Environment - current issues:
lack of important arterial rivers or lakes requires extensive water conservation and control measures; growth in water usage outpacing supply; pollution of rivers from agricultural runoff and urban discharge; air pollution resulting in acid rain; deforestation; soil erosion; land degradation; desertification; solid waste pollution; disruption of fragile ecosystem has resulted in significant floral extinctions
