Hindu pilgrims on overloaded river boat on the Ganges river, in Varanasi (India).
Most Indian people cannot swim, so if a boat like this were to capsize or sink, it would kill many people (as there are no life-vests on those small river boats, of course).
Those boats are used for ferrying the Hindu pilgrims to a beach across the Ganges river, where they can take the Holy bath in cleaner water.
