Earth Hour is this Saturday. For those who don't know what that means, Earth Hour is just a wonderful opportunity for millions around the world to unite in a simple yet strong demand for action against climate change. And all you need to do is turn off your lights for an hour. This is Earth Hour's third year, and it keeps getting bigger annually. Last year, nearly a billion people flipped the switch in about 4,100 cities in over 86 countries. This is big. And this year it will be even better. What you can do is take part in it. Turn off your lights in your house, office, etc this Saturday, March 27th from 8:30 to 9:30 P.M. local time. Please REGISTER to do that here:  https://www.myearthhour.org/home If you want to do more, please SPREAD THE WORD by emailing your friends and updating your Twitters and Facebooks or whatever it is you do. Many people know about this but still many more could. Want to do even more? Great! By signing this you're sending an email to some talk show hosts asking them to talk about Earth Hour on their show! That'll get the word out. Thank you.
