A ten thousand year civilization of patriarchal empire has domesticated a third of the world’s population and enslaved most of the rest of us through increasingly invasive means of disconnection. The most sustainable (and subversive) thing you can do is connect. Connect with yourself. Connect with other people. Connect with the Earth.
Think of modern school where students are divided according to age. In sustainable school the older children naturally teach younger children, deepening their own understanding. Modern school taught us to cut off from our imagination and submit our creative intelligence to an all knowing authority. Alone we competed against others for grades. In sustainable school students succeed by helping each other learn. Imagine that.
