To celebrate the June 5 World Environment Day, diplomats from more than a dozen foreign embassies and international organizations Monday joined the U.S. State Department to plant underwater seagrass in the Potomac River, a tributary of the Chesapeake Bay. Diplomats told VOA their participation in “green diplomacy” is to help raise awareness of the challenges of clean water here and at home. By working with the CBF’s “Grasses for the Masses” program, diplomats are demonstrating the commitment to environmental protection.
