Do a Google search on the Sustainability Movement or Revolution or Lifestyle. Go on Facebook and rabbit trail around, there are thousands of sites and bloggers. From a secular perspective, the origins of the movement are laid out very well in this article. Reading through it, we see it was founded out of the Environmentalist Movement which is in its essence a hard core ideology that has combined nature lovers with anarchists. Before you shut me down, I am not saying all these modern pioneers are anarchists and environmental zealots, I am simply stating that the beginning of sustainability was born out of this movement.
Today, folks from all walks of life are modern day homesteaders. They are bartering with their neighbors, raising chickens and goats, growing their own food, making their own cleaning and hygiene products, and weaning their dependence on Big Food. We find common ground in The Food Babe Army who is pressuring corporations to remove harmful chemicals from their products. The gardening community is afire with the Back to Eden Film and this is where I had my "Aha" moment.
I view everything through my worldview filter. I believe that we are living in the last days and that the Rapture of the Church is imminent. But what of those left behind? What of the Tribulation Saints? How are they going to survive when the Antichrist rules this world? How will they eat, where will they hide?
I believe that God has been making provision for these people for years. Without their knowledge, without their understanding, He has called them out and taught them what they will need to know. He has provided a place for them to hide, a way for them to feed themselves, and an environment where they can be safe.
Since the earliest adopters of this movement are decidedly anti-christian they will be the most well versed and the best established. They know how to harvest rain, build solar ovens, dehydrate food, raise livestock, and build houses from bags of dirt and shipping containers! They even feel that we are on the precipice and are frantically calling on their spiritual leaders to promote sustainability.
As for me and mine, I figure some of my unsaved neighbors will use my garden. Unsaved friends will remember the couple who has been preparing for years and will eat the stashes of survival food stored in bunkers, basements, and modern fall out shelters. God in His mercy knows they will need it.
