It has been said that "earth hour" started with an idea, then a symbol and finally it was hatched into a movement to appeal to the inhabitants of the world to be united in protecting the earth.
"Earth Hour" is conceptualized to help the planet earth and a lot more benefits so to speak when conscientiously observed. So be it.
Anyway, we've observed it. At the strike of 8:30 p.m. our youngest son took hold right away of our electrical main switch and switches it off. Our two grandchildren, Bryan, 9 and Adgel, 8 were surprised why the light went off.
