Tiny Plastic Is Everywhere (npr.org)
An anonymous reader shares a report from NPR about ecologist Chelsea Rochman, who has dedicated her career to studying how microplastics are getting into the food chain and affecting everything from beer to fish: Since modern plastic was first mass-produced, 8 billion tons have been manufactured. And when it's thrown away, it doesn't just disappear. Much of it crumbles into small pieces. Scientists call the tiny pieces "microplastics" and define them as objects smaller than 5 millimeters -- about the size of one of the letters on a computer keyboard. Researchers started to pay serious attention to microplastics in the environment about 15 years ago. They're in oceans, rivers and lakes. They're also in soil. Recent research in Germany found that fertilizer made from composted household waste contains microplastics. And, even more concerning, microplastics are in drinking water. In beer. In sea salt. In fish and shellfish. How microplastics get into animals is something of a mystery, and Chelsea Rochman is trying to solve it.
Since she started studying microplastics, Rochman has found them in the outflow from sewage treatment plants. And they've shown up in insects, worms, clams, fish and birds. To study how that happens, [researcher Kennedy Bucci] makes her own microplastics from the morning's collection. She takes a postage stamp-size piece of black plastic from the jar, and grinds it into particles using a coffee grinder. "So this is the plastic that I feed to the fish," she says. The plastic particles go into beakers of water containing fish larvae from fathead minnows, the test-animals of choice in marine toxicology. Tanks full of them line the walls of the lab. Bucci uses a pipette to draw out a bunch of larvae that have already been exposed to these ground-up plastic particles. The larva's gut is translucent. We can see right into it. "You can see kind of a line of black, weirdly shaped black things," she points out. "Those are the microplastics." The larva has ingested them. Rochman says microplastic particles can sicken or even kill larvae and fish in their experiments.

This is true that the descriptions of the "great garbage patch" make it sound like you can walk across it in rubber galoshes.
With that said, the magnitude of plastic being everywhere is well-documented.
Forget the big documentaries or other "propaganda" out there. Just walk around outside in your own neighborhood with a plastic bag for a while. Go to a nearby park or subdivision's "common area" - and pick up every piece of plastic you find. You'll be surprised just how quickly the bag fills up with everything from bottlecaps, car fender chips, McDonald's happy meal toy parts, straws, and all manner of unidentifiable plastic shards.
If those plastic pieces are in the oceans, in the ground, etc. in the same magnitude (or worse), then the scale of the problem isn't being overstated by environmentalists.
One form of microplastics is micro fibers. Microfibers wear off of synthetic clothing every time you take a step, walk down the street, go to the park, go swimming, or do virtually anything else. They banned microbeads because they were getting swallowed by fish, getting into the soils, and getting into the food supply. But the amount of microbeads that were released into the environment is dwarfed by the amount of microfibers released into the environment each and every day. Patagonia of course pretends like they care about our environment but virtually all their products are made from synthetic materials. Their customers hike to some of the most remote places on the earth with some of the worldâ(TM)s most fragile environments littering microfibers all along the way.
It's not a big deal. Just scientists peddling fear for more grant money.
Wow, you are stupid. Lets just consider the motivations of scientists in general. These are generally pretty smart people, who have chosen careers that they know will not make them money the same way that they would were they to go into, say investment banking. A vast majority are going to be motivated by things like curiosity, a passion for the natural environment, discovering truth (regardless of what that truth reveals). None of these things tends to encourage falsifying results, lying to the media, and tricking people into giving them grant money.
Oh sure, there are a few bad apples in every barrel, but they are pretty few and far between. Moreover, other scientists tend to find them pretty quick when they start checking each other's work, because sniffing out the truth is what these people try to do.
I'm not saying they are always right, but only a true idiot doesn't listen carefully to what they have to say.
HA! I just wasted some of your bandwidth with a frivolous sig!
