Further evidence that plastic does not discriminate as it spreads across the planet: the marine conservation organisation Sea Shepherd said it is washing up in large quantities on a remote Australian beach.

Sea Shepherd joined Indigenous rangers in picking up more than seven tonnes of marine plastic pollution on a two-kilometre stretch of Djulpan beach, in northeastern Arnhem Land.

Using the same analysis technique employed in a recent study that found a staggering amount of rubbish on the tiny Cocos (Keeling) Islands in the Indian Ocean, researchers have estimated there would have been 250m pieces of debris along the full stretch of the 14km beach.

The clean-up of Djulpan beach, about 2 1/2 hours drive from the township of Nhulunbuy on the western side of the Gulf of Carpentaria, was conducted over two weeks last October. There is no road to the beach. The rangers from Dhimurru Aboriginal Corporation cut a 4WD track through scrub to reach it.

Liza Dicks, from Sea Shepherd Australia, said it was the worst case of plastic rubbish the group had found in more than 600 clean-up exercises at mainland Australian beaches.

About two-thirds of the debris were consumer items: water bottles, cigarette lighters, ice block wrappers, shoes, thongs, toys and toothbrushes. The rest was 72 types of discarded fishing net, some of which contained turtle bones.

Jennifer Lavers, a marine biologist at the University of Tasmania who led the Cocos (Keeling) Islands study and helped Sea Shepherd analyse what it found at Djulpan beach, said much of the rubbish was single-use and disposable. Some of the plastic appeared to be decades old.

“It is likely this waste came from southeast Asia, but we know at the same time Australia’s waste is going over to somewhere else,” she said.

“It is incredibly commonplace, but for the average ordinary person it’s probably pretty shocking to learn that these remote pristine places have such a high density of plastic. This is not some untouchable thing. It is a thing we can do something about.”

Last month the prime minister, Scott Morrison, vowed to do more to stop Australian plastic ending up in oceans. He won in principle backing from state and territory leaders to boost the struggling local recycling industry and ban the export of recyclable material.

No timeframe has been set for the ban, which will be discussed at a meeting of environment ministers in November. Government data suggests just 12% of the plastic waste Australians put in kerbside bins is recycled.

Microplastics discovered in ‘extreme’ concentrations in the North Atlantic

https://www.cnn.com/2019/08/19/world/microplastics-sargasso-sea-north-atlantic-intl/index.html

Sargasso Sea (CNN)Within the Atlantic Ocean is the world’s only sea without shores, its borders defined by the currents of the North Atlantic gyre. The Sargasso Sea takes its name from sargassum, a free-floating golden brown seaweed that is a haven for hatchling sea turtles and hundreds of other marine species who use it to feed, grow and hide from predators. But the sargassum is now home to objects wholly unnatural too.

Caught up in the swirling gyre is a growing collection of human waste: trash from countries that border the Atlantic, from the west coast of Africa to the east coast of the US, slowly breaking up on its long journey into microplastics that end up in the gills and stomachs of aquatic animals.
We joined a Greenpeace expedition to the Sargasso where scientists were studying plastic pollution and turtle habitats. Our mission was to get a better understanding of what lives out on the sargassum ecosystem, what is threatening it, and how that may impact us.

