...there's no such thing as sustainability. There are just levels of it. It's a process, not a real goal. All you can do is work toward it. There's no such thing as any sustainable economy. The only thing I know that's even close to sustainable economic activity would be organic farming on a very small scale or hunting and gathering on a very small scale. And manufacturing, you end up with way more waste than you end up with finished product. It's totally unsustainable. It's just the way it is.
