    It’s no secret that an opposition to sustainable living exists. Earlier this year, Texas state brought several SWAT teams to a sustainable community and threatened to shut it down. Each one of the community members were initially handcuffed at gunpoint. It was called “The Garden of Eden Community,” and was totally self sustainable. You can read more about that here http://www.collective-evolution.com/2….

    This time, it’s Robin Speronis that’s come under fire. She lives off the grid in Florida, completely independent of the city’s water and electric system. A few weeks ago, officials ruled her off-grid home illegal. Officials cited the International Property Maintenance Code http://publicecodes.cyberregs.com/ico…, which mandates that homes be connected to an electricity grid and a running water source. That’s just like saying our dependency on corporations isn’t even a choice. The battle to live without most utilities has been ongoing for Robin, the self-sufficient woman has lived for more than a year and a half using solar energy, a propane camping stove and rain water.
