Yesterday was the Jewish holiday of
Tu Bishvat, a minor holiday also known as the "New Year of the trees."
Haaretz reports that to commemorate the day, the U.S. Department of Agriculture Under-Secretary who oversees the U.S. Forest Service, Harris Sherman, planted a redwood tree in a ceremony held near USDA headquarters in Washington. Other Obama officials this week planted trees in Arizona, Colorado and Israel to mark the holiday.
