India's Effort To Clean Up Sacred But Polluted Ganga River

The Ganga River, known as the Ganges under British rule, is one of the most
revered waterways in the world -- and also among the most polluted.
Stretching from the Himalayan foothills to the Bay of Bengal, it provides
water to nearly half a billion people, more than any other river in the
world. Special correspondent Fred de Sam Lazaro reports from India on the
latest efforts to clean the river.
