I just learned, via the blog Fake Plastic Fish, that not long after my post about the Great Pacific Garbage Patch, another journey to the North Pacific Gyre launched, this time on a vessel made in large part of plastic bottles. Read all about the educational effort buoying it here.
And enjoy this related graphic from Klas Ernflo, via Digg:
I've been thinking about bags—and, more generally, plastic—a lot lately, and not just because of BPA.
For one thing, the final phase of San Francisco's plastic-bag ban just went into effect: as of yesterday, pharmacies can no longer hand out their heretofore fave kind of sack. For another, I just read this post from Sightline Daily (via Terrapass's blog), which contends that the importance of the paper vs. plastic choice is dwarfed by the choice of what you put in the bag.
That may be true in the embodied-energy sense—embodied energy being what's required to manufacture, supply to the point of use, and disassemble or dispose of something. But the unfortunate fact is that lots of bags and other plastic items never get properly disposed of (whatever that means) and instead end up polluting our oceans. A great number of them congregate in what's known as the Great Pacific Garbage Patch.
Two web videos explore that floating dump in compelling ways. The first episode of "Gorilla in the Greenhouse," SustainLane's web-video series for kids, raises awareness about the Great Pacific Garbage Patch and the evils of plastic pollution at the same time as it promotes eco-consciousness and action on the part of the next generation.
For the grown-up set, there's "Garbage Island," a 12-part VBS.TV series in which a group of "non-hippie environmentalists" takes a three-week boat trip to the North Pacific Gyre to find the garbage patch and analyze its waters. What surprised them (and me as well) was that the patch is not actually a visible clump the size of Texas; rather, it's a dense accumulation of debris (the size of Texas). "I came out here expecting to see a trash dump, with pieces you could pull out of the water," the narrator says. "But what I got was an even ruder awakening. Looking out, you don't see the garbage; most of the time you just see the water. But what's in the water is 1,000 times worse than a Coke bottle. It's every part of a Coke bottle busted down into a little digestible morsel."
The plastic in the Great Pacific Garbage Patch disintegrates into its component polymers, and those broken-down bits act as a sponge for persistent organic pollutants. The
horrifying realization is that the garbage patch represents much more than pollution; our castoffs
have actually changed the composition of the ocean, in not-so-nice ways. As the narrator puts it, "It's not a matter of pulling shit out [of the water]; it's preparing our systems for the change that's on its way. It's part of the ocean now. We've consigned ourselves to eating our own shit."
Pretty sobering stuff. In fact, you might want to watch the more-upbeat "Gorilla" afterward. That way you can imagine all the kiddies of today getting inspired, and then becoming savvy, and growing up to find ways to deal effectively with the change that's on its way.
Two BPA-themed e-newsletters just landed in my in-box. The Center for a New American Dream’s dispatch mentions a helpful site, the Bisphenol A Portal, which compiles news reports about the endocrine-disrupting chemical. Particularly helpful is the site’s Smart Plastics Guide (pdf), which breaks down what all those numbers on plastic containers mean and gives tips on how to avoid BPA.
The most recent e-newsletter from the Environmental Working Group’s points to the BPA cheatsheet on its Enviroblog. Interestingly, the central graphic used on that page is a water bottle made by Nalgene, which recently announced that it will phase out production of BPA-containing bottles.
Someone just forwarded me a great resource for parents who are concerned about all this BPA business: a blog called Z Recommends and its report on BPA in children’s feeding products, which rates makers of products such as pacifiers and sippy cups. Besides the online directory, there’s a mobile component. Just text-message “zrecs” followed by the name of the company you’re curious about to 69866 to receive info on your cell phone.
The blog points out one problem that I’d never considered: while the main functional part of any given children’s product may indeed be BPA-free, that’s not necessarily true of the item’s other parts, which are equally likely to end up in kids’ mouths. The “shield” on a pacifier, for example, isn’t meant to be sucked on, but we all know how that goes. Said shields are often made of polycarbonate plastic, which contains the endocrine-disrupting chemical.
The ratings—there are four categories, ranging from Excellent to Poor—are based on “product quality, innovation, the range of products a
company offers, their stance on BPA and their openness about sharing
information about their products.” Z Recommends also provides a list of companies whose wares are all BPA-free, so you can trust anything they make. I found it heartening that there are 30 names on that list.
Z Recommends isn’t just for parents, by the way. It’s chock-full of informative posts such as this one, which talks about Wal-Mart U.S., Nalgene, and BPA-related company claims that warrant skepticism.
Finally the mainstream media is talking about bisphenol A (BPA), a chemical found in many plastics, in light of a new brief by the National Toxicology Program that expresses concern over the substance. As the report puts it, “the possibility that bisphenol A may impact human development cannot be dismissed.”
It’s especially nice to see more light being shed on the fact that the FDA based its sketchy “BPA is safe” stance on two studies funded by the plastic industry [link], ignoring hundreds of government and academic studies that raised red flags about BPA.
In my recent post about the chemical, I expressed surprise to learn that it’s found not only in baby bottles but also in aluminum food cans and beverage cans and bottles. Turns out it’s in numerous other everyday objects, such as CDs, too. Today's Washington Post story on the issue quotes an overseer of the report as saying, “It’s everywhere.... Your cell phone is probably made out of it.”
In Canada, as the New York Times reports, the government is expected to label it toxic in the coming days. Meanwhile, big retailers there, such as Wal-Mart and Home Depot, are already pulling BPA-containing products from their shelves.
Much of the focus in recent reports is on BPA’s presence in baby bottles, sippy cups, and infant formula containers. That’s as it should be, since developing bodies are more affected by endocrine disruptors than adult bodies are.
The Washington Post story points out that BornFree, a company that makes BPA-free baby bottles, can’t keep up with demand. I don’t know about other parents, though, but I’m sticking to glass bottles. Today it’s BPA, but tomorrow...?
Not to be outdone by the FDA, the EPA is being grilled by Reps. John Dingell and Bart Stupak about possible conflicts of interest in advisory panels assessing the human health effects of toxic chemicals.
Meanwhile, speaking of toxic chemicals, my friend Evan sent me this link to an interesting PBS piece on phthalates in toys sold in the U.S.
More bisphenol A blues: This story from the Milwaukee Journal Sentinel reports that the FDA deemed BPA to be safe at current exposure levels based on two studies ... paid for by an arm of the trade group the American Chemistry Council.
Change is good
