If you are into movies with a survival-type theme, let me suggest Heatstroke (2014). I watched it recently because one of the stars is Maisie Williams, who you might know from Game of Thrones or, more recently, her appearances on Doctor Who. It was surprisingly good. The story, without giving away any spoilers, is two women are lost in the desert grasslands of southern Africa, battling nature (predators, snakes, scorpions, brutal heat, lack of water), while trying to avoid/escape from some real bad guys. The movie does start off a bit slow with family drama (teenage girl angry with her divorced parents and her dad's girlfriend, who she blames for the divorce). But after about 15 minutes or so, it finally gets to the action and gets much, much better.
I've also recently watched, and was quite impressed by, the Back to Eden documentary. Here's the blurb from their website: "Back to Eden Film shares the story of one man’s lifelong journey, walking with God and learning how to get back to the simple, productive organic gardening methods of sustainable provision that were given to man in the garden of Eden. The food growing system that has resulted from Paul Gautschi’s incredible experiences has garnered the interest of visitors from around the world. Never, until now, have Paul’s organic gardening methods been documented and shared like this!" You can watch it for free on their website if you give them your email address. It is also available on You Tube.
The two hour documentary, In Defense of Food, recently aired on my local PBS station (check listings in your area). It is based on Michael Pollan's book by the same name. It is a fantastic review of what has gone wrong with the Western diet, leading to all sorts of health problems (way too much sugar, too many unpronounceable non-food ingredients, reliance on incomplete & changing science, false marketing claims, etc.). Pollan's advice is summed up in his motto: "Eat food. Not too much. Mostly plants." I don't agree with everything Pollan says, but I do agree with most of it. It is definitely worth watching, and will be very eye-opening, in many different ways. HIGHLY RECOMMENDED.
