Environmental health is intrinsically linked with sustainable development, highlighting the importance of balancing human progress with environmental preservation. Contemporary society's focus on technological and economic advancements often raises concerns about environmental deterioration, significantly impacting human health. This relationship is multifaceted, involving demographic factors, resource consumption, social and economic infrastructure, and environmental policies that influence the emission of pollutants and environmental degradation, ultimately affecting public health.

The connection between health and development is direct; insufficient development can lead to poverty, while overconsumption and rapid population growth may precipitate environmental hazards that jeopardize health outcomes in both developed and developing regions. Achieving improvements in community health necessitates a comprehensive approach integrating environmental, social, and economic sectors, involving interdisciplinary efforts across education, housing, public works, community organizations, and institutions. The World Health Organization (WHO) emphasizes that health is more than the absence of disease—it encompasses physical, mental, and social well-being (WHO, 1948).

Environmental definitions vary but are generally seen as dynamic systems comprising abiotic, biotic, and socio-economic elements that interact with humans (Law No. 81, Cuba, 1997). Human activities such as fossil fuel combustion, deforestation, and large-scale agriculture increase greenhouse gas concentrations, primarily carbon dioxide, methane, nitrous oxide, ozone, and CFCs, contributing to climate change. These alterations lead to direct health impacts—such as heatwaves and vector-borne diseases—and indirect effects, including food insecurity, altered vector distribution, and increased air pollution (McMichael et al., 1996).

Climate change presents complex health challenges, with increased risks from extreme weather events, degraded ecosystems, and pollution. Vulnerable populations, due to their lifestyle, occupation, or geographic location, face heightened risks. For instance, waterborne diseases proliferate in polluted water sources, disproportionately affecting children and marginalized communities. The social determinants of health—including education, income, and housing—modulate exposure to environmental hazards and influence health disparities (Yassi et al., 2000).

The concept of environmental health extends to addressing threats posed by rapid urbanization, industrialization, and resource depletion. The WHO classifies risks into "traditional risks," linked to poverty and inadequate sanitation, and "modern hazards," associated with development-related environmental hazards such as industrial pollution, radioactive contamination, and chemical exposure (WHO, 1992). In developing nations, traditional risks are prevalent, but the coexistence of modern hazards complicates public health responses, creating a transitional risk phase.

Strategies for mitigating environmental health risks include improving access to safe drinking water and sanitation, promoting sustainable urban planning, controlling pollution, and emphasizing community participation in health initiatives (PAHO, 2000). Implementing environmental health surveillance, developing health impact assessments, and quantifying disease burdens attributable to environmental factors are essential tools for policy formulation and targeted interventions. The DPSEEA framework (Driving forces, Pressures, State, Exposure, Effect, Action) provides a systematic approach to understanding and managing environmental health risks.

Interdisciplinary collaboration is critical. Environmental health problems are complex and demand integration across science, policy, and community engagement. The holistic, systems-based approach aligns with sustainable development principles, emphasizing safeguarding ecosystems, promoting social equity, and ensuring economic viability. Various global frameworks, including Agenda 21 and regional health and environment strategies, support such integrated efforts (UNEP, 1992; PAHO, 1999).

The assessment of environmental health impacts, through tools like the Environmental Burden of Disease, facilitates quantification and comparison of risks, enabling policymakers to prioritize interventions. Recognizing the vulnerability of specific populations guides targeted health promotion and protective measures. Ultimately, the pursuit of sustainable development requires a proactive stance: reducing exposures, enhancing resilience, and fostering environmentally healthy communities to achieve better health outcomes for present and future generations.

Environmental health is a vital component of sustainable development, emphasizing a balanced approach where human progress does not come at the expense of environmental integrity. This relationship underscores the necessity for policies and practices that safeguard natural resources while promoting health and well-being. The foundational premise is that environmental degradation—resulting from human activities—directly and indirectly influences health outcomes, making it imperative to integrate environmental considerations into development strategies.

Understanding what constitutes environmental health involves recognizing the complex interactions between abiotic components, biotic elements, and socio-economic factors that collectively impact human health. The environment is defined broadly as a system that interacts with human activities, transforming and meeting human needs through processes that sometimes lead to pollution and hazards. For example, fossil fuel combustion emits greenhouse gases such as CO2, CH4, and N2O, which contribute to climate change, thereby influencing health directly through heat stress and indirectly via altered disease patterns (McMichael et al., 1996). Rising temperatures and extreme weather events increase mortality and morbidity, especially among vulnerable populations.

The relationship between health and environment reveals disciplinary conflicts and challenges. While health professionals tend to focus on biomedical approaches, environmental issues often require ecological, engineering, and socio-economic perspectives. Effective management of environmental health risks involves overcoming this disciplinary divide through interdisciplinary collaboration. For instance, urban planning and architecture influence air quality, housing quality, and access to sanitation—all critical for health. Land-use policies and transportation planning can reduce pollution and promote physical activity, illustrating the importance of integrated approaches.

Sustainable development incorporates three pillars: economic growth, environmental protection, and social equity, all of which influence environmental health. The United Nations Conference on Environment and Development (UNCED, 1992) articulated that "human beings are the center of concerns for sustainable development" and that they are entitled to a healthy and productive life. This guiding principle emphasizes that health is both a goal and a prerequisite for development; healthier populations are more productive, and reducing environmental hazards reduces healthcare costs and social disparities.

Climate change represents one of the most significant contemporary threats to environmental health, driven primarily by anthropogenic greenhouse gas emissions resulting from deforestation, fossil fuel use, and industrial activity. The accumulation of gases like CO2 has led to global warming, with widespread health implications including increased heat stress, respiratory illnesses, vector-borne diseases, and food insecurity. For example, the expansion of vector habitats due to climate warming has led to the resurgence or emergence of diseases like malaria and dengue in regions previously unaffected (Yassi et al., 2000).

The health impact assessments and burden of disease studies developed by WHO and PAHO help quantify and visualize the extent of environmental risks. The Environmental Burden of Disease (EBD) methodology, for example, estimates the proportion of disease attributable to various environmental factors, guiding policymakers toward interventions that yield significant health benefits (Murray & Lopez, 1999). Such tools are complemented by frameworks like DPSEEA, which structure understanding of causal pathways from human activities to health effects. Their application enables targeted strategies for reducing exposures, such as improving sanitation infrastructure or regulating industrial emissions.

Addressing environmental health challenges requires community participation and intersectoral coordination. Educational campaigns, civic engagement, and policy reforms can foster environment-friendly behaviors and practices. In urban settings, sustainable planning that promotes green spaces, clean transportation, and adequate waste management can mitigate pollution and support physical and mental health. For example, promoting active transportation modes like walking and cycling reduces emissions, enhances physical activity, and improves overall well-being.

Policy frameworks such as Agenda 21 and regional health and environment strategies emphasize the importance of sustainable, participatory, and equitable approaches. Integrating health considerations into environmental policymaking ensures that development projects, infrastructure investments, and resource utilizations safeguard human health. International and regional cooperation, funding for research, capacity building, and technological innovation are crucial for implementing effective solutions at scale.

In conclusion, environmental health and sustainable development are deeply interconnected. Protecting the environment is essential for safeguarding human health, especially in the face of climate change, pollution, and resource depletion. Interdisciplinary approaches, robust assessment tools, participatory policies, and global cooperation form the pillars of effective action. Ultimately, achieving sustainable development goals depends on our collective capacity to harmonize human activities with environmental resilience, thereby ensuring a healthier future for all.
