Why this phrase? Two reasons:

Womb ecology reflects world ecology. World ecology reflects womb ecology.

And this (already used in several past posts):

When women are faced each day with enforced cesarean deliveries, birth control that maims and kills them, and doctors who think them dirty, when we encounter rape, violence in the streets, job discrimination, sexual slavery around the world, pollution and nuclear madness, we realize that reclaiming the integrative ways of our ancestors must involve our healing powers on all fronts—from the medical to the social to the environmental to the political to the psychological to the spiritual. Healing the divisions that were imposed during the patriarchal era is the survival issue of our time and our planet. A world that systematically sickens its women cannot survive. [emphasis mine]
