Filmed near Kathmandu (capital of Nepal). That plastic will flow to the Bagmati River -
In Kathmandu, the Bagmati River is destination of much untreated sewage, and large levels of pollution of the river exist due primarily to the region's large population. Many residents in Kathmandu empty personal garbage and waste into the river. In particular the Hanumante khola, Dhobi khola, Tukucha khola and Bishnumati khola are the most polluted. Attempts are being made to monitor the Bagmati River system and restore its cleanliness. These include "pollution loads modification, flow augmentation and placement of weirs at critical locations". The "Friends of the Bagmati" is an organisation set up in November 2000. According to its website, its aim is, "to reverse the degradation of the Bagmati river."- and eventually I presume to the Bay of Bengal and the Indian Ocean.
