I divide environmental topics into two sometimes overlapping groups, “romance” and “sludge.” The romance sector includes parks, forests, wildlands, wilderness, wildlife, and scenic vistas. These treasures grace calendars and coffee table books. Most educated and comfortable adults, even committed urbanites, are attracted to and want to protect this sector.
The second division is sludge. This term refers to nasty stuff that is often the necessary byproduct of legitimate productive activities such as food processing, mining, and manufacturing. These are spillovers from legitimate and useful activities.Economists call this category negative externalities. They ask: How might we efficiently reduce them—or even better, convert them into useful products?
That’s exactly what environmental entrepreneurs did when they converted the wood waste and scrap from lumber mills into valuable wood panels. Those panels replaced plywood—which had replaced boards formerly cut from old growth trees. Lesson here? In a market process economy, superior substitutes naturally evolve.
We can’t live without some sludge; it’s inherent in living and using products from the earth. While recognizing this, I choose to work in the romance arena. Had I elected to focus on sludge, I’d live in Boston and study its harbor. Instead, I live on a ranch between Bozeman and Yellowstone Park and study my surrounding habitat. Thus, I work in the tradition of America’s first conservationists.
America’s old-line conservation organizations were primarily concerned with the romance sector of their environment, largely with protecting wildlife.
