The amount of garbage on the streets of downtown Macaé, in Brazil, dropped 60 percent thanks to the Eco-Citizen project that uses theater as its primary method for raising environmental awareness. Since September 1997, a team of eight actors and entertainers have worked to win the public's collaboration in reducing pollution, said Marielza Cunha Horta, the project's coordinator.

Since Eco-Citizen began its efforts, litter has also dropped 40 percent along the beaches of Macaé, a city of 200,000 people located 190 km from Rio de Janeiro.
