"It's Coastal Cleanup Day and we're gonna go out and pick up some trash off the beach. There's way too much of it," said one volunteer.

"We're looking a brands and we're looking at packaging, we're seeing how much of it is local, how much is foreign, what might be washing up from out in the ocean and and what people are leaving on the beach so we can find multiple solutions from all angles," said Surfrider volunteer Eva Holman.

But a cleaner coast and a cleaner ocean is the goal for everyone.
