In its 2008 heyday, the blog Stuff White People Like took aim at the ubiquity of "outdoor performance clothes"—people's penchant for marching down city streets and suburban strip malls dressed as if they were slogging the Appalachian Trail.
It turns out, our devotion to outdoor wear might be more than just a crime against fashion. It might also be a crime against the outdoors itself—or at least, that vast swath of it that's covered by ocean.
In the meantime, it looks like people should put away their fleeces and focus on fibers like wool and cotton—organically produced when possible. The best way to minimize their impact is to simply consume less of them. According to Institute for Local Reliance researcher Stacy Mitchell, "In the mid-1990s, the average American bought 28 items of clothing a year. Today, we buy 59 items." I predict that we have only begun to reckon with the ecological consequences of that trend.
