'Earth Hour' to be observed today at 8:30 PM
The World Wildlife Fund for Nature is organising the twelfth annual 'Earth Hour' on Saturday from 8:30 to 9:30 PM local time. The worldwide event encourages individuals to turn off non-essential lights for one hour as a symbol of their commitment to the planet. First held in Sydney, Australia in 2007, the lights-off event reached record 178 countries in 2016.
