    Fail Microplastics are now in everything including beer, drinking water, food



    Plastic trash is littering the land and fouling rivers and oceans. But what we can see is only a small fraction of what's out there.

    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.

    Rochman is an ecologist at the University of Toronto. She studies how plastic works its way into the food chain, from tiny plankton to fish larvae to fish, including fish we eat.
    She says understanding how plastic gets into fish matters not just to the fish, but to us. "We eat fish that eat plastic," she says. "Are there things that transfer to the tissue? Does the plastic itself transfer to the tissue? Do the chemicals associated with the plastic transfer to the tissue?"

    Rochman says she has always loved cleaning up. She remembers how, as a 6-year-old, she puzzled her parents by volunteering to clean the house.

    In high school in Arizona she got even more ambitious. "I used to take my friends into the desert and clean up a mile of trash every Earth Day," she says. "I remember finding weird old dolls and strange old toys that I thought were creepy, but that I would also keep."
    As a graduate student, she landed a spot on a research vessel to visit the infamous floating garbage patch in the Pacific Ocean. She and the other scientists on the trip were supposed to count the plastic as it drifted by.

    She remembers the moment they sailed into the patch, "Everyone runs up to the bow and says, 'There's trash, there's trash, everyone start counting the trash.' And so we all start counting the trash."

    But something was wrong. "We're looking and it's, like, basically a soup of confetti, of tiny little plastic bits everywhere," she remembers. "Everyone just stops counting. [They] sat there, their backs up against the wall and said, 'OK, this is a real issue, [and it's] not an island of trash you can pick up."
    To Rochman, a third thing was also clear: "The tiny stuff, for me as an ecologist, this is really getting into the food chain. You could spend a career studying this stuff."

    Plastic isn't the only garbage in our water either. I just read that if you drink a quart of water a day, in a year you will have ingested about two pounds of feces.

    I also read that two specific plastics, phthalate and Bisphenol A (which are ubiquitous and leach out of products readily), are all but impossible to avoid ingesting. These plastics have been causing a steady worldwide decrease in sperm count since at least 1970. At the rate of decrease now being observed, males will not be producing ANY sperm by 2040. :O However, the bright side of this issue is that a *"...new technology known as IVG -- in vitro gametogenesis -- is showing early promise at turning embryonic stem cells into sperm. In 2016, Japanese scientists created baby mice by fertilizing normal mouse eggs with sperm CREATED via IVG. The stem cells in question were taken from female mice. There was no need for any males!"

    Oh, somehow I don't greet the idea of planned obsolescence with as much joy as you do.
