Sustainability, as put forth in the Brutland Commission’s landmark report, Our Common Future, imposes “limits to growth” to ensure development “meets the needs of the present without compromising the ability of future generations to meet their own needs.” Grounded in urban planning, sustainability took root nearly a century ago in a set of regional plans John Nolen and Lewis Mumford put forth to limit growth and strike a balance between ecological relations and consumer demand. If their works were Utopian, they were also culled from the study of nature and history and they left a timeless legacy.

乌托邦现代世界计划

正如Brutland委员会具有里程碑意义的报告《我们的共同未来》所提出的那样，可持续性强加了“增长的极限”，以确保发展“满足当前的需求而又不损害子孙后代满足其自身需求的能力”。可持续发展植根于城市规划，将近一个世纪前在一系列旨在限制增长并在生态关系和消费者需求之间取得平衡的区域规划中扎根。如果他们的作品是乌托邦式的，那么他们也是从对自然和历史的研究中被淘汰出来的，留下了永恒的遗产。
