Some pieces
Cut CO2 (we have to decide where)
Make sure those who lose out are helped and at least have basic security and healthy food and shelter
pay attention to energy needs. Not freeze not wett -bulb death, cook food.
Try to keep stronger personalities from shifting resources toward themselves
Keep a community history as best as you can.
Daily community meetings open to all, (learn to use OPEN SPACE technology1)
What it comes down to, everything will change. Look around your room and make an assessment of the use of energy, usually heat, in the making of each one. We can assume never again
Pay attention to history, especially related such as Epicurus and his Garden school in classical Greece, to the Arts and Crafts Movement of the late 1800s. Aesthetic should guide every effort making the space attractive to work play and relax in.
