Ask the question. Save the planet?

So I've just kicked-off an email campaign that I hope will challenge people to ask the question, "What are you doing to help save the planet?"
I've sent it to all of my contacts along with what I'm doing in this regard with the hope that they forward it along to all of their contacts with a note about what they're doing and so on and so on...
What sparked me to do this was a story about new research (Minding the Eco-Gap) in a Contagious magazine newsletter - click on the Ask the question logo to read more. One of the insights "revealed that people ‘nudging’ each other was going to be key to changing consumer behaviour." Makes sense to me. We can't afford to wait for big business or government to solve the problem.
I hope that everyone I've emailed felt the same way and forwarded it to their friends and colleagues. But I suppose that even if one person did, it will have been worth the effort.
In any case, I'll post the result (ie. total number emails forwarded) in a months time.
