START THINKING OF EARTH HOUR
Turn off as many lights as possible
We know turning out the lights for an hour might seem a little pointless since it won’t actually affect noticeably on saving the planet. However, it does make a difference as a powerful statement, raising awareness and lasting far longer than 60 minutes. Based on this I made this Game called “Turn Off Light!” to make this event more fun and enjoyable.
