Absolutely INCREDIBLE documentary! I checked all the sources and they're all reliable and well designed studies. It's funny how there are a few articles on the internet that are trying to disqualify the stats in game changers, but I've looked into a bunch of the articles on the first page of google, and 100% of the article authors/ companies that have written them, benefit from the meat and dairy industry either through sponsoring or they profit off the meat & diary industry (ie. they've written cookbooks that feature meat & dairy) - they're ALL biased. Game Changers is not biased. Moral of the story, do your research into ALL parties who write articles and produce content on the internet.
Game Changers rocks and I've seen it like 5 times!!
