Earth Hour is an annual event, however it is a campaign addressed for everybody who wants to be part in making this planet a safe place to live in.
Earth Hour only asks people to turn off the non-essential lights for one hour, not lights that affect public safety.
Earth Hour 2016 happened last Saturday, 19th March between 8.30PM and 9.30PM while I was at the Mall of Asia.
I witness how the establishment turned off their non-essential lights for one hour. Earth Hour is also a celebration of the planet so it’s important to enjoy the moment in a safe environment.
