A blog article from the folks at Southern Crafted Homes (which I found through a Twitter alert) starts with a dictionary definition of sustainability and quickly suggests a more simple one:

Resources must be consumed at a rate that allows them to be replenished.

I bring this up because when I talk about our site, earthsayers.tv, and emphasize it highlights the voices of sustainability the first comment is often the question: what is sustainability anyway?  On EarthSayers.tv we are capturing the language of sustainability to include definitions from all kinds of people ranging from environmentalists to designers to politicians.  This one from Southern Crafted Homes is a good one.

The writer also notes there are extremes of sustainability positions among professionals and our citizens, but, again, the writer simply points out:

“…logic tells us that if we extract a resource from the ground and that resource cannot replenish itself then at some point that resource shall cease to exist. The question then is of scale and context.”
