Who shares the world’s rivers? 313 basins, 19 countries on the Danube, and why nobody agrees on the longest river

313 river basins cross a border. They drain 47% of the world’s land outside Antarctica and hold 45% of its people. I mapped them, measured the great rivers on one map, and found the longest river depends on who holds the ruler.
