This picture speaks volumes.
…the Citarum is a river in crisis, choked by the domestic waste of nine million people and thick with the cast-off from hundreds of factories. So dense is the carpet of refuse that the tiny wooden fishing craft which float through it are the only clue to the presence of water.
Its demise began with rapid industrialisation during the late 1980s. The mighty Citarum soon became a garbage bin for the factories.
And the doomsday effect will spread. It is one of two major rivers that feed Lake Saguling, where the French have built the largest power generator in West Java.
Experts predict that as the river chokes, its volume will decrease and the generator will not function properly.
The area will be plunged into darkness.
But at least the factories will be stilled and their waste will stop flowing.
And perhaps the river will begin to breathe again.
