Summers show in Chapter 6, path dependencies in cities maintain legacies of inequality and turbulence, while also limiting opportunities for innovative and comprehensive solutions.Path dependency is particularly problematic because it bolsters institutionssuch as states, sovereignty, transnational corporations, and markets-that are degrading, disrupting, and destabilizing ecosystems (Dryzek 2016). Susan Park exposes these consequences in Chapter 9, revealing how state strategies to reduce the risks of "disasters" are contributing to planetary turbulence by treating the sovereign state system as separate from the global environment, and by externalizing the risks and costs of global competition for natural resources. This short-term thinking and myopic approach, as she says, is not only leaving states ill-equipped to solve escalating global environmental crises, but also aggravating global turbulence.
