Brave Blue World: A Crise Hídrica

'It never ceases to amaze when the critics come out to play. I just can't figure out why they've zeroed in on a *positive* piece as this. It's astounding. I'd normally ignore yet I know for a fact - human nature dictates - there's hundreds of positive folk for each 'hater' (scientific or bias accuser) up here. Yes, I get that there's DuPont and others. I concur the big players are not playing well. Yet, we collectively must (must!) work towards the good stuff.

As far as I'm aware this is an optimistic look at the options. I commend the makers and I too am biased, I've known of this in the works for years. I am thrilled it's out there and moreover grateful, to cut-through the chat and get the new message to the new scientist who will over time weed out the institutionalized neg-heads. Sorry to sound crass or cruel, I don't mean to. But the gentle whiff of positivity needs to be encouraged and protected. Go make your own documentary and let me know and I'll support you all the way. Meantime, please treat this one as a 'asks the right questions' piece, that let's remember has really make it to the mainstream, as this has! A piece of work to inspire and hopefully to lead by! Congratulations!''

I recently watched this documentary with my family and kids over the weekend. I was eager to see what Matt Damon had to say about water!! All of my family enjoyed the film and learned something new including my 8 and 9 year old kids who have just informed me they would like to work in water!

The solutions presented were the right mix of science and story and the film really broke down some of the challenges in the water industry.

I hope there will be a Brave Blue part 2 or a series where they will go more into detail about each of the different areas within this complex industry.

(Beth's story was without doubt my favourite!)

This film tells us about inovative ways of conserving water, conjuring water where there is none and dealing with it once it becames waste.

I am a chemist, engineer, and water resource scientist. While I'm always happy to see a documentary raise awareness of water availability/quality issues, this documentary has a number of issues of its own.

First of all, the so-called 'solutions' being offered by its sprawling list of do-gooder celebrities are not innovative, novel, or sustainable. They're well-proven technologies putting temporary band-aids on deep sociopolitical problems for the sake of making their celebrity sponsors feel good.

Second, the film has a number of corporate sponsors. As a result, it failed to touch on some very real issues with the way we currently treat water. For example, Reverse Osmosis is disgustingly inefficient. It wastes about half the water it treats. It also absolute munches through power, and the waste stream from RO is a concentrated pollutant being shot back into the environment. But Suez, one of the sponsors, is a major player in RO and membrane desalination. So that got glossed over.

Third, it perpetuates the myth of a straight-up bogus technology. Humidity-condensers are not viable products. They've been debunked over and over and over again. The thermodynamics of converting whatever small amount of moisture is in the air to drinking water are enormous. And other than that lone instance of local innovation, the rest of the documentary reeks of western-savior complex.

This documentary is mental candy. Replaces real nutrition, and is bad for your teeth (from all the clenching).

Full of vaporware tech. It was painful to watch. So many contradictions between chapters. The odd chapters was interesting just to see existing industrial complex but mostly awful. And the narrative was just silly. How is this 7+ stars.
