Well, by now I should know better than to worry about random videos on the internet, but this one in particular was very persuasive: There's No Tomorrow http://vimeo.com/36624246 The video is somewhat long (a little over half an hour), but it's worth a watch, at least for its entertainment value. The main theme of the film is: we're going to run out of oil (duh), and no, we're not ready for it. Not exactly big news, but what's a bit different (and much scarier) about this film, is that it then goes on to show how our current alternative sources of energy will just not cut it. Some of them actually rely on an initial investment of fossil fuels to actually work (apparently). There's not enough arable land for biofuels (plus our current cultivation techniques rely heavily on cheap fossil fuels), population is rising, solar panels require several barrels of oil to be made, our economies are tied to oil, etc. The bottom-line is that you should probably start building a barbwire fence around your home-grown vegetable garden. The problem with this video is that I don't know enough about the subject matter in order to judge its contents, and the fact that it's just there on the internet with comments disabled, makes it suspicious by default. What do you guys make of this, is the logic sound? Do the numbers add up? It could well be that this documentary was made as a marketing ploy to promote the company that made it, but it was so persuasive that a few months after I watched it I am still thinking about it.
