The Tree That Waters Itself For 50 Years- Why Did America Cut Down 3 Billion of Them? The American Chestnut once dominated the Eastern United States. Four billion trees. Two hundred million acres. One in every four hardwoods from Maine to Georgia. Then we cut down 3 billion of them in 40 years. This tree could pump water from 100 feet underground and release it into the topsoil at night—irrigating entire ecosystems without a single drop of rain. One tree produced 300 pounds of protein-rich food every fall. The wood lasted centuries. Termites wouldn't touch it. The Cherokee called it the bread tree. Colonial families survived winters on nothing else. The Appalachian economy ran on it. Then a fungus arrived in 1904. And the logging industry saw an opportunity. What happened next wasn't a tragedy. It was a liquidation sale.
