As is the case with many documentaries, Blue Gold brings to light many hard to hear but prominent facts about the worlds water sources. It helps explain the cycle of water, or at least, how it's supposed to cycle around. And it delves into why the cycle is being disrupted, and how, and why it needs to be reversed.
One of the parts that struck me about it all is that we're pumping so much more groundwater then is being put back in, so the cycle is stopping, and draining some lakes and rivers until they're pushed to desertification. We've managed to cover most of the ground with cement, which successfully prevents water from soaking into the soil, and we've rerouted water with the use of dams to suit our needs. But is that necessarily a good thing? By doing all of this, our water supply is now dwindling, and some people in further out countries are even dying of dehydration, which is something that's hard to imagine.
Personally I feel that Blue Gold spent a lot of it's time going over the problem, and why it's a problem, and just generally making everything out as bad, and wrong, and why that is, rather then spending a larger portion of its time saying what we COULD do. Sure, at the end there was about five or ten minutes where it talked about how there was some research going on, and a few good things that were starting to happen, but really, the film only served to depress me more about how humans are destroying our planet. I feel like these documentaries need more time talking about the good things, and talking about uplifting things that are being done around the world.
