A combination picture shows the "Puente Nuevo" (New Bridge) in the day (top), illuminated by artistic lights (C), both before the Earth Hour, and during the Earth Hour (bottom) in Ronda, southern Spain, March 28, 2015. 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 action to confront climate change. The Puente Nuevo is 120 metres (390 feet) high and the gorge of the river divides the city of Ronda. REUTERS/Jon Nazca
