| Environment - current issues | rapid population growth pressuring the environment; overharvesting of timber, expansion of cattle grazing, and slash-and-burn agriculture have resulted in deforestation, soil exhaustion, and flooding; loss of biodiversity; air pollution; water pollution; overfishing | deforestation; inadequate potable water; desertification; soil contamination and erosion; overfishing, overpopulation in forest region; poor mining practices lead to environmental damage; water pollution; improper waste disposal |
