A wrong attitude about nature is almost an integral part of our culture, and all the crying we're doing about the environment is going to come to nothing as long as such an attitude persists.--Euell Gibbons, 1972, qtd. in Smith
I'm channeling my Euell Gibbons tonight. Children of the sixties and seventies knew Euell as the craggy naturalist picking cranberries in the snow to add to his GrapeNuts breakfast cereal. We saw him on popular talk and variety shows. And we laughed at Tim Conway's impersonations of him on the Carol Burnett Show.
If you are a child of a different generation, here is a video of one of this iconic forager's commercials to get you up to speed; his cache in popular culture is not greatly diminished today, forty years after his death.
N.B. I was recently scolded by a math professor in my writing group when I insisted that Wikipedia is not a reliable scholarly source. He cited a new academic journal article in which researchers compared the information on the popular free, open-source encyclopedia to more authoritarian sources and claimed Wikipedia is just as accurate as they are. I don't believe it, though I'll often go to the site first to gather information, then verify it with the references given in the text or through my own research. In fact, the pine tree commercial Wikipedia cites is linked to its "source," the video posted above in which cattails are the wild food highlighted. In neither that nor the cranberry commercial is a pine tree mentioned. Ever the librarian and, hopefully, scholar, I maintain that quoting from Wikipedia does not enhance one's credibility whatsoever. That doesn't mean the site is useless; it just doesn't belong in a scholarly bibliography.
See the end of this article for a list of my sources; those providing unique information are also cited within the text of this "episode."
