It's Earth Day! I know, every day should be Earth Day, but this is still an opportune time to highlight some of the great eco-diarists on Daily Kos.
With that in mind:
Welcome to the official Earth Day @ DKos Blogathon Mothership diary. I will keep an updated table with links to eco-diaries beneath the fold. Feel free to treat this as an Earth Day open thread, and pimp any diaries that I may have missed.
I have also compiled some good, bad, and ugly environmental factoids that caught my eye. I hope they give some insight into the ecological dangers we still face on our Pale Blue Dot this Earth Day, in 2010.
This diary is part of the Earth Day @ DKos Blogathon! Many excellent diaries have already been posted, with more to come:

Be sure to drop by for some top-notch eco-writing and planet-friendly discussion. Have a happy Earth Day!
Recent Gallup polls found that Americans are growing less concerned about some major green issues and more optimistic about 'environmental quality' (whatever that means) in the US. To be fair, things are getting better under the Obama administration, but the numbers don't lie. We still have a long way to go...
