Theologian John S. Dunne tells the story about a group of Spanish sailors who reached the continent of South America after a long and dangerous voyage. They happened to approach right at the headwaters of the Amazon River, an expanse of water so wide the sailors assumed it was a continuation of the Atlantic Ocean.
The Amazon River is the greatest river in the world. It contains over 20% of the earth’s fresh water. During the rainy season it expands to 24.8 miles wide at inland points. Where it opens into the Atlantic Ocean it is 202 miles wide, discharging eight trillion gallons of fresh water a day into the ocean. That fresh water can be detected over 200 miles out into the sea.
