What can you do to make a positive difference for the environment during and after Earth Hour 2010?

It's 4 minutes left before I will log off my computer to join the earth hour cause. It makes me feel good to know that by just switching lights I can help save mother earth. I always make see to it that our household conserves water and energy. to the point that we sleep together in the masters bedroom along with my all 4 kids to use one conditioner at night. It is fun .. really and besides it makes us all closer because we talked... till our eyes shuts. It's a good bonding to sleep in one room. Really.
