- Utah State University has flown more experiments in space than any other university in the world. Thirty years ago Bruce Bugbee and his students began working with scientists on a NASA-funded project to develop a life-support system for people traveling away from our planet. This task requires a recycling system that produces food from waste and keeps carbon dioxide, oxygen, and water in perfect balance. This project led Bugbee to appreciate the elegance of Earth's biological systems where plants recycle gasses, purify water, and provide food. Humans are increasingly aware of the impact of fossil fuels on climate change but overlook the impact of limited water on their ability to grow food. Bugbee and his talented colleagues have sought to improve water use efficiency in agriculture. He presents an analysis on the enormous water requirement for food production, reviews the crisis in world water supply, and shows how small changes in diet can have a major impact on our global food-print.
Bruce Bugbee teaches Crop Physiology and Plant Nutrition at Utah State University where he was awarded the Graduate Mentor of the Year award in 2001, the Researcher of the Year award for the College of Agriculture in 2005, and the Governor's Medal for Science and Technology in 2012. Bugbee is a past Chairman of the Crop Physiology division of the American Society of Agronomy. NASA has funded much of his research on the physiology of plants in the controlled environments of space. Bugbee has presented at several Universities as well as conferences in Europe, Australia, New Zealand, China, and Brazil and has authored or co-authored over 100 journal articles and book chapters.
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
This is my new favorite ted talk. I've been a huge fan of this man for years. He has a real talent in explaining complex subjects in a way that's easy to follow .
i absolutely love Dr. Bruce Bugbee´s talks
Flint Lockwood: *My goals are beyond your understanding*
Nice. Bruce even combed his hair for this one. Big fan of Dr. Bugbee! Thanks for all the wonderful info.
Seriously haha I’ve watched all his videos about growing cannabis and I said that to myself that he looks really cleaned up lol
AT MEXICO CITY( TENOCHTITLAN) AZTECS USED TO GROW PLANTS AT CHINAMPAS, WATER, SEEDS AND FISHES ....HUNDRED YEARS AGO....AT THIS TIME IS EASY TO WATCH PEOPLE USING CHINAMPAS AT VALLE DE MEXICO.....
Thank you! Education is KEY to success!
i just found this one, but ive been following all your medical hemp/cannabis classes and as someone who is plant based .. hearing you mention our foodprint and eating less meat. almost brought a tear to my eye. and to think that was in 2013.
We know the assignment, but just won't. Wtf is wrong with us? Do we deserve to be extinct?
Thank you sir for all you're doin!
GOD BLESS.
greenhouses use 98% less water than open fields. they can be CO2 enriched to speed up growth. they also don't waste any fertilizers which might go into aquifers, or destroy soil biota.
That's how it's done in the desert.
🧢
What about water wasted on golf fields, swimming pools, aquatic parks... ? What about destroying some crops to keep high their prices meanwhile starvation threats some people?
No golf court is ok, you can swim with the fish do, some culture grows fish at the same time, and other aquatic foods like kale spirulina, shrimp , trouts etc.This guy is a moron..
We got a lot to learn from older countries..
it is good to know far better to do what is right!
Thank you Bruce, great lecture!
excellent lecture thanks very much
Some of these people do such a great job! This man included.
This guy aint a farmer....
Green eyes he’s a scientist, on the forefront are scientists developing the new technology both you and the farmers use and tinker
Maybe not. But he is responsible for growing food on Mars….
Great Video! Long Story short and - explained easy so everyone can understand.
I really like him he has an amazing knowledge about plants and Environment!
He also works together with NASA in Research for about 30 years, i think is what he Mentioned. He really knows what He's talking about.
Very very very interesting, thanks !
Love this! Truth condensed. How eloquent! God Bless you!
Excellent demonstration 👌
I will be sharing this with my boy scouts and home-school students. Thanks Dr. Bugbee!
Not for farmers..
The real problem is the design of our houses. We must keep our foundations moist or the houses crumble. Also, the city-slickers have to have manicured lawns - wasting tons of water. Why? Why do we do this?
Agree. Everyone should just plant clover into their lawns and let it be!

This video needs more views!
"This is the diet for a small planet." No more 80-minute-shower hamburgers for this citizen of the earth!
Top bloke,
Increasing concentrations of Co2 reduces the number of stemata each leaf produces making plants grown in higher Co2 environments require dramatically less water. The need less water, they use less water and are more resistant to drought. I
The purpose of adding C02 is to increase plant growth by taking advantage of all 2000 or 1500 micro moles of photons per day of light where as without c02 you can only utilize about 900 micro moles of photons. With added light comes the need for added water and nutrients to drive the plant hard to reach maturity faster with higher yields.
