The Amazon rainforest forms a pulsating network of water and trees: every year, its canopy receives between 1,500 mm and 3,000 mm of rainfall.

Eastern trade winds that blow from the Atlantic Ocean account for about half of the rainfall, with the other half due to evapotranspiration - the loss of water from the soil by evaporation and through transpiration from plants - in the Amazon River Basin.

Together with an average temperature of around 24 °C or more, the constant water cycle not only creates the typical humid and warm atmosphere of a tropical rainforest, but more importantly regulates local and regional climates.

If evapotranspiration and its role in maintaining ecological balance is disrupted, the climate throughout the region - and well beyond - will be significantly affected.
