A recent study is indicating that the recent drought in Brazil may be the result of years of unchecked deforestation. It appears that trees in the Amazon jungle do more than remove carbon from the air. Trees also draw water from the ground and add moisture to the air. It is estimated that two-thirds of the rainfall in southeaster Brazil can be attributed to moisture released by trees into the air. Trees pump about 20 billion metric tons of water into the atmosphere every day, about 3 billion tons more than the Amazon river dumps into the ocean.
