It's not just Earth Week, it's National Parks Week, and one of our fave TV stars ever, Lost's Josh Holloway (a self-proclaimed nature nut), is joining forces with the National Parks Conservation Association and sponsor Nature Valley to protect the U.S.'s 58 storied national parks. Press play above to hear more about Holloway's work to restore Joshua Tree in California and protect desert tortoise habitats. As the star says, "To actually volunteer and get involved means a lot, and brings it home." Plus, find out why the Mission: Impossible 4 star cut his hair short after the end of Lost!
