- There is a virtual water market that is critical to the survival of our species. The problem is that most people are completely unaware of the concept, and the impact it has on “everything”.
Seth B. Darling is a scientist at Argonne National Laboratory and a Fellow at the Institute for Molecular Engineering at the University of Chicago. After receiving his Ph.D. from the University of Chicago in physical chemistry, he came to Argonne as the Glenn Seaborg Distinguished Postdoctoral Fellow in the Materials Science Division. Following his postdoc, Dr. Darling joined the Center for Nanoscale Materials at Argonne as a staff scientist. His group’s research is motivated by humankind’s grand challenges and centers around molecular engineering with a particular emphasis on solar energy and water treatment. Dr. Darling has published over 100 papers and a popular book on climate change, holds several patents, and lectures widely on topics related to energy, climate, and water.

Watching this in December 2020, right after Wallstreet anounced that it is now trading water. 🙃
Same. Anything else informative that you’ve watched?
this really moved me
This video is underrated!
Informative .
After Covid, Water Crisis will be the biggest challenge in front of us! Better start managing this precious resource.
Whatever we do, we have to not destroy the water cycle. It that thing is done, we are done.
just commenting to let you know were done for now that wallstreet is gonna start trading water as a commodity
@@Watamelen what? You don't understand how water futures work. It doesn't actually trade water. Its like water insurance. Your not going to accept delivery for gallons of water. This is for the big players who want to protect their water incase of a drought. They will buy water futures.
First question I had about water shortage was how can we have one whilst reusing it and cleaning it for reconsumption. Second questions is how can water be traded without a planned shortage of it? You don’t trade commodities without controlling them. I’ve heard advertisements of washing your dishes without water. Using a chemical scrub to clean them. How would that not leave residue? Hot water tends to rid our dishes of residue. Also, the advertisement said you use 4 gallons of water every minute to wash dishes. That’s a lie. I just filled 4 gallons of water and dumped it into my kitchen sink, which I will use to wash dishes but the amount is more than I would ever use to wash dishes. It took me 2:24 to fill 4 gallons of water and that is with starting and stopping the clock once the gallon was full. The sink is far more full than I need.
Mining in arid lands! - A great deal of water is used for physical and chemical processing of deposits. Milling of rock takes enormous amounts of electricity, which in turn requires a great deal more water. In areas such as the Southwest USA, there is only little nonrenewable water supply, and much of it is consumed by mining.
Thank you Seth your talk it is right, water scarcity is a real thing today and will get worse unless humans change right away the way we use it. More than 70% of the available fresh water is consumed by agriculture and food production must be increased many times to supply the growing population. So, if agriculture requires more fresh water there will be less water available to cities. The solution is that agriculture must be discarded as a human activity. Agriculture has been, and it is the single most devastating activity to earth's ecology. I propose hydroculture as an alternative. Hydroculture is the production of food without using soil and one of its most known activities is Hydroponics, Aeroponics, Aquaponics, etc. Let me explain some benefits. One acre of hydroponics vegetables produces the same amount of food as 10 acres in agriculture. Growth cycle is faster for instance it takes for agriculture 90 days to harvest lettuce with hydroponics production takes less than 60 days. Since there is no need for using soil hydroculture can be performed anywhere that is within cities, in desserts, arid lands, etc. No use of pesticides since production is controlled at least no herbicides. THE MOST IMPORTANT FACTOR IS THAT USES 90 to 95% LESS WATER THAN AGRICULTURE. So the impact is that cities will have more supply of fresh water with less pesticides. My name is Enrique Lulli, I live in Lima - Peru and I hope to receive some feedback. Many thanks.
As I write this comment, /20/2020 California’s Sustainable Groundwater Management Act (SGMA) is starting to be implemented. What was once the hidden environmental cost of groundwater over drafting will be adjusted in mainly agricultural products as water management is mandate by law, Michael Burry’s prediction of profits in virtual water. California is a trend setting state / economy - expect over the next few years other states and countries will follow, and the race starts on a virtual water financial market.
existe el vídeo en español? o subtitulado? / Is there a video in Spanish? or subtitled?
crazy.
I'm from Rajasthan, of which 60% is desert. I want to ask member of parliament from my area that how is he gonna raise this issue in the parliament... But unfortunately MP of our area doesn't even know care it.. I never heard or read him talking abt it.
Watching it b4 my semester exam 😂
Electricity 'contains' much virtual water. Any 'steam engine' type power plant, be it gas, coal, or nuclear powered requires cooling which is done almost always with evaporative cooling towers that consume a great deal of water. Unfortunately, electricity is not reusable, nor recyclable because it always turns into waste heat, so all that we can do is use it wisely. Save water - don't waste electricity.
No mention of Grand Solar Minimum and the impact on water cycle. Interesting omission
I don’t trust this guy’s mat
this guy is getting a lot wrong.
like what?
@@quinnmchugh1362
Firstly the gender politics about the women carrying the water.
He uses western ideals on a society that is completely different.
Just like when people use todays morals on yester years.
Secondly the usual vegan claptrap about meat, then talks about buying local, buying local whether it meat or veg will definitely cut down your footprint, unfortunately you can't just do the veg part, it will come with deficiencies, unlike animal produce.
Pastured animals rely mainly on the rainwater, plus the water from the grass, which is 85 percent.
Thirdly and finally, he uses the dinosaur urine as a comedic slot in his argument but totally ignores that ruminants do exactly the same thing.
Mother nature rarely get things wrong.
That was just in the last few minutes of the video since then is when I saw your comment.
this is 2016
u wasted My TIME
