WaPo, LETTER FROM MEXICO CITY: An ancient paradise, cut adrift — Capital’s famed floating gardens, heritage of the Aztecs, are in ecological peril
A vendor poles a boat filled with marigolds. In Aztec times, the farms were irrigated by an immense grid of miles of shallow canals, just wide enough for a canoe. The gardens produced a bounty: five or six crops a year, an abundance of chiles, greens, cactus and herbs. The canals were also exploited for crayfish, frogs, fowl, and fish.
