Lost Waters. Before Venice, Tenochtitlan existed as canals and in the 1870s so was Mexico City. Pictured here is the Canal de Santa Anita or La Viga in what is now downtown in the Mexican capital, Citizens and villagers traded maize, sugar, vegetables, flowers and other products, still practised today. However, today the surface waters are 98% gone. All the rivers that fed these canals once from the hills in the Valley of Mexico are either gone, direly polluted or and then transformed into underground sewage canals flowing all across the city.