Into the blue

My cameraman, Brice Laine, and I thought we had an understanding of how humanity’s reliance on plastic has impacted Earth. We have reported from the remotest regions of our planet, from the Arctic to the Antarctic, where we witnessed the discovery of microplastics, fibers and PFAS (chemicals that are used as stain and water repellents in things like cookware and outdoor gear).
The Sargasso Sea is another place where few humans venture. Constantly changing with the currents, this oval shaped body of water is around 1,000 miles wide and 3,000 miles long. From the bow of our ship, Greenpeace’s Esperanza, the water looks pristine, inviting. Having never really been in waters like this — the open ocean, often believed to be a biodiversity desert — we’re excited to get in.
There are small schools of juvenile trigger and file fish, and other species darting around or just hiding within the sargassum. There are many species we don’t see, too small, too apt at blending into this rich nursery ground like young shrimp and crab, tiny frog fish, and what we really hoped to find but didn’t — baby turtles.
Embedded in most of the sargassum are the easily visible pieces of trash: shampoo bottles, fishing gear, thick hard containers or thin soft bags amongst many other types of plastic. One of the scientists points out fish bite marks in a small plastic sheet we pull out. But what is really jarring is when you dive down and look into the blue and realize you are surrounded by tiny glittering pieces of broken up plastic called microplastic.
It wasn’t until witnessing it that the extent of plastic pollution and what it means sank in. And it’s terrifying.
Greenpeace scientists say they found “extreme” concentrations of microplastic pollution in the Sargasso Sea, although they are still reviewing their findings. In one sample, they discovered almost 1,300 fragments of microplastic — more than the levels found last year in the notorious Great Pacific Garbage Patch.
Their analysis indicates this pollution originates from single-use plastic bottles and plastic packaging, according to Greenpeace.
Greenpeace’s trip to the Sargasso is part of its year-long pole-to-pole expedition to campaign for a Global Ocean Treaty that calls for the protection of a network of ocean sanctuaries covering 30% of the world’s oceans by 2030.
Off the side of the Esperanza, the manta trawl lazily gobbles up water samples from the ocean’s surface that are filtered through its long mesh tail. An hour later, what is collected shows us the bleak reality of what is in the water.
“In most of the samples that we have been sampling where there is sargassum we have seen a lot of plastics because they get entangled in the sargassum,” Celia Ojeda, a marine biologist with a PhD in ocean conservation, explains, pointing to the tiny pieces floating at the top of one sample.
“It’s a really nice blue; you can’t imagine what is under there, and then when you get the sample you get really shocked at the numbers,” she says.
Along with research assistant Shane Antonition, who is with the Bermuda Aquarium Museum and Zoo, Ojeda spends hours picking through the sargassum and what was collected in the manta trawl net.
Grabbing the tiny pieces with tweezers, she places them carefully on paper to count.
Antonition was part of a similar study years ago. “The more I learn, the more I see how much more like a spaceship Earth is, and how fragile these systems are and how much we rely on these ecosystems services to keep us alive. So, (we are) learning more about our impact on the earth and using those discoveries to inform the change that can prevent further degradation of our environment,” he says.

From your bin to your plate, via the ocean

Only around 9% of plastic produced has ever been recycled. Most single-use plastics end up in landfills or are burned in huge toxic fires. Some finds its way into our rivers or the oceans, either flushed into water systems or blown by wind currents.
A close up shot of small pieces of plastic among the Sargassum. Plastics become broken down until they're so small they're consumed by wildlife and enter the food chain.

“This goes into the food chain.” Ojeda explains. “The fish and shrimps eat the plastic, we are eating them or the fish that eat them, and this will end up in our bodies somehow.”
The plastic humans discard — food wrappers, plastic bags, even nappies — find their way back into homes in the food that you buy. A study from June 2019 said the average person ingests around 2,000 microplastic particles a week — around five grams, or the weight of a credit card. What scientists don’t yet fully understand is what that plastic or the toxins that plastic contains can do to us.
Plastic pollution is hardly a new phenomenon. A study off the shore of Bermuda back in the early 1970s found 3,500 pieces of plastic per square kilometer. A more recent, as yet unpublished study by the Bermuda Aquarium Museum and Zoo found that nearly 42% of fish samples had ingested microplastics.
The weight of evidence that humans are contaminating one of our major food sources is overwhelming — not only introducing potential toxins into our own bodies, but also polluting whole ecosystems and killing precious marine animals.

How can you protect the ocean?

