Buses in the Uruguayan capital are providing a moving theatre for an environmental message, spreading the word about the value of potable water, biodiversity, and promoting active participation in environmental affairs. “Passenger Theatre” is an initiative launched in 1999 by the local Polizonteatro theatrical group. It is financed by the United Nations Educational, Scientific and Cultural Organization, the UN Development Program, the Organization of American States and the Interamerican Development Bank.

The environmental theme is new to the program. In previous years, Polizonteatro has focused on cultural questions and specific issues of interest to local communities.
