Nearly Every Seabird May Be Eating Plastic By 2050
sciencehabit writes: According to a new study almost every ocean-foraging species of birds may be eating plastic by 2050. In the five large ocean areas known as "garbage patches," each square kilometer of surface water holds almost 600,000 pieces of debris. Sciencemag reports: "By 2050, about 99.8% of the species studied will have eaten plastic, the researchers report online today in the Proceedings of the National Academy of Sciences. Consuming plastic can cause myriad problems, Wilcox says. For example, some types of plastics absorb and concentrate environmental pollutants, he notes. After ingestion, those chemicals can be released into the birds’ digestive tracts, along with chemicals in the plastics that keep them soft and pliable. But plastic bits aren’t always pliable enough to get through a gull’s gut. Most birds have trouble passing large bits of plastic, and they build up in the stomach, sometimes taking up so much room that the birds can’t consume enough food to stay healthy."
With all the industrial food wrapped into plastic containers, human also eat plastic, since almost all plastic leak chemical into the food.
Polyethylene and polypropylene may be the exceptions, but they always come with other chemicals that improve color or plasticity.
A Diet To Die For
One bird feasts on food that would leave most other animals stone dead

Among an average of 528 types of bacterium found on the heads of 50 turkey and black vultures were those that can cause botulism, gangrene, tetanus, septicaemia, blood clots and metastatic abscesses in other animals. And although these birds did not have it, another study found Bacillus anthracis in vulture faeces. It causes anthrax, except in vultures.
Vultures clearly have strong stomachs, in every sense. With an acidity at least ten times that of a human’s, a vulture’s gut destroys a large amount of any potentially pathogenic bacteria that is ingested. Indeed, when the researchers analysed the contents of each bird’s large intestine, they could not detect some 85% of the micro-organisms they had found on its facial skin.
But what remains is hardly benign. The microbial flora in a vulture’s large intestine is dominated by two types of anaerobic faecal bacteria, Clostridia and Fusobacteria, both of which can be deadly to other animals. Some Clostridia species have been responsible for periodic mass die-offs in birds such as ducks, geese and waders (although other species can be beneficial), while Fusobacteria nucleatum is associated with human colon cancer.

[Just because seagulls and vultures can do it, doesn't mean terns and albatrosses can]
By 2050, about 99.8% of the species studied will have eaten plastic
This sounds a lot like the "one in three women around the world will get raped in their lifetime" bullshit figure that has been repeated ad nauseam over the last 10 years by people who couldn't calc.exe their way out of a paper bag.
lucm, indeed.
It's too bad China (who will easily be out-polluting us in years to come) doesn't give two shits about our energy policy
Did you know that last year, China investments in renewable energy was bigger than that of all European countries combined? They accounted for more than 60%of the world's investment in that sector. And it's even bigger in other "green" areas (forest and wildlife protection, etc).
Nobody in China is thrilled by pollution. But over the last decades they had to deal with insane urbanization rates, the constant threat of starvation and other problems that are completely foreign to us, so yes, fighting pollution did not come first, but that doesn't mean they don't care. They just have to juggle many impossible priorities.
lucm, indeed.