The key to tackling ocean plastic is to stop it getting there in the first place, but the solution doesn’t just lie with recycling.
“We need to be reusing and refilling,” Ojeda says. “The consumers are doing a lot of things, but if you as a consumer are going to the supermarket and you are unable to buy something which is not wrapped in plastic it’s not your fault. You are a person. It’s companies; companies need to take the step, need to lead the change — and governments need to push the companies.
“For the oceans to recover to we need to stop them (plastics) now. If we are thinking we can stop them in 10 years, we can phase them out, no: we need to stop single-use plastic. Then the seas will have time to clean up.”

“We need to look at all the ways we are not understanding the fate of plastic,” says Robbie Smith, a marine ecologist and the curator of the Bermuda Aquarium and Zoo. “Recycling is terrible, even in the US. Countries are facing up to the reality, but they are not ready to turn off the tap.
“We need to look at the types of plastic we are using and eliminate the ones that can’t be recycled. We need to tidy up land-based sources (landfills and the like).
“We need to be more respectful that plastic is a great tool but can become a nightmare,” he adds. “There is no quick fix. Nothing is going away fast. It takes a decade or two for plastic to make its way into the watershed.”
Few of us witness what is out in the open oceans far from our homes, which is one of the many challenges for ocean protection and why few truly understand how dire the situation is. Out of sight, out of mind.
But in reality, it’s ending up right back in front of us — and inside us — even though we may not see it.

Wild bees are building their homes from plastic—and scientists aren’t sure why

Sarah Gibbens

Wild bees, nesting in Argentinian crop fields, were recently found constructing nests entirely made of the flimsy plastic packaging material left on farms.

From 2017 to 2018, researchers at Argentina’s National Agricultural Technology Institute crafted wooden, artificial nests for wild bees. Unlike bee species that have a large hive with queens and workers, wild bees burrow into nests to individually lay larvae. The constructed nests fit together like long rectangles with a narrow, hollow opening that allowed wild bees to crawl inside and fill it with cut leaves, twigs, and mud.

Sixty-three wooden nests were constructed, and three were found lined entirely with plastic. Similar in size and shape to a fingernail, the bits of plastic had been carefully cut by bees and arranged in an overlapping pattern in their nests. Based on the material, researchers think the plastic may have come from a plastic bag or film, which has a similar texture to the leaves bees typically use to line their nests.

Of the three plastic nests, one had not been finished, meaning the bee did not use it to lay her larvae, Science Alert reports. In the remaining two, one larva died and the other was not found, leading the researchers to believe it survived.

What does it mean for bees?

This new research, published in the journal Apidologie, documents the first time bees have been seen making nests only out of plastic, but for years scientists have known bees were incorporating plastic into their building materials.

In 2013, a paper published in Ecosphere outlined how bees were using plastic films and foams to line nests in urban areas throughout Toronto, Canada. Similar to the bees in Argentina, the wild bees observed in Canada cut pieces of plastic that resembled the leaves they commonly use.

Notably, the Canadian study found it wasn’t just flaps of plastic bags the bees were using. Plant resins, which can be fashioned into anything from gum to latex, often bind a bee’s building materials together. But some individuals, they observed, were hauling a plastic-based caulk back to their nests to use instead.

Both studies noted that more research needs to be done before scientists can outline the potential impact plastic might have on bees, but the nest building shows that bees are highly adaptive to changing environments. In both places, leaves were readily available as a building material.

“It would demonstrate the adaptive flexibility that certain species of bees would have in the face of changes in environmental conditions,” the study’s lead author Mariana Allasino wrote in a press release translated from Spanish.

Plastic dangers

Hollis Woodard, an entomologist who studies bees at the University of California Riversides Woodard Lab, isn’t surprised to see bees hauling plastic to their nests.

“I think it’s really sad,” she says. “It’s another example of the rampant use of materials that end up in places we don’t intend them to.”

Plastic often presents a threat to wildlife in the form of microplastics, the incredibly tiny bits of plastic that form as larger plastic trash breaks down. Microplastics are a danger to the animals that mistake them for food, which many do, especially in marine environments. No study, however, indicates that bees might be consuming plastic.

