Arcology is a concept that combines architecture and ecology to create self-sustaining habitats. These structures are designed to house large populations while minimizing their environmental impact. By integrating living spaces, workplaces, and green areas, arcologies aim to reduce the need for transportation and promote a sustainable lifestyle. The idea of arcology was popularized by architect Paolo Soleri, who envisioned these massive, vertical cities as a solution to urban sprawl and resource depletion. Arcologies often feature renewable energy sources, efficient waste management systems, and green spaces, making them a model for future urban development.
