The Environmental Performance Index lists countries based on how well they protect human health and natural ecosystems. This rating system uses numerous indicators to measure critical issues like air quality, waste management, and the protection of wildlife habitats.

Many of these regions face heavy air pollution from burning wood for daily fuel or from unregulated factory exhaust, while others deal with rapid loss of forest land and failing trash disposal systems.
