To a large extent human agency is now part of the evolutionary story. The future of the tree of life is now at the mercy of human decision and indecision. If ever there were a sign of the times to be interpreted theologically in light of the living God who creates and redeems, this is it. Impacted by the Contours of the crisis, this book's dialogue between Darwin's view of evolution and Christian belief in the God of love has delivered us to a crossroads: the option for conversion to the Earth, or not. The option reaches into profound depths, for the call to be converted to compassionate care for other species is not in the first instance an ascetic or moral mandate, but an urgent invitation to be converted to God: to love in tune with God's abundant love so that all may have life.
— Elizabeth A. Johnson, Ask the Beasts: Darwin and the God of Love
