This insight explores how environmental factors such as air quality, water quality, waste management, and green spaces influence public health outcomes. The model illustrates the relationships between pollution, disease prevalence, healthcare demand, and community well-being. It is intended as an educational systems-thinking example that helps users understand how improvements in environmental management can contribute to healthier populations and more sustainable healthcare systems. The model can be expanded to test different policy scenarios and evaluate their long-term effects on environmental and health indicators.