Among the dangers that bees face are pesticides, habitat destruction, and exposure to viruses or parasites.

Researchers have speculated that plastic may form a barrier against common nest issues like mold and parasites.

If the bees are in fact choosing plastic over natural materials, it wouldn’t be the first time animals have used trash to their advantage.

Sparrows and finches line their nests with cigarette butts to ward off parasitic mites, and black kites in the Italian Alps collect bright strips of plastic to decorate their nests and attract mates.

“It would take a lot more research to know what this means for the bees themselves,” says Woodard. “Sure it’s possible it might afford some benefits, but that hasn’t been shown yet. I think it’s equally likely to have things that are harmful.”

Turns out there’s more plastic pollution in the deep ocean than the Great Pacific Garbage Patch

SAN FRANCISCO — The problem of plastic pollution in the ocean is even worse than anyone feared. Tiny broken up pieces of plastic — microplastic — aren’t just floating at the water’s surface but are pervasive down thousands of feet. There’s actually more microplastic 1,000 feet down than there is in the Great Pacific Garbage Patch, research published Thursday found.

“We didn’t think there would be four times as much plastic floating at depth than at the surface,” said Kyle Van Houtan, chief scientist at the Monterey Bay Aquarium.

He’s one of the authors of the study published in this week’s edition of Scientific Reports from the journal Nature that investigated just how much plastic there is in the ocean’s depths.

Literally tons of plastic trash wash down rivers and out to sea each day, fouling the surface and endangering sea life. It’s long been believed that most of it floated. But when the researchers looked deep below the surface, they found tiny broken-down plastic pieces, smaller than rice grains, wherever they looked.

The issue of plastic ocean trash has been a focus of public concern over the past decade, a concern that’s centered on the Great Pacific Garbage Patch. That’s a huge floating blob of plastic trash halfway between California and Hawaii drawn together by ocean currents to create a gyre. This vortex of waves concentrates the floating trash pieces in an area twice the size of Texas.

It’s important to remember that the patch isn’t composed of big floating rafts of trash, but rather a pervasive almost mist of tiny bits of plastic floating in the water. Think of it more as a fog in the water than as a bleach bottle bobbing along.

That same fog of plastic bits extends deep down below the surface, the scientists found. And deeper down, it’s worse than at the surface.

Previous research found concentrations of microplastic in the Great Pacific Garbage Patch were about 12 particles per cubic meter of water. “We topped out at 16,” said Van Houtan of his team’s underwater findings.

The deep-sea methods they used were highly innovative, and confirmed a bleak picture of what the last decade’s research has been pointing toward, said Brendan Godley, a conservation scientist who studies plastic ocean pollution at the University of Exeter in the United Kingdom.

“Scientists are now beginning to realize that microplastics are truly ubiquitous. They’ve been found from the seafloor to the mountain tops, in the air we breathe and in the salt we put on our meals,” he said.

The biggest shock of all, says Peter Ross, a toxicologist who studies the impacts of microplastics on marine life at Canada’s Vancouver Aquarium in Vancouver, British Columbia, is that it’s not a surprise at all how much plastic there was even deep down in the ocean.

“This research demonstrates the way in which we’ve gone from zero understanding of the problem 15 years ago to full-fledged appreciation that this pollutant is completely distributed around our entire planet,” he said.

What they found

The researchers used drone micro-submarines to sample the water from the surface all the way down to the ocean floor, 3,200 feet. The sample area included one site near Monterey Bay on the California coast and one site 15 miles offshore.

The highest concentrations of microplastics were between 600 and 2,000 feet down.

They also inspected the guts of red pelagic crabs and a kind of jellyfish-like filter feeders called a giant larvacean. Both species play key roles in ocean food webs, from the surface to the seafloor. Every one of them contained plastic.

“Even if you don’t care about the crabs and the larvaceans, they’re the food of things you do care about – tuna, seabirds, whales and turtles all feed on them, or feed on things that feed on them,” said Anela Choy, a professor at the Scripps Institution of Oceanography at the University of California, San Diego and one of the paper’s authors.

