Saturday evening at 8pm, all types of people speaking all types of languages, all over the world will join in World Wildlife Fund's Earth Hour.
What is it? Well, at 8pm local time on Saturday nite, participants will shut off their lights for one hour. What will you do? I don't know about you but I've got something romantic in mind. No partner? No worries, you can always spend the time changing out all those old lightbulbs to energy efficient compact flourescents. I've had one in my outdoor front light now that hasn't burned out in three years!
