That's supposed to be a good thing, right? I looked on Google and it suggested the following terms:
"sustainable agriculture", "sustainable architecture", "sustainable business model", "sustainable communities", "sustainable design", "sustainable development", "sustainable energy", "sustainable foods", "sustainable living", "sustainable packaging", "sustainable products" and so forth.
The idea is that you can preface just about anything with the word "sustainable" and it's supposedly better, more environmentally friendly and less wasteful of the earth's resources than the Old Ways.
What you're not supposed to notice is that all of these ideas involve social pressure to conform to top-down ideas being pushed at you in order to inch you towards acceptance of a Third-world standard of living (in exchange for getting to feel morally superior.)
There is one idea that those pushing sustainable solutions have never considered: SUSTAINABLE GOVERNMENT.
After all, it logically follows that if other aspects of society are wasteful and excessive, then government must be as well.
Try mentioning the concept of sustainable government to a liberal/statist in conversation sometime. I promise you they'll be stumbling over the conceptual contradictions you've thrown underfoot and it'll be fun to watch.
