Monday was Earth Day, and Santiago observed the holiday with a big March for the recovery of Chile's water. Water has been privately owned here for 32 years, and people all over the country are living with the consequences. About 87 groups from all over the country were present at the march.
For more info on the movement, read this article that I wrote last week for Revolver Magazine: http://www.santiagomagazine.cl/special-events/00931-flowing-towards-la-moneda-earth-day-march-water-rights
