I found this in the footnotes:
“As above, so below. Having made nature into an adversary, or at best a pile of “resources,” it is no surprise that we manifest the same relationship within our bodies. The defining diseases of our time are the autoimmune diseases, the somatization of our self-other confusion. Just as the village, the forest, and the planet are inseparable parts of ourselves that we mistake as other, so our immune systems reject our own body tissues. What we do to nature, we do to ourselves, inescapably.”
