Turtles’ Tummies Found Clogged with Plastic

Turtles’ Tummies Found Clogged with Plastic

SOURCE: Hakai Magazine DATE: December 10, 2018 SNIP: Tiny pieces of plastic in the ocean are killing juvenile loggerhead turtles, a new study shows, threatening the survival of the endangered species. Wind, waves, and sunshine break down discarded plastic—from water bottles to fishing gear—into tiny pieces. About 90 percent of the estimated 150 million tonnes of plastic that litters the ocean measures less than five millimeters across, or about half the width of a pinky finger. Plastic like this can now be found littering a brown seaweed called sargassum, in which loggerhead turtles forage for food. For the new study, Evan White of the New Materials Institute at the University of Georgia examined the gastrointestinal tracts of 52 turtles that died at only days or months old and found that 48 contained plastic. The plastic bits, which were up to a millimeter wide, were sometimes lodged in the turtles’ narrow, winding intestines, blocking the passage of food. The blockages were enough to cause the turtles to starve. The plastic was just a tiny percentage of their body weight, but enough to kill them. Juno Beach is one of the world’s most densely nested sea turtle sites. One of every 20 loggerhead turtles on the planet starts its life here. The beach is also littered with plastic. On a recent November survey, for instance, a team of center volunteers found dozens of plastic fragments, including pieces of straws, bottle caps, a comb, and even Chinese sausage packaging. The study’s findings show how serious the dangers of microplastic are to the survival of loggerhead turtles, says Jeanette Wyneken, a biologist at...
Researchers find plastic particles in every sea turtle tested for study

Researchers find plastic particles in every sea turtle tested for study

SOURCE: Axios DATE: December 5, 2018 SNIP: Research published in the journal Global Change Biology revealed that more than 800 synthetic particles, including “microplastics,” were found in the digestive systems of 102 sea turtles examined from 3 ocean basins. The fact that microplastics were found in all of the turtles tested by researchers — in oceans all across the world — highlights the impact of marine plastic waste and its potential effects on animals. The study estimated that between 4.8 and 12.7 million tons of plastic waste could enter the world’s waters each year. The sea turtles were pulled from seven species from across the Atlantic and Pacific oceans as well as the Mediterranean Sea. They performed necropsies on the turtles, examining their “gut content.” The samples extracted only provide a look at a portion of the turtles’ gut content, indicating that the actual synthetic particle content throughout a turtle’s whole gut is likely to be 20 times...
Indonesia: dead whale had 1,000 pieces of plastic in stomach

Indonesia: dead whale had 1,000 pieces of plastic in stomach

SOURCE: The Guardian DATE: November 20, 2018 SNIP: A dead whale that washed ashore in eastern Indonesia had a large lump of plastic waste in its stomach, including flip-flops and 115 drinking cups, a park official has said, causing concern among environmentalists and government officials in one of the world’s largest plastic polluting countries. Rescuers from Wakatobi national park found the rotting carcass of the 9.5 metre (31ft) sperm whale on Monday near the park in Southeast Sulawesi province after receiving a report from environmentalists that villagers had surrounded the dead whale and were beginning to butcher the rotting carcass, park chief Heri Santoso said. Santoso said researchers from wildlife conservation group WWF and the park’s conservation academy found about 5.9kg (13lbs) of plastic waste in the animal’s stomach containing 115 plastic cups, four plastic bottles, 25 plastic bags, two flip-flops, a nylon sack and more than 1,000 other assorted pieces of plastic. Indonesia, an archipelago of 260 million people, is the world’s second-largest plastic polluter after China, according to a study published in the journal Science in January. It produces 3.2 million tons of mismanaged plastic waste a year, of which 1.29m tons ends up in the ocean, the study...
Plastic Pollution Has Increased a Hundredfold in the South Atlantic

Plastic Pollution Has Increased a Hundredfold in the South Atlantic

SOURCE: Nexus Media DATE: October 17, 2018 SNIP: Thirty years ago, the ocean waters surrounding British islands in the South Atlantic were near-pristine. But plastic waste has increased a hundredfold since then, and is ten times greater than it was a decade ago. These islands — part of the British Overseas Territories, which includes established or proposed Marine Protection Areas — are among the most remote on the planet. Yet they no longer are immune to the kind of pollution fouling industrialized North Atlantic coasts, a fact that portends dire consequences, according to new research. The plastic is of many types and from many sources, including debris blown in from landfills, trash tossed out by thoughtless beachgoers, detritus from the shipping and fishing industries, and other bits and bobs carried off by severe storms or other accidents, according to Barnes. “Millions of microplastics can form from degradation of a single larger piece, such as a plastic bag,” he said. [D]egrading plastics emit such greenhouse gases like methane and ethylene when exposed to sunlight, further worsening climate change. “Climate change is tied up with plastic as a threat to biodiversity — life on Earth — in a number of different ways,” said Barnes, lead author of the study, which appears in the journal Current Biology. Andy Schofield, a biologist with the Royal Society for the Protection of Birds, and one of the researchers on the project, agreed. “These islands and the ocean around them are sentinels of our planet’s health,” he said. “It is heart-breaking watching Albatrosses trying to eat plastic thousands of miles from anywhere. This is a very big wake up call. Inaction threatens not just...

‘A single piece of plastic’ can kill sea turtles, says study

SOURCE: BBC DATE: September 13, 2018 SNIP: A new study suggests that ingesting even a single piece of plastic can be deadly for sea turtles. Researchers found there was a one in five chance of death for a turtle who consumed just one item – rising to 50% for 14 pieces. The team found that younger turtles are at a higher risk of dying from exposure to plastic than adults. The authors say their research raises concerns over the long term survival of some turtle species. The never ending surge of plastic into the world’s oceans is taking an increasing toll on iconic marine species. The authors of this study estimate that around half of all the sea turtles on the planet have ingested plastic – this rises to 90% among juvenile green sea turtles off the coast of Brazil. While sea turtles can live until they are about 80 and reproduce for decades, researchers are concerned for the longer term impact of so many juveniles consuming so much plastic. “We know that disproportionately finding it more in younger animals who won’t make it to the reproductive state will have long term consequences for the survival of the species,” said Dr Hardesty. “It’s very...
