Book excerpt: This is Hope compares the outcomes of two human ecologies; one is tragic, the other is full of promise. As Will explains in his Introduction, ‘Our human ecology is the expression of everything we do and is represented by every interaction we have on earth…it consists of the multitude of relationships we have with other people, other species, and our physical environment’. He describes our current human ecology in depth to illustrate how we are living inappropriately, cruelly, and unsustainably. This is obsolete and has been for a long time; it is the cause of our overpopulation, our overconsumption of resources, the poverty of ecosystems and people, and our disregard for the rights of individuals from other species. This is Hope proposes a new human ecology to replace it.
