A few neighbourhoods in kathmandu hav been organising effective community clean-up efforts to keep trash off the streets, but out in the countryside there's no control, and everyone has someone else to blame.
The valley's ancient towns are afflicted with that plague of modern life,smog. The bowl-shaped valley is an ideal place for a thermal inversion. Dust particles and exhaust fumes combine with the winter mist to form murky haze. Thirty years ago the Himalayan peaks appeared crystal clear behind the valley rim to the north; nowadays they're frequently hidden behind the brown smudge. Public Enemy member one for environmentalists is the coal-burning Himal Cement Factory at chobhar, the valley's major industrial employer. In most of nepal, the air outside is clear. Pollution is hidden indoors, in poorly ventilated houses that trap smoke from cooking fires, causing eye infections and respiratory illnesses.Gravely pollutes water is a major carrier of disease. the valley's sewage treatment and water purification plants are rendered practically useless, as low water pressure and the close proximity of water and sewage pipes mean the water is dangerously fouled by the time it reaches home taps. chemical pollution is a growing danger in the valley, as industries pour untreated wastes directly into rivers, the traditional dumping ground for all kinds of garbage, despite their sacred status.
The most visible pollution appears on trails strewn with biscuit wrappers, noddle packages, and used toilet paper ,especially by tourists. Foreign visitors are the biggest sinners in this category because they can afford expensive packaged products,, but nepalis litter too. Until recently everything was either natural or recycled. Feasts were served on leaf plates and bags, old bits of metal were melted down into new cookpots. The advent of plastic has outpaced the realization that when you throw it away, it's there to stay.
