). Strategic actions now will shape the trajectory of health outcomes and environmental stability for decades to come, emphasizing the urgency of integrated solutions at all levels of governance.