He read a study and over estimated the height of those mountains.
From computer chips to agriculture..Nasa has really led incredible innovations
As a farmhand it really bothers me how much water farmers waste they water the roads ffs
Good lecture
We use much more water behind the scenes. For instance, 50 gallons of water to make 1 can of soup.
Those positions of ancient water wells have been known to feed Forrest and spring's.
1:50 Type it into any search engine, there are 3 times more water inside the earth as in all the Earth's Oceans.
Bro thinks he’s flint lockwood
Should be in school education ,great great informative lucture ,love hwo he made it intertaning,awesome guy thanks
Good enough for school d'information not enough for farmers..
Your cool buddy. 👍👍
I like some of his studies about light for food but here someone have to tell that Utah professor that we could grow food in salt water, which is most abundant material on our planet.
Stopped eating meat a year ago for this reason.
Yes, I encourage people to check out the documentary Cowspiracy which discusses the impact of methane on our environment. Meat wastes water and pollutes the environment.
And the Cambridge Declaration of Consciousness, July 2012, top Neuroscientists from all over the world combined statement: non-human animals are sentient beings, as their neurosynaptic systems are proven
How about the vital minerals that would only be found in soil
Turns out they aren't as vital as you think
So should we eat salt water fish?
There's so much food in salt water :) he's from Utah thou so not aware of that simple fact.
Makes sense to me.
Dr. Bruce, ballin in those sneakers.
He's trying to tell us to move agriculture into hydroponics.
So, that means the plant has more water within than carbon dioxide to absorbs, so the water within will sustain the plant, until the CO2 will come which is very low relative, so take a long time, so the water that is a lot is necessary more than human since the oxygen in compare to CO2 is higher so our need of water is less than the plant. So, water is the sustainer, but not the growth which come from other process materials. Like certain gas, certain solid, etc. Water can make you grow, but other materials make you grow faster. So, there is balance of gas / solid and liquid. Gas is tiny solid that we can't see and float in relative what we can see and stand on the ground. It is relative amount of liquid, solid, and gases.
They're gonna pry that T-bone right outta your chops.
We live on a water world --- water is not scarce. If you want more fresh water, then devote resources to desalination via evaporation using passive solar powered systems. Curious if this guy received any grants from groups connected to the sale of water futures.
Kevin Costner agrees
flynt lockwood?
We can generate electricity without fuel or pollution. We could generate electricity with Edison generators and dynamos without fuel or pollution. This is free electric power without fuel or wind or pollution. We can use the electric power without fuel to desalinate seawater with very little cost. We can recycle water and desalinate seawater. The aquifers should be preserved for emergency only. We should stop all well injection everywhere.
I like his logic. However, I might have done more than just suggest eating more fruits and vegetables. I might have suggested that we turn our eyes to better water conservation on the 30% side or fresh water production to replace the aquifers. Maybe we could ship it from Greenland? Or get back the amount we and the plants are breathing out? LOL. Come on people, let's get that ingenuity cracking. Maybe he needs to see the Tedtalk - Drawing water out of air?
Also the halt to adding sodium fluoride/hydrofluosilicic acid in most drinking water [American], etc.
What we add to any water source eventually has potential to contaminate other reserves/sources.
It's not logic. He learned a scip givien to him...He is not a farmer..
@@aebniala This guy is president of Apogy Instruments and professor at Utah state with a grow lab funded in part by Nasa. He knows what goes into to a plant and what comes out, he would give advice to farmers if they asked on any topic you could imagine.
@@anthonyromano8565 yep, he just did a wicked podcast with Chris over at Garden talk and is pretty active in the growing community on CZcams if you haven't seen it I would check it out
@@doctorprocter4225 i was surprised Mr Grow it could get such high faluting guests but then realized he is a student at Utah.
before O2 was high % and Co2 was not low, did plants have less stoma in fossil record?
Plants been much bigger.
Also CO2 super saturated water?
Possible to get extra CO2 into plant through root system?
Anybody try this or research done yet?
As far as I know adding carbons (CO2) drastically drops the pH of the medium and water itself. Just like acid rain from CO2 pollution
Much of the additional space needed for animal products is due to our methods of farming animals and the kinds of animal products we eat. Eating the animal destroys the source of the food, requiring replacement. While eating eggs and cheese doesn't. Additionally, crops can be raised on the same land as many of the animals, especially the small ones. Chickens fertilize and keep bugs at bay. Rather than trying to figure out how to feed an out of control population, maybe we should focus more on limiting human reproduction.
