Be sure to unkill your television tonight so that you can watch Charles, Prince of Wales, discuss all things environmental in the documentary Harmony. No slouch when it comes to green issues -- Charles converted Duchy Home Farm to organic farming way back in 1986 -- the royal-green celeb takes viewers on a tour of his biggest issues, including climate change, green energy, and sustainable agriculture. There's even a 20-year-old clip of Prince Charles discussing the need for greater international cooperation with our own ahead-of-his-time eco-visionary, Al Gore.
Harmony airs on NBC at 10 p.m., following an hour-long interview with anchor Brian Williams that covers more mundane topics like the prince's marriages and the upcoming nuptials of his son William.
