A new report says the world's beaches and shores are strewn with trash.

Volunteers scoured 33,000 miles of shoreline worldwide and found 6 million pounds of debris. It ranged from cigarette butts and food wrappers to abandoned fishing lines and plastic bags.

The report released today by the Ocean Conservancy catalogs more than 7 million items that were collected on a single day last September. Volunteers had combed shorelines in 76 countries from Bahrain to Bangladesh and in 45 states from the beaches of southern California to the rocky coast of Maine.

Ocean Conservancy president Vikki Spruill says the report serves as a powerful reminder of people's carelessness and how their random actions have a global impact.
