| Summary: | Long-term exposure to ambient fine particulate matter (PM2.5) air pollution presents a marked environmental risk factor affecting human health and has been demonstrated to increase human morbidity and mortality rates. In contrast to the health risks posed by air pollution, a healthy ecology serves as the foundation for human survival and well-being. However, there are still issues of ecological distribution and possession that are inequitable between humans and nature, as well as between different countries. This study scrutinizes the global, national, and grid-scale disparities in PM2.5 exposure and ecological possession during the period 2001–2020. Our findings reveal that (a) PM2.5 concentrations have been on the rise in several countries, including India, Saudi Arabia, Yemen, Russia, Turkey, Bangladesh, Ethiopia, Algeria, Iran, and Myanmar. Conversely, a decreasing trend in PM2.5 levels is evident in China, the United States, Brazil, Canada, and most European countries. (b) A notable decrease in the risk of PM2.5 exposure has been observed in densely populated regions in south-eastern China, specifically along the Heihe–Tengchong Line, attributable to a series of effective management measures. (c) Lower ecological quality possession was observed in parts of the Americas, Africa, Asia, and Europe, suggesting increased competition for ecological resources in these regions. We emphasize that humanity shares a common destiny within the global community, and strongly advocate for governments and relevant bodies to address these disparities in PM2.5 exposure and ecological quality possession, with the aim of preserving the environment and attaining sustainable development goals. |
