Architect and educator Douglas MacLeod offers a stark and immediately compelling glimpse into the future,15 years hence, in which we can live and work together to build better communities for tomorrow. This insightful and intriguing book imagines the idea of cooperative communities where people can produce more energy than they use; purify more water than they pollute; grow more food than they consume; and recycle more waste than they produce, with technologies that already exist or that will be within our grasp in a few years. Most important of all, the people of the community own and profit from these resources. The Architecture of Hope depicts a way of living that is decentralized, re-localized, and regenerative. And possible. “Our communities are overpriced, poisonous, overcrowded, unhealthy, wasteful energy pigs – not because they have to be but because it suits the vested interests that build, operate, and control them ...” Strong words spoken by a character in The Architecture of Hope, Douglas MacLeod’s striking glimpse into the near future. And yet this is not, at its core, a work of fiction. So often the future we imagine is bleak. The environment, the quality of social engagement and cross-cultural relations, food security, education, work ... so much seems in decline. And, in fact, the future will be bleak, if we don’t change our ways of thinking. As one of the characters notes, “The big idea is that we could restore rather than destroy; we could produce rather than consume; and we could purify rather than pollute – not just the Earth but our bodies and minds as well.” While this scenario describes how we can use new technologies to achieve these goals, it emphasizes that, most of all, we need to change our thinking. It’s not that our communities can give us hope directly, but they can provide a scaffolding so that we can create full, meaningful and hopeful lives for ourselves, our families, and our neighbours.
