This Saturday March.19th between 8:30pm-9:30pm the world will celebrate Earth Hour.  For 60 minutes, millions of people in over seven thousand cities and 172 countries across the globe will turn off their lights to support climate change awareness.

40 UNESCO world heritage sites went dark last year, so did  the Eiffel Tower, and in Vancouver, City Hall and the public library also went dark.  Will you?

 

 

 

As well as turning off your lights for one hour, you can also join the Earth Hour challenge by using your social media power and the #ChangeClimateChange hashtag, and/or change your profile picture on Facebook.
