Living an eco-friendly life along Green principles, reducing my carbon-footprint in all ways possible. I think I manage this fairly well about 95% of the time.
Research has found, and our experience has been, that the way green living spreads most quickly is by modelling it. Friends and neighbours get to see how well the garden grows, taste our food, feel the comfort of the house, see our good health and, if they ask, see the cheaper bills. This tends to inspire them to adopt the same practises.
Things like loving-kindness, consideration, honesty and responsibility also tend to spread by example because people feel better after experiencing them.
