You're looking at the Citarum river, near the Indonesian capital of Jakarta, which is probably the world's most polluted river:
More than 500 factories, many of them producing textiles which require chemical treatment, line the banks of the 200-mile river, the largest waterway in West Java, spewing waste into the water.
On top of the chemicals go all the other kinds of human detritus from the factories and the people who work there.
There is no such luxury as a rubbish collection service here. Nor are there any modern toilet facilities. Everything goes into the river.
The filthy water is sucked into the rice paddies, while families risk their health by collecting it for drinking, cooking and washing.
