Time to re-write those geography books

Geography books around the world state the Nile in Egypt as the longest river in the world, and the mighty Amazon as only second to it. The river, though, is recognised as the world’s largest by volume, with a flow greater than that of the eight largest rivers combined.

Now, a new research in Brazil claims to have established as a scientific fact that the Amazon is the longest river in the world. Researchers have established a new starting point further south in the Peruvian Andes, which effectively puts the river’s length at 6,800 km (4,250 miles) compared to the Nile's 6,695 km.

The river, according to the team of scientists, who followed a 14-day expedition, sometimes in freezing temperatures, to trace its source, is said to begin in an ice-covered mountain at an altitude of 5,000 metres in southern Peru called Mismi.

Guido Gelli, director of science at the Brazilian Institute of Geography and Statistics, told the Brazilian network TV Globo that on Tuesday, it could already be considered as a fact that the Amazon was the longest river in the world.

The expedition was co-ordinated by the National Geographical Institute of Peru, reports the BBC.
