How does extraordinary plastic hold to abolish a sea turtle?

So much thought has been given to how the plastic ingestion affects seabirds, fish and sea turtles during the cooler years. It is logical to remember that naming plastic pieces is detrimental, but researchers were unaware of the importance of the already remarkable plastic or even the assumption that turtle plastic was an instant cause of death. . Carla Howarth, about the experiences of the Australian Broadcasting Network, found that a current brand of sea turtles was trying to understand this, discovering that in some cases, nibbling an appropriate piece of plastic might have been a problem. abolish animals.

In a brand article published in Scientific Reports, scientists examined information about the deaths of 1,000 sea turtles that were stranded on Australian shores, trying to determine the amount of plastic particles alongside release. In the press, researchers from CSIRO (Commonwealth Scientific and Industrial Analysis Organization) in Australia discovered that a turtle had a 22% chance of losing one's life by ingesting a plastic item. Once a turtle gobbles 14 plastic objects, the death rate rises to 50%. Once an animal has eaten 200 plastic death objects, it is important to experience Matt McGrath on the BBC.

Researchers estimate that fifty-two percent of marine turtles worldwide eat plastic in their intestines, but plastic ingestion rates are diversified in the environment. In Uruguay, for example, Howarth found that 100% of sampled turtles had plastic in their intestinal tract.

Plastics decimated the youngest turtles, defined as hatchling turtles, which began to swim and juveniles on a plate scale or smaller. The researchers found that fifty-four percent of introduced turtles and 23% of adolescent turtles had plastic interiors, compared to 16% of adult turtles.

"Smaller, younger turtles stand out undeniably with ocean currents and streaks, as does the remarkable lightweight, floating plastic," says CSIRO chief designer Britta Denise Hardesty at the BBC. "We predict that smaller turtles are less selective in their diet than the perfect adults who eat seagrasses and crustaceans, the younger turtles off shore and the older animals feeding closer to shore.

The physiology of turtles also renders plastics deadly for them, because animals can not regurgitate, no matter how they eat, using their intestines. Even a small piece of plastic trapped in the rotten situation can result in a blockage resulting in death.

All people no longer have the same opinion with the findings of see. Jennifer Lynch, of the National Institute of Requirements and Know-How in Hawaii, has also examined the plastics of turtles, and Karen Weintraub's experience at the Unusual York Times. But unlike turtles that died and beached, she examined healthy animals that had been involuntarily caught by longline fishermen and drowned. In her, she found animals with over 300 plastic objects that were rather healthy. "They ate some plastic, but that did not worry them," said Dr. Lynch about the animals examined. "They swallow it and they make it poo."

This does not mean that plastic is not a problem, but Lynch thinks there is still work to be done to appreciate the physiological results of plastic. She adds that it is very useful to monitor the weight of ingested plastic turtles by differentiating them from the specialization in the number of objects, which can vary enormously in size.

At the next stage of their learning, howarth experience at ABC, the CSIRO team must combine their new information with other knowledge about the occurrence of the problem. Plastic ingestion to help with estimates of the number of turtles per year.

Eating plastic is no longer worth the trouble to face marine reptiles. Last year also showed that fishing line, discarded fishing tools, six-pack rings, ropes, ropes and other plastic particles can be ruffled with turtles and drown. The answer is direction, to prevent the plastic from entering the ocean and cleaning what is already there. Each of these tasks, once again, is easier to recognize than to do, even if at least one of the controversial issues was currently being launched to compare and deal with the grief segment.
