This unpleasant image is a summation of what happens when spiritualism meets industrialism. The water you can see is that of the River Ganges. It's one of the most famous rivers in all the world, flowing through India, and of particular importance to those of the Hindu religion. It's also very heavily polluted.
Because of poorly developed waste disposal methods, both industrial and human waste flows out into the Ganges. However, for both spiritual and practical reasons, people still bathe and wash their clothes in the water of the Ganges, despite what their eyes and nose can clearly tell them about the quality of the water they're wading into, and what's in it. That's the stage we've now reached with industrialization; people bathing in human waste. With a little more care, and investment in education, we could stop this.
