When we talk about sustainability, we tend to look at the big picture. In this TED Talk, futurist Alex Steffen explains that the real change will come from cities. He argues that collaborative consumption, neighborhood-based green initiatives and city planning policies that reduce car usage will lead the way to a more sustainable future. While many of these ideas will be familiar to our regular readers, Steffen presents an inspiring vision of how shareable cities can transform the world.