While they sampled just two areas, Van Houtan believes they would find similar patterns given ocean currents and the ongoing mix of waters.

Laser spectroscopy allowed them to analyze what kind of plastic each of the particles they found came from, which also turned up some surprises.

Some have suggested that the majority of plastic in the sea comes from discarded or lost commercial fishing gear. However the researchers found that very few particles were from fishing gear. Almost all were from terrestrial sources.

The one piece of good news Van Houtan found in what they saw was that the single largest type of plastic they found floating in the water – about 40% – came from single-use plastics such as beverage and food containers.

“That’s something we as consumers can do something about,” Van Houtan said. “Single-use products are something that we can demand better alternatives for.”

Malaysia to Ship Plastic Trash Back to the U.S., Other Origin Countries

The country will send roughly 3,300 tons of plastic waste to countries like the U.S., its environment minister announced.

Based on a study by McKinsey and Co. and Ocean Conservancy, Indonesia is the number two plastic waste producing country in the world after China. The large amount of waste production, especially plastics sent to the Indonesian seas, directly contributes to making coastal areas and small islands dirty and full of garbage. Moreover, from the results of the study, it was found that the waste in the coastal area was dominated by plastic with a percentage of 36 to 38 percent.

MALAYSIA PLANS TO SEND back roughly 3,300 tons of plastic trash to countries like the U.S. and Canada, its environmental minister announced Tuesday.

After China banned the import of plastic waste last year, Malaysia and other developing countries became the destination for much of the world’s trash.

Environment Minister Yeo Bee Yin said the country will be sending 60 containers of waste back to their countries of origin. They were discovered while they were being smuggled to illegal processing facilities.

“These containers were illegally brought into the country under false declaration and other offences which clearly violates our environmental law,” Yeo said.

China Doesn’t Want Your Trash

Yeo added that many citizens in developed countries were mostly unaware that their trash – which they think is being recycled – is actually being dumped in Malaysia.

“We are urging developed nations to review their management of plastic waste and stop shipping garbage to developing countries,” she said. “If you ship to Malaysia, we will return it back without mercy.”

At least 14 countries, including the U.S., Canada, Japan, France, Australia, Saudi Arabia and China, will get trash shipped back to them, according to Malaysian officials.

The move makes Malaysia the latest Asian country to start rejecting other nations’ trash.

Last week the president of the Philippines said he would send back 69 containers of garbage to Canada to be left in international waters if the country doesn’t accept them.

As the world grapples with what to do with its trash, many nations have promised to try to address the problem.

Earlier this month more than 180 countries pledged to meet control measures to curb plastic pollution under the Basel Convention. The U.S. was not one of them.

Items that can’t be recycled are usually burnt or put into landfills, contaminating air, dirt and water sources.

More states aim to join Florida to knock air out of festive balloon launches

 – The tradition of releasing balloons at weddings, birthdays and memorials may soon get deflated by lawmakers in more than half a dozen states.

Critics say the helium-filled balloons pollute the environment, and threaten birds and other wildlife when they fall to earth. In Florida, if ten or more balloons are released at once, it could lead to a $250 fine.

“People don’t really realize that it’s littering. That’s why we want to bring attention to this,” said state Rep. Lydia Blume, who’s supporting a balloon bill in Maine. “It’s a common sense thing.”

Earlier last week, a baby dolphin was euthanized. Biologists said the found two plastic bags and a shredded balloon during a necropsy.

“This finding highlights the need to reduce single use plastic and to not release balloons into the environment,” explained the Florida Fish and Wildlife Conservation Commission in a Facebook post.

Nationwide, there’s a growing awareness of the problem, and it has energized legislation in state governments. Bills to limit the intentional release of large numbers of balloons are being aired in legislatures in Arizona, Connecticut, Massachusetts, New Hampshire, New Jersey, New York and Rhode Island, in addition to Maine, said Jennifer Schultz of the National Conference of State Legislatures.

