What country has polluted their water sources by tossing cremated remains into the river?

Answer:Congo River, Kinsuka

Explanation:The Congo River has a special place in the history of Congo - and to my own heart, as it is the river of my homeland. In fact the country is named after this huge river, the second largest freshwater river in the world, which covers 98% of DRC's surface area. Yet today, this remarkable natural lifeline is suffering not just from the threat of large dams to come, but also the modern scourge of pollution.
