# Key Lessons and Hopeful Examples

1. Connectivity: Cities need a continuous fabric of walkable, multi-modal streets and public spaces — and structures that support it.

2. Diverse opportunity: “Cities for all” are necessary not only for justice — they are necessary to how well a city actually performs.

3. Adaptation:We need to harness the power of evolution and adaptive morphogenesis, using it to generate forms that can more successfully accommodate human needs, activities and experiences.

4. Environmental sustainability: Cities offer us very powerful ecological and resource benefits — but we need to understand and empower their network dynamics.

5. Systems Reform: If we want better cities and towns, we need to change the “operating system for growth.”
