After the Deluge
In this book, sea level rise leads to a smaller San Francisco in the year 2445, where all food needs are met by the city. The bay teems with life, and people eat Cioppino everyday. Most travel is done by bicycle, and streets have been turned into gardens.
As I read, I've been wondering about the population, how much lower, or higher than present SF is it? Most of the city is turned to the plow, but people live in group homes, which makes it hard to determine population.
