According to ForestEthics, more than 100 billion pieces of junk mail are delivered to U.S. households annually—more than eight hundred pieces per household—almost half of which 44 percent is thrown away before being opened.37 This consumes more than 100 million trees, equivalent to clear-cutting the entire Rocky Mountain National Park every four months.38
