Environmental activist, attorney and best-selling author Robert F. Kennedy Jr. will speak at the Eccles Center for the Performing Arts on Dec. 9 in a program sponsored by Great Salt Lakekeeper and the Park City Performing Arts Foundation

One of Time magazine's "Heroes for the Planet," Kennedy has earned a reputation as a leading defender of the environment from his litany of legal actions, numerous publications and as chairman of the board of Waterkeeper Alliance, a collective of 150 Waterkeeper organizations worldwide, dedicated to protecting local waterways. He will speak about the important role our natural surroundings play in our work, health and identity as Americans.

The lecture at the Eccles Center, 1750 Kearns Blvd., Park City, on the campus of Park City High School, begins at 5:30 p.m. Tickets for the lecture are $18 and $30 and may be purchased by contacting the Eccles Center box office at 435-655-3114, or by e-mailing boxoffice@ecclescenter.org. The box office is open Monday-Friday from 9 a.m. to 4 p.m.

The speech is a benefit for Great Salt Lakekeeper, a locally based environmental conservation organization and licensed member of Waterkeeper Alliance.