Now this is a good reason to be vegetarian, I'll try to eat less meat and more veg,thanks professor
Unlimited light unlimited water and unlimited electric power from Edison generators and dynamos.
We can produce unlimited electric power and unlimited fresh water if we improve the power systems with Edison generators and dynamos to generate electricity.
“ God Bless a You”
Oy vey
turn sunlight into food. God did that years ago ;)
at 2 minutes, we know why Orange baby man president wants to buy Greenland?
Wait we can't distill salt out of water????
Yes you can..Thermal distillation involves heat: Boiling water turns it into vapor-leaving the salt behind-that is collected and condensed back into water by cooling it down. The most common type of membrane separation is called reverse osmosis.
So all the salt water is permanently locked in and does not participate in the evaporation/precipitation cycle and can therefore be excluded from consideration? Seems a bit of a simplification of a complex process for a predetermined conclusion.
Watch it ONCE more. Right at the beginning of the water cycle review section, say, from the 5:30 mark on?
Your poor space travelers not only have to forget about getting real dairy products and animal protein to eat, they have to forget about pets, or even microorganisms, don't they? No livestock, no wildlife? You show this green area in your bubble house, but it doesn't seem like you're using any dirt on the spaceship... just hydroponics. So our priorities are different, bc I want to save the Earth, not fly away from it. The Earth can be saved with Permaculture land management. Grasslands can be restored with multi-species pasture cropping and intensive rotational grazing of livestock. The same plants and animals that once denuded the land are the answer to how to fix the land, if we use them in the proper way. We also need to stop looking at weeds and insects as problems to fix. I get that insects might be a problem on your spaceship, but here they are necessary to feed the birds. Many weeds are edible and medicinal, and their roots are good for the SOIL.
You cant use hydroponic you need gravety or the water goes every where. It logis as no logic. Earth is a spaceship..
why cant we make the salt water so we can drink it. that is the perfect solution for the needed for all to drimk
It takes an enormous amount of energy to do it.
There are plant that grow near salt water..
What the actual ****? I thought the guy was going to present us with means to accelerate food production,not just make an entire lecture and then toss a phrase "don't toss food you don't eat".
He has answered your question: go hydroponics. But as accelerated as it is you need the same amount of water for these types of farms too.
The main point is that we are depleting our water and energy resources for food. If we got as efficient as it gets towards water and energy consumption in cultivating then the logical step is to cut back on foods that use more water and energy for the same amount of food calories by lowering our meat intake. Think of Mediterranean diet.
He did not answer any question. He just threw out some stupid comment at the end and walked off the stage. What is wrong with this guy?
So, if we doubled the amount of carbon dioxide in the air, the plants would cut down on transpiration loss because their stomatophores would be open less often, thus reducing water loss..
Then the global warming people have it all wrong. We all need bigger carbon footprints to save the water supply. I hope President Trump sees this video.
I hope natural selection takes care of you.
@@sonja5611 Evolution isn't real. It is false religion. Your hatred doesn't disprove the point that was made.
Eat less meat, yeah, right. This is not biblically based. The vegetarian can't say to not eat meat and the meat eater can't say eat meat.
So in other words, vegetarians and vegans are the ones who are using much-less water and much-less farmlands, while meat-eaters, who are still representing the majority of the population are the ones who are keep putting a big demand for meat production, and as a consequence: more water use and more land being dedicated for agricultural animal feeds.
But what is the solution? Meat-eaters won't even stand to listen to the idea that their eating style/habits are causing such a big problem in our world. Meat-eaters say: "I live only once, and so, I deserve to enjoy my meals, -if I have to eat meat-less meals, then I rather want to die than eat that cardboard-tasting shit".
And while there are still big-enough demand for "meat", the meat-companies will keep on producing as much meat as much is being demanded by the market. And the governments all around the world are protecting the meat industry. So who's going to stop this reoccurring meat demand? And when? And how exactly?
While the number of people who becomes vegans each year are gradually/slowly rising, so does the number of meat-eaters rising, too, all around the world. The fact is, that most humans are still holding in their minds an "ideal"image of a meal, which (according to them) must contain meat in it to be acceptable by them or else they feel that they are being cheated and being denied their God-given human rights to eat whatever they want to eat.
