The River Basin at the center of Latin America called the Amazon is roughly the size of Australia. Created at the beginning of the world by a smashing of tectonic plates, it was the cradle of inland seas and continental lakes. For the last several million years, it has been blanketed by a teeming tropical biome of 400 billion trees and vegetation so dense and heavy with water, it exhales a fifth of Earth’s oxygen, stores centuries of carbon, and deflects and consumes an unknown but significant amount of solar heat. Twenty percent of the world’s fresh water cycles through its rivers, plants, soils, and air. This moisture fuels and regulates multiple planet-scale systems, including the production of “rivers in the air” by evapotranspiration, a ceaseless churning flux in which the forest breathes its water into great hemispheric conveyer belts that carry it as far as the breadbaskets of Argentina and the American Midwest, where it is released as rain.
