U.S. Air Force Tech. Sgt. Darlene Rust, 633rd Force Support Squadron force management noncommissioned officer-in-charge, left, and Airman 1st Class Walter Johnson, 633rd FSS force management personnelist, clean the shoreline as part of Earth Week at Langley Air Force Base, Va., April 24, 2015. Langley Airmen also cleaned the area of debris and dead vegetation to restore the area, and make room for marsh grass, which prevents erosion on the shoreline preserving inland habits of the area.
