"After WWII, the United States, which has been the wealthiest country in history, devoted most of its resources to building an environment that is unsustainable.

Suburbs created with roads and automobiles became too dense to be walkable and obstructed the meaningful destinations between cities and neighborhoods by use of public transportation. Now, its budget far exceeds its inner mechanics. It's time for the ecological city.

Not just "green spaces", but also introducing the discourse for urban planning. Social ecologists need to become involved in planning commissions with proposals for developments which emphasize dense cities, the reconstructions of viable neighborhoods, and public transportation."
