Clean is a relative term, says Eveline Bravo, programs manager for Heal the Bay, a nonprofit pro-environment organization hellbent on restoring Santa Monica Bay.

"There's so much Styrofoam and plastic and it's hard to feel like you're not just making small dents."

Yet every third Saturday, Bravo — along with hundreds of other volunteers — shows up at designated beaches with buckets in hand.

The monthly Nothin' But Sand event brings everyone together to pick-up trash, record findings for the Marine Debris Database and learn how to keep trash out of the ocean in the first place.
