WEST PALM BEACH, Florida — Our oceans and waterways have become giant ashtrays.
Nearly seven million pounds of debris was collected from waterways and shorelines around the world during a single day last year, according to a report released Tuesday, with cigarette butts the most common item found.
Nearly 400,000 volunteers scoured about 17,000 miles of coastline, river bottoms and ocean floors during the Ocean Conservancy's 23rd International Coastal Cleanup in September.
The group's report said more than 3.2 million cigarette butts were picked up during last year's efforts. That's followed by about 1.4 million plastic bags, 942,000 food wrappers and containers, and 937,000 caps and lids. Volunteers also collected 26,585 tires, enough for 6,646 cars — and a spare.
Of the 104 participating countries, the U.S. supplied about half the volunteers.
Volunteers collected about 11.4 million items overall, which weighed a total of 6.8 million pounds. They snagged more than 1.3 million cigarette butts in the U.S. alone, about 19,500 fishing nets in the United Kingdom and more than 11,000 diapers in the Philippines.
"Our ocean is sick, and our actions have made it so," said Vikki Spruill, the Ocean Conservancy's president and chief executive. "The evidence turns up every day in dead and injured marine life, littered beaches that discourage tourists, and choked ocean ecosystems."
The group said thousands of marine mammals, sea turtles and birds are injured or killed by ocean trash every year. During the event, participants found 268 marine animals that survived being entangled in debris. But 175 weren't so lucky and died — including a seal wrapped in fishing line near Santa Cruz, California; a juvenile hammerhead shark entangled in fishing line near St. Augustine, Florida; a sea turtle tangled in rope in the west African nation of Ghana; and a penguin entangled in wire in Rio de Janeiro, Brazil.
The majority of trash, the report said, comes from land-based activities, such as discarding of fast food wrappers during beach picnics.
"Your trash may make it to the beach before you do this year," the report said, adding that a wrapper or cigarette butt discarded on an inland city street can quickly wash down storm drains into rivers and eventually flow out to the ocean.
The next cleanup is set for Sept. 19.
