AUGUST 19, 2013 -- Worried about the amount of trash on our coasts? Do gyres of bobbing plastic whirl through your head each night? Help wipe these worries from your mind and the beach by joining the International Coastal Cleanup on September 21, 2013. With more than 550,000 volunteers scouring beaches, rivers, and lakes last year, this event is the biggest one-day cleanup of marine debris in the world. In the past, volunteers have turned up everything from bottle caps and plastic bags to toilet seats and cyborg sea-kitties. But each year cigarette butts take home the prize for most common item of debris found on the beach, with 2,117,931 of these toxic pieces of plastic turning up during the 2012 global cleanup alone. To volunteer at a location near you, visit Ocean Conservancy online. The NOAA Marine Debris Program is a proud sponsor of the annual event, and last year NOAA volunteers cleaned up more than 2.8 tons (nearly 5,700 pounds) of debris from waterways and beaches in DC, Seattle, and Oahu. Even if you can't make it to your nearest waterway on September 21, you can still help reduce how much trash makes it to the ocean by planning your own beach cleanup and considering these 10 suggestions from Ocean Conservancy:
