We thought we were done with Arianna Huffington for the day, but then Willow Bay, Huff Po's senior editor in charge of "non-political content" returned our call and we just had to discuss today's announcement of HuffPost Green, a new addition to The Huffington Post done in partnership with TreeHugger and Planet Green.

The site, which those of you who click on the link above will notice, is not yet live (June 4 is the official launch) so we inquired as to why the announcement came today. "I don't know," Bay said. "Part of it was to preview, but there's no reason it was specifically today." So much for our hopes of a diabolical PR campaign.

HuffPost Green "will focus on eco news and trends — from style and eco-conscious celebrities to green lifestyle tips and the latest scientific findings and expert analysis," according to a release. "Environmental issues have always been in Huff Po's DNA," Bay said to explain why breaking the content into its own vertical made sense.

The area will function similarly to the site's other verticals such as politics, media, business, living and entertainment, and have its own, currently unnamed, editor who will start next week. The Huffington Post's environmental columnist Olivia Zaleski will play a role in curating content, as well. Bloggers from TreeHugger, Planet Green and The Huffington Post will round out the content and Bay says she is recruiting writers.

It always seemed to us that Arianna launched the politically minded HuffPo at the perfect time and it wouldn't surprise us if we were saying the same thing about this section a year or three down the road.

Full release after the jump.
