In response to new environmental pressures, nature adapts rapidly, often within several generations. We humans now find ourselves in a similar predicament. Confronted by a changing environment, we also must adapt, and we must do so quickly in order to achieve carbon neutrality by the year 2030. Those of us committed to changing the business-as-usual aspect of the industry must define a new species of building, one that operates at a scale large enough to affect real change. We are Team 2020—ecohome-reading, LEED AP-ing, GreenSpec-toting, xeriscaping, carbon-sequestering Biomimiacs—and we must act now.
