Welcome to the Earth Hour global community!

This coming Tuesday, April 24 (3PM PDT/6PM EDT) make sure you tune to watch a live discussion on Facebook Live Talks Earth Hour Co-Founder and Executive Director Andy Ridley.

What''s next for Earth Hour in 2012? How does the movement use social and digital media to inspire millions every year to share their commitment to the planet? And where is Earth Hour in its journey to create an interconnected global community sharing the resources and challenges for the environment?

Andy will be speaking with Facebook's Marcy Lynn about how the movement encourages millions around the world to power down for one hour each year, and the challenge of turning that small action into a year-around commitment to protect the planet. He'll also take questions directly from people on Facebook.

To submit a question to Andy, simply post it on the Event Wall on Facebook. Don't forget to join us at and join us at on April 24 to see if your question is answered. The live stream will last 30 minutes. If you can't tune in, check back to the Green on Facebook Page to watch clips from the event.
