I’ve love to think that the small changes will turn into large changes. That we should become the changes we want to see in the world.
To think that eventually it will make a difference.
On a small scale, yes sustainability can be accomplished for the few who really put forth the effort to participate.
For the vast majority though, they will be happy to be spoon fed with mass produced ‘step on your neighbor’ to get ahead mentality.
In good time, more people will come to sustainable living as they see resources being depleted.
On the other hand, plenty will become violent, and hoard the remaining resources for themselves.
Look at Earthships for example. A beautiful, sustainable way to craft affordable and self-sufficient housing. The amount of red tape to build one of these is astounding, in favor of mass produced , carconegenic structures that require being plugged into the system.
