James Gamble, of Proctor & Gamble released this feature-length documentary last week and it went viral almost instantly. I cannot do enough to recommend this video to you. In the beginning you may think 'this is bunk, I'm done here," but please, please, PLEASE watch the whole thing.
Ironically, I started a thread on many of the same topics covered in this video, just before seing it. You can check it out here, although Gamble's video is broader in scope, and obviously has much better funding and research than I could manage on my own. I will say there are some specifics in my thread that suppliment the Thrive video nicely, and that it specializes in discussing some things that he could only mention breifly, so please come check it out at your leisure.
