Earth Hour is a global campaign, held and supported by WWF. The main goals were to raise awareness about climate change and to get homes and businesses to reduce electricity use and turn off non-essential lights for one hour, on March 31 2008 (8-9pm). Light Switch Stickers were strategically placed all over city streets and public spaces: walls, lampposts etc. The stickers were always placed at a height where one would normally find a light switch but on places where you never find one. The Light Switch Sticker’s layout was so real that passersby, just to double check, would often press it.
