Almost every day on Live at 4:00, we ask you to send in a question of the day, maybe about a story we've been reporting on.

Then, we try to get the answers for you.

This time, we have a question that's actually more of a comment...

Sharon wondered if we will encourage people to participate in Earth Hour 2008.

Well, if you're like us, we wondered, what is Earth Hour?

So, here you go Sharon and anyone else who'd like to take part.

Earth Hour 2008 takes place March 29th at 8:00 p.m. For one hour, we're asked to turn off lights and non-essential electrical appliances.

It's an evening to promote electricity conservation.
