Jesus of Nazareth said “If you have faith the size of a mustard seed you can say to this mountain: ‘Move from here to there,’ and it will move.”  Wall Kimmerer’s “mustard seed” is The Serviceberry (shadbush). From this tiny example, the author reflects on the massive movement that we can and must undertake to turn around the human trajectory towards extinction. In a small but sweeping manifesto, she invites readers to pursue community development through a “Gift Economy” that needn’t be a utopian theory but can very well be built alongside and in opposition to the “Market Economy/Mixed Economy” that is accelerating climate change and leaving us with feelings of despair and isolation in the process.
