We stand at a crossroads. Cities must change radically to achieve long-term sustainability. Energy, food and water sources, transportation systems and basic infrastructure, must all adapt to emerging pressures from climate change, dwindling resources and growing urban populations.
How will we meet this immense challenge? In a program that is part celebration of human ingenuity and part stark reminder of the problems we face, urban planner Peter Head, architects Blaine Brownell and Mitchell Joachim, environmentalist Majora Carter, and microbiologist Dickson Despommier laid out radical blueprints and innovative solutions as they imagine housing, feeding, transporting and sustaining city dwellers of the not too distant future. The event was moderated by President of the Aspen Institute and noted journalist, Walter Isaacson.
