Have you made a plan yet for Earth Hour? It's coming up tonight between 8:30 and 9:30.
Again this year, more than 680 employees of the City of Saint John are taking part in the global movement to raise awareness of the overuse of energy in modern society.
In the past, major landmarks around the world have gone dark to bring attention to Earth Hour. The first Earth Hour was celebrated in Sydney Australia on March 31st 2007 involving 2.2 million people.
It has since grown to include 7000 cities and 152 countries.
