Got a burning green question Grist hasn’t answered yet? (Hard to believe, I know.) Think quick because you have until 3 PM Pacific today to send ’em in because our big brains — along with our friends’ at Huffington Post Green, Treehugger, Causecast, Chelsea Green, Earthtweet by Brighter Planet, Live Earth, and Worldchanging — will be answering them in a video montage for Earth Day. You have to submit your questions here via comment or video on (or to @current_green on Twitter), where they’ll be featured in said video package.

Besides getting your most dire eco-inquiry explained, it’s the perfect opportunity to kick off your reality TV career when the Q & A segment appears on the small screen on Current TV. Extra points if you submit your question in American Idol entry format.
