"Imagine the cityscape of the future. Forget skyscrapers studded with undimmed lights. Instead, think of crystal whites and luminous blues forging the city’s silhouette. Picture a city that sucks in carbon and uses bacteria harvested from dead fish to light the darkness. The city as a living character will no longer be a literary conceit, but a reality. From metaphor to concrete in one generation."
