Earth Hour

Earth Hour is an annual event to promote reduced energy consumption for the planet Earth by turning off non-essential lights for one hour from 8:30 to 9:30 p.m. on the last Saturday in March. It was first organized by the World Wide Fund for Nature (WWF) as a lights-off event in Sydney, Australia in 2007. Since then, 7,000 cities, 1,200 landmarks and 172 countries and territories have joined the action to raise the awareness of climate change.

It features a quote from a Senegalese forestry engineer Baba Dioum: "In the end we will conserve only what we love. We will love only what we understand. We will understand only what we are taught." Sent before and received on Earth Day, April 22, 2012, it also highlighted the theme for Earth Day 2012: Mobilize the Earth.
