Celebrating Earth Day ? Coast to Coast

April 22, 2014 by NOAA Marine Debris Program

By: Asma Mahdi

Earth Day celebrations are in full-swing today, and this Earth Month
volunteers have been diving deep into tons, literally tons, of spring
cleaning for our planet.

The NOAA Marine Debris Program staff kicked off Earth Day activities
participating in the 26th Annual Potomac River Watershed Cleanup and the
25th Annual Anacostia Watershed Society Earth Day Cleanup, in Washington
DC, concentrating our efforts throughout watershed. With more than 300
cleanup sites, volunteers dug deep to remove debris and prevent litter
from reaching shorelines. The cleanups attracted more than 5,000
volunteers that helped remove more than 100 tons of debris, which
included everything from cracked bowling balls to piles of tires.