If you want to make a "better"-difference, not just in the world but also for your own health (not to mention to stop animal cruelty), then go vegan, or at least become vegetarian!
George Galamb Bravo! Very well said! 👏🌱🌏✨
@ROBERT ANDERSON He is not a scientist, he is a politician.
It all depends on awareness and the consciousness levels of each fragment unit.
One cannot be forced to look within - one has to learn about the cause and effect from ones actions [karma means action] It is all an inside job, and, unfortunately, most in this age/yuga cycle are still self-centered and self-satisfactions/tastebud oriented - instead of other and all sentient beings oriented.
But vegans still participate in the agricultural water use via manure from farmed cows used to grow their produce also only 0.1 to 1. % of the world is vegan that's why they use so little
How about we start with maybe reducing the amount of meat we eat by 50%. I think that is a much more obtainable goal. I know that’s the plan in this household.
“ When The Motives Are Love Truths And Good Common Sense And Not For Profits.
Intro very interesting but huge logical flaw as it infers that the salt water of the oceans is not a massive source of fresh water. It is called evaporation and rain! It is not the same fraction of a percent that recycles itself. The ocean is a massive fresh water generator. I realize he eventually explains this but it makes the deceptive nature of the intro worse not better, in other words he knows better.
100 Gallons of water to make one loaf of bread. Again ignores the water cycle, as though it is like oil and burnt and gone. 100% of the water the wheat uses is returned to the water cycle, 100%.
This is pretty much a bunch of vegetarians in the comment section.
Build more dams
I love the indirect jab at the flerfers, but they will insist that N.A.S.A. compelled him.
Only vegans can go to space,
They gonna bake bread in space? Why don't they plant strawberries and tomatoes?
We will using replicatorsll
“ Our Almighty Lord Savior Beloved Blessed Christ Said my People Fail me For the lack of knowledge.
Spreading fake knowledge dont help..
Free fresh water is equivalent to a mustard seed ???? Come on, sounds like this guy made some humongous calculation errors - in the 100 orders of magnitude !
Sounds like you need to do a couple simple google searches
@@connor9434 yeah, it sure sounds like YOU need a course in critical thinking !
Well, it’s easy, wiseguy ! If you’re so clever, and already have verified his obscure claim - that the volume of all the earths freshwater only amounts to a mustard seed relative to a table globe of earth, then simply post your references for it here !
Anyway, his analogy is complete absurd as it’s only the surface area of the earth that is relevant/involved with life on earth , which ~ is less than 1/1000 of the earths radius (6366km)- much less if averaging the depth of the oceans and heights of the land (disregarding the various layers of earths inner cores) !
I guess you’re also the millions of hoodwinked believers in AGW - Anthropogenic global warming-- the absurd and absolute unproved, ridiculousness non-scientific based belief that human activity is the major source of Global warming / climate change and that CO2, the plant food, that green house gardeners use to speed up the growth of plants, while reducing their water consumption is a significant driver of average global temperatures ! Well, I hope I’m wrong and you’re wiser than that , but please send me the reference
Another go eat bugs talk. More LACK thinking!
earth is flat
False. It’s velociraptor shaped.
We found the weirdo! 😂
LOL, acting like we can't desalinate water and that better methods of doing so aren't being developed all the time.
Which better process is less man-made energy-intensive?
propaganda anyone
u want Improve? go vegan, don't torture around
lucy diamonds it's like telling people to stop driving cars, you cannot just convince humans to change their ways especially when the norm of meats has been in Human psyche since the dawn of civilization.
My friends, the culture of violence will annihilate us, at the end, it s evolve or perish, seems impossible in the beginning but vegans are saving the world n we grow, cose more ppl open their minds n eyes, n no, it s not like stopping the cars, it s much easer, once u discover the love in yr heart u won't heart them any more, life become easier 4us 2
There is a split in consciousness levels now, and the rift is only widening as we move forward to a new age/yuga.
Let others do as their consciousness level and awareness drives them. They will live the consequences later
Just continue to live by your inner guide consciousness and move forward. You cannot change another - as the process is an inside job. The conditioned and learned social behavior pattern can be too difficult for some to change in this yuga cycle
Too many flawed assumptions to be taken seriously
Earth is flat this guy is full of propaganda.
Yes, the Earth is flat without any doubt.
Everything was ok until the part "eat less meat". So wrong this.
Lots of BS factoids...the earth is amazing and he does not understand it. It is not a zero sum game. I think he is a politician, not a scientist.
