Moms and Dad are pawticipating in Earth Hour again this year. We've all helped, since 2008. Earth Hour is sponsored by the World Wildlife Fund. It's simple to pawticipate. You just need to get your two leggers to turn off the lights at 8:30 p.m. local time for an hour. That will really save the world a lot of energy!! There is a city in each state that is pawticipating too! Nashville, TN is our closest city. They are going to shine green lights on the skyscrappers downtown, before the lights go out!! KEWL!
