Arcology is a concept that combines architecture and ecology to create self-sustaining habitats. These structures are designed to minimize land use while maximizing space for living, working, and recreation. By integrating nature into urban environments, arcologies aim to reduce pollution and resource consumption. The idea of arcology was popularized by architect Paolo Soleri, who envisioned large, densely populated buildings that could support entire communities. These designs often include green spaces, renewable energy sources, and efficient waste management systems, promoting a harmonious relationship between humans and the environment.
