Scientific American's special edition of March 2009, Earth 3.0, has the tagline, "Solutions for Sustainable Progress." Among many interesting articles, this one, Top 10 Myths about Sustainablity really caught my eye. From the article:

When a word becomes so popular you begin hearing it everywhere, in all sorts of marginally related or even unrelated contexts, it means one of two things. Either the word has devolved into a meaningless cliché, or it has real conceptual heft. “Green” (or, even worse, “going green”) falls squarely into the first category. But “sustainable,” which at first conjures up a similarly vague sense of environmental virtue, actually belongs in the second. True, you hear it applied to everything from cars to agriculture to economics. But that’s because the concept of sustainability is at its heart so simple that it legitimately applies to all these areas and more.

Despite its simplicity, however, sustainability is a concept people have a hard time wrapping their minds around.
