If Amazonia were a country, it would be the ninth largest in the world. The Amazon rainforest, the world's greatest remaining natural resource, is the most powerful and bioactively diverse natural phenomenon on the planet. It has been described as the "lungs of our planet" because it provides the essential service of continuously recycling carbon dioxide into oxygen. It is estimated that more than 20 percent of Earth's oxygen is produced in this area.

The Amazon covers more than 1.2 billion acres, representing two-fifths of the enormous South American continent, and is found in nine South American countries: Brazil, Colombia, Peru, Venezuela, Ecuador, Bolivia, Guyana, French Guiana, and Suriname. With 2.5 million square miles of rainforest, the Amazon rainforest represents 54 percent of the total rainforests left on Earth.

The Amazon River

The life force of the Amazon rainforest is the mighty Amazon River. It starts as a trickle high in the snow-capped AndesMountains and flows more than 4,000 miles across the South American continent until it enters the Atlantic Ocean at Belem, Brazil, where it is 200 to 300 miles across, depending on the season. Even 1,000 miles inland it is still 7 miles wide. The river is so deep that ocean liners can travel up its length to 2,300 miles inland. The Amazon River flows through the center of the rainforest and is fed by 1,100 tributaries, 17 of which are more than 1,000 miles long. The Amazon is by far the largest watershed and largest river system in the world occupying over 6 million square kilometers. Over two-thirds of all the fresh water found on Earth is in the AmazonBasin's rivers, streams, and tributaries.

With so much water it's not unusual that the main mode of transportation throughout the area is by boat. The smallest and most common boats used today are still made out of hollowed tree trunks, whether they are powered by outboard motors or more often by human-powered paddles. Almost 14,000 miles of Amazon waterway are navigable, and several million miles through swamps and forests are penetrable by canoe. The enormous Amazon River carries massive amounts of silt from runoff from the rainforest floor. Massive amounts of silt deposited at the mouth of the Amazon River has created the largest river island in the world-Marajo Island, which is roughly the size of Switzerland. With this massive freshwater system, it is not unusual that life beneath the water is as abundant and diverse as the surrounding rainforest's plant and animal species. More than 2,000 species of fish have been identified in the AmazonBasin - more species than in the entire Atlantic Ocean.