Texas is also considering a study on windblown and waterborne litter that would include helium balloons, she said. A similar proposal was terminated while in committee in the Kentucky legislature last month.

These states would join California, Connecticut, Florida, Tennessee and Virginia – all of which already have laws that ban or restrict launches. California’s law applies only to foil balloons, while Connecticut is currently considering a stricter law, said Danielle Vosburgh, a Florida environmental activist who helped launch a nonprofit organization, Balloons Blow.

Maine’s proposal to ban mass balloon releases took flight at a town meeting last month in Unity. Penny Sampson, chairwoman of the Select Board, said she had witnessed a couple releases in person. Once was in 2000 when triplet boys died in a fire in Unity. Another time, balloons were released at the Wiscasset Raceway to memorialize someone who died.

“To pollute the environment and cause marine and wildlife issues is really not a good way to memorialize someone. There are plenty of other ways to do it,” Sampson said.

Critics are having some recent success in battling the feel-good tradition of releasing balloons. Clemson University stopped releasing balloons at its football games. The Indianapolis 500 and the Nebraska Cornhuskers have faced pressure to do the same.

And a growing number of communities are tackling the issue, too.

The New Jersey-based Balloon Council, which represents manufacturers, wholesalers, distributors and retailers, used to be opposed to bans on balloon releases because of the impact on small businesses. These days, the council still prefers education over legislation, but it is not opposing any of the legislative efforts to stop balloon releases.

“The balloon council feels that all balloons should be deflated and properly disposed of,” said spokeswoman Lorna O’Hara. “There is a heightened attention across the globe. We’re rising to what’s happening in the United States and globally.”

Some folks are getting the message – with or without legislative intervention.

At Fort Leavenworth, Kansas, officials at the Army installation quickly decreed there will be no more balloon releases after children released balloons on April 1 to mark the “month of the military child.” The balloon launch caused an uproar in the community.

“We’ve been beaten up on social media,” said base spokesman Jeffrey Wingo.

But the outrage sparked a discussion about environmental stewardship. “Is this the right thing to do? Is this environmentally sound, or not?” he said. “It is not.”

Deadliest plastic trash ingested by seabirds revealed in new study

Balloons ingested by seabirds are more deadly to them than hard plastics, a study released last week concluded.

Studying the cause of death of more than 1,700 seabirds, researchers from the Institute for Marine and Antarctic Studies (IMAS) at the University of Tasmania and other organizations concluded balloons are the “highest-risk plastic debris item for seabirds,” a statement regarding the study’s findings, which were published in the journal Scientific Reports on March 1, states.

DUCKS, GEESE IN COLORADO DYING FROM ‘NEW DUCK DISEASE,’ PROMPTING WARNING FROM WILDLIFE OFFICIALS

Of the 1,733 seabirds studied, scientists found that one in three of the birds had ingested marine debris prior to its death.

Though hard plastic typically accounts for the majority of marine debris ingested by seabirds, it is “far less likely to kill than soft plastics such as balloons,” the researchers concluded, according to the statement. In fact, balloons are “32 times more likely to kill than ingesting hard plastics,” they found.

“Among the birds we studied the leading cause of death was blockage of the gastrointestinal tract, followed by infections or other complications caused by gastrointestinal obstructions. Although soft plastics accounted for just 5 percent of the items ingested they were responsible for more than 40 percent of the mortalities,” the study’s lead author and a doctoral candidate with IMAS, Lauren Roman, said in the statement.

“Balloons or balloon fragments were the marine debris most likely to cause mortality, and they killed almost one in five of the seabirds that ingested them,” she continued, noting researchers hypothesized hard plastic fragments pass quickly through the bird’s gut while soft plastics “are likely to become compacted and cause fatal obstructions.”

The researchers said their findings “have significant implications for quantifying seabird mortality due to debris ingestion, and provide identifiable policy targets aimed to reduce mortality for threatened species worldwide.”
