Hey there! The annual TreeHugger Person of the Year vote is underway (Voting ends Thursday!) and we thought it'd be fun to do a live video chat about this year's nominees, why they were selected, who didn't make the cut and why and what all this means for the environmental movement. We'll also plan to answer a few questions from readers. We'll get started at 3pm EDT today, so come back to this page later and click play on the video above to join the show.
