The document describes a competition that challenged teams to imagine and design cities 100 years in the future based on principles of biomimicry and sustainability. Eight teams were given one week to design three different cities - New York, Washington D.C., and San Francisco - focusing on reimagining elements like transportation, neighborhoods, water and energy systems, and buildings in a way that mimics natural ecosystems. The goal was to move beyond traditional urban planning and design cities that are resilient, optimize resources, and live in harmony with the environment like a forest.
