When Is Earth Hour?
Earth Hour is held on the last Saturday of March each year, usually from 8:30 p.m. to 9:30 p.m. local time.
What Is Earth Hour?
Earth Hour started in 2007 in Sydney, Australia when 2.2 million homes and businesses turned their lights off for one hour to make their stand against climate change.
Only a year later and Earth Hour had become a global conservation movement with more than 50 million people across 190 countries and territories participating. The numbers have increased every year!
Global landmarks such as the, Sydney Harbour Bridge, The CN Tower in Toronto, The Golden Gate Bridge in San Francisco, and Rome’s Colosseum, all stood in darkness, as symbols of hope for a cause that grows more urgent by the hour.
But Earth Hour is just the beginning.
If we all make a small change, we can make a BIG difference!
Here’s how you can help!
Turn off lights when leaving the room
Turn off computer at night
Take short showers
Walk or bike if you can (instead of driving)
Unplug appliances you are not using, like the toaster or hair dryer
Avoid electronics for 1 hour a week
