A new report from the Ocean Conservancy shows just how much trash beach visitors are leaving behind in California and around the world.
The NBC4 I-Team was provided with the new report, which tracked the amount of trash cleaned up on beaches in a 24-hour period. In California, which has more than 800 miles of coastline, the items collected weighed an astonishing 840,000 pounds. Volunteers picked up more than 1 million pieces of trash in California -- more than any other state.
One thing immediately stood out.
"For the first time ever of the 33-year history, the top-10 most commonly found items on beaches around the world were all made of plastic," said Nick Mallos, of the Ocean Conservancy.
