Environmental issues vary significantly across regions due to differences in geography, climate, economic development, population density, and resource use patterns. In South Asia, rapid population growth, urbanization, and industrialization have intensified problems such as air pollution, water scarcity, deforestation, and waste mismanagement. For instance, metropolitan cities experience severe air pollution due to vehicular emissions, coal-based power plants, and construction activities. In Sub-Saharan Africa, desertification, land degradation, and water stress are major concerns, often aggravated by climate variability and limited institutional capacity. Coastal regions worldwide, including small island developing states, face rising sea levels, coastal erosion, and increased frequency of extreme weather events due to climate change. In Latin America, large-scale deforestation in tropical forests contributes to biodiversity loss and increased carbon emissions. Industrialized regions such as North America and Europe
