Buildings produce nearly 40% of the world’s yearly carbon emissions. Emerging Ecologies: Architecture and the Rise of Environmentalism explores how architects in the US responded to the environmental crisis of the 1960s and 1970s, when concern with rising pollution and runaway resource use spurred widespread activism on behalf of the natural world. Tracing the innovative, fantastical, and daring projects that architects proposed as environmentalism gathered steam, Emerging Ecologies tells an alternate history of architecture that focuses on designers who have made the natural world a centerpiece of their practice.
