Celebrate Earth Hour 2014

On March 29th at 8.30 p.m. local time, hundreds of homes, offices, and famous landmarks across the world turned off their lights and remained in the dark for a full hour.

This celebration was launched in Australia by green group the World Wildlife Fund back in 2007 and it has since become the world’s biggest and most popular environmental event.

According to reports, 7,000 cities took part in the event last year, and the WWF’s (World Wildlife Fund) website says this year the lights were cut at famous landmarks such as the Empire State Building in New York City and the Space Needle in Seattle.
