A combination photo shows the “Puente Nuevo” (New Bridge) in the day (top), at night (C) and during Earth Hour in Ronda, near Malaga March 23, 2013. Earth Hour, when everyone around the world is asked to turn off lights for an hour from 8.30 p.m. local time, is meant as a show of support for tougher actions to confront climate change.
