Earth Hour, organized by the World Wide Fund for Nature, an international NGO, states its mission is “uniting people to protect the planet.”

Other local landmarks participating included The Getty Center, L.A. Live, the L.A. Convention Center, Shrine Auditorium, The Fonda Theatre and the STAPLES Center, according to WWF.

L.A. Mayor Eric Garcetti earlier said City Hall would also be participating.

“Climate change is at our doorstep, and unless we take action now, we  face dire environmental and economic consequences,” he said.
