10 Most Common Types of Beach Litter Are All Plastic

The Ocean Conservancy released on Wednesday its International Coastal Cleanup (ICC) report, a compilation of litter collected from a one-day cleanup of beaches and waterways worldwide.

For the first time since the report's inception more than 30 years ago, the 10 most common items picked up by volunteers around the world were made of plastic. Foam takeaway containers booted glass beverage bottles from this year's list.


"Over the years, we have seen plastics creeping into the top-10 list, displacing items like rope, beverage cans and paper bags," said Nicholas Mallos, director of Ocean Conservancy's Trash Free Seas program, in a statement provided to EcoWatch. "But this is the first year that all ten of the top-10 items collected are made of plastic. Given that plastic production is rising, this could be the start of a long and troubling trend."

During last year's International Coastal Cleanup Day, which is observed annually on the third Saturday in September, nearly 800,000 volunteers in more than 100 countries collected nearly 20.5 million pounds of trash.

Participants found that cigarette butts—a repeat top offender on the ICC list—were the most littered item, with approximately 2.4 million collected. Food wrappers (1.7 million pieces), drink bottles (1.6 million), bottle caps (1.1 million) and grocery bags (757,523) round out the top five.

Each piece of debris is logged into Ocean Conservancy's Ocean Trash Index, the world's largest database on marine debris, a valuable snapshot of the world's growing plastic problem.

"What sets the ICC apart is our emphasis on data collection," said George Leonard, Ocean Conservancy's chief scientist in a statement, "and data are critically needed if we are to find meaningful solutions to the ocean plastic crisis."

Since about 1950, humans have created more than 8.3 billion metric tons of new plastics. Unfortunately, a lot of that plastic ends up in the world's oceans. An estimated 8 million metric tons of plastic leaches into our seas each year. This debris has negatively impacted more than 800 species of marine animals, a UN report found.

Plastic also never fully biodegrades; it just breaks up into smaller and smaller pieces. These microplastics, which get gobbled up by plankton and fish and work its way up the food chain, have been found in all corners of Earth. A recent Greenpeace expedition to Antarctica turned up microplastics in more than half of ocean water samples taken in the world's southernmost waters.

While the growing international effort to ban single-use plastics is crucial in curbing use of the material, beach cleanups are important because they directly stop the flow of plastics from entering our precious waters.

As Allison Schutes, associate director of Ocean Conservancy's Trash Free Seas program, puts it, "Every item of debris removed is one less item putting ocean wildlife at risk."

This year's International Coastal Cleanup will be held on Sep. 15. Click here to find a cleanup near you.

Changing the Main Course of Climate Change

By Chloë Waterman

As the Trump administration's dangerous deregulatory agenda leads us closer to climate catastrophe, cities, counties and businesses are stepping up to address the crisis. Last month, Gov. Jerry Brown and former New York City Mayor Michael Bloomberg released their "Fulfilling America's Pledge" plan, laying out the top climate strategies for subnational governments and businesses, at the Global Climate Action Summit.

27 Injured, 300,000 Without Power as Leslie Becomes Strongest Storm to Hit Iberian Peninsula Since 1842

Leslie became the rare named Atlantic tropical system to hit Europe late Saturday when it rammed into Portugal as a post-tropical cyclone, injuring 27 and leaving more than 300,000 without power, The Associated Press reported Sunday.

Leslie had been downgraded from a Category One hurricane before making landfall, but it still lashed Portugal with hurricane-force winds. The seaside town of Figueira da Foz recorded wind speeds of 105 miles per hour.

Somehow the striking blue-throated hillstar, a hummingbird with an emerald-feathered head and sapphire splash across its neck, managed to elude us for a very long time. Scientists just recently discovered Oreotrochilus cyanolaemus, describing the species for the first time in The Auk: Ornithological Advances.

Top 10 Greenest Cities in America

San Diegans, pat yourselves on the back. Your city was ranked as 2018's "greenest city" in the U.S., beating out perennially crunchy San Franciscans by less than a point, according to WalletHub's calculations.

In a report released this week, the personal finance website compared the 100 most populated U.S. cities across 26 key "green" indicators, from greenhouse gas emissions per capita to share of electricity from renewable sources. Even the number of farmers markets and green job opportunities were considered.
