KINDERDIJK, The Netherlands -- It’s a tourist thing, these windmills. The windmill keeper wears wooden shoes. They are made of the simplest materials. Bricks, wood, straw on top.

The Amazon is the world's second longest river. It stretches east-west across South America. The river's watershed drains an area nearly 3 million square miles wide and accounts for approximately twenty percent of the world's total flowing water. Now Brazilian researchers report finding a ...
