Rising carbon levels in the atmosphere can make plants grow faster, but there's another hidden consequence: they rob plants of the nutrients and vitamins we need to survive. In a talk about global food security, epidemiologist Kristie Ebi explores the potentially massive health consequences of this growing nutrition crisis — and explores the steps we can take to ensure all people have access to safe, healthy food.
The TED Talks channel features the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes (or less).

so nothing to do with food plants being gentically altered?
@Scott Henrie yeah the faux environmentalists really did golden rice dirty,it could have saved millions of starving children
@someone The treatment of GM technologies in general is extremely unfair, but to the best of my knowledge the assimilation rate for vitamin A precursors engineered to be produced in the golden rice was lower than anticipated in nutritional trials anyway.
A similar story is the one where wheat was engineered to include aphid-repelling allomones, it worked at a small scale in the laboratory but didn’t at field-scale because the aphids ignore it when it is abundant.
On the bright side, there was that research group that made a GM Arabidopsis that turns purple when it grows on top of a landmine, so there’s some potential use for clearing up war zones with that.
@someone IDK about starving, but it’d prevent the health problems from vitamin A deficiency. I think night blindness is one of the problems.
@Scott Henrie Genetic modification/ genetically modified! :^D
Hate to break it to this presenter , our food has become less nutritious due to over cultivation and gmo crops .
Ted talks unfortunately has lost some objectivity .
What a shame .
Do you have any information to support your argument? I would love to see that. Knowing that GMOs have saved thousands or not even millions of acres of land, while making plants and animals more nutritious for human consumption. I don’t know how people hate GMOs so much. They would be a good ally in fighting global warming.
Silvia Chamlee prove it. You must work for government. That is all.
@Rick James I am government man, come from the government. The government has sent me.
Dan Cattell Art awesome.
Silvia is right. Do your homework you idiots.
I think a study should be done to see if food has different amounts of nutrients with seeds from the same plant and in a greenhouse where they can control the levels of CO2.
@Sovereign Rex Did you watch the video? It’s opposite, she did research with higher CO2 than today!
Yes, plants are growing faster but they are less nutritious. Rice example, proteins 10% less, iron 8% and zinc 5% less with higher CO2!
@Kloko Loko what about the variables, like available nutrients in the soil?
@Sovereign Rex that’s why I’d like a better study done where they can control the variables. I think they should mix the soil used in a huge machine, so it’s more averaged. Maybe hydroponics? Also, CO2 is how trees and all plants are able to get water and nutrients from the soil. https://youtu.be/BickMFHAZR0
Higher temperatures offset the adverse effects of CO2 on crop nutrition:

Another problem of whole this point is that they are talking about trace elements in plants which are hardly accessible for us. We must eat animals meat, where these elements are much more accessible for us. If we only had 4 stomachs! 🙂
Since the caveman till now….quite sure there’d been quite a few climate change.
But never this quick.
Dan Cattell Art whatever dude? Have you been “chill’in” on the planet taking temp readings for the last 4 billion years?
ANDY VAN KERKHOVE always love the clown face! That’s all you need to respond back to these climate change maniacs
You realize that unsustainable farming practices have already done this by depleting the topsoil, right?
@Dan Cattell Art It dosent, why do you think the color of the product changes over time as its exposed to oxygen. In the grocery store you can even noticeably differentiate the two by the marks on the organic product. If they had wax or pesticides they wouldn’t show any signs of spoil. You can even test it yourself in all honeslty. Buy an organic apple and a non organic apple then see which one spoils first.
@Dan Cattell Art Farmers care about shelf life and how much money they make from sales instead of the safety and health of their consumers
Giovanni Ferraro it’s been proven time and time again that organic produce are covered in feces are WAY less healthy and nutritious. Not only that, people will choose the commercially grown produce over organic 9/10. In fact there is an entire episode of Penn & Teller “Bullshit” where the entire Organic Produce racket is exposed. NOBODY chose the organic produce in a blind taste and visual test. Not one person picked the organic. Organic equals E.Coli to the educated. You fn dolt.
Nick Farley Not true. Factory farming practices are unsustainable but there ARE very sustainable ways to raise animals for meat.
I thought it was farming methods that reduced the nutritional value of our food.
Well yes, both do.
climate change BS , TeD should be ashamed
Educate yourself
Hearing a lot about this “climate change”, when’s it changing and where?
I got my popcorn ready
what
@NeoHelisa they’re one of the people that aren’t as easily brainwashed by repetition or confusion. This has links to the sources for the archived newspapers and websites. https://cei.org/blog/wrong-again-50-years-failed-eco-pocalyptic-predictions
She doesn’t look healthy. Maybe some garden fresh ORGANIC food would help. Oh wait, home gardens and self reliance is increasingly ILLEGAL! AGENDA 21 SMART CITIES and DEPOPULATION is the plan! Total dependence on the government. Madatory vaccines and soylent green chips if you are good and keep your social credit score up. Free thinking will not be tolerated in the track, trace, and surveillance future.
Watermelon…..Green on the outside and red on the inside. AGENDA 21. Georgia Guidestones- keep population to under 500 million.
Flat earth. Atoms don’t exist. It’s cold in pappy’s barn, so earth is cooling.

These guys are doing it right !!!!
Starts with Food Pyramid = immediate thumbs down. The Food Pyramid is the product of the USDA, whose purpose is to promote the consumption of American agriculture. Guess what America grows really well? Corn & wheat! So they are promoted as the basis for a “balanced” diet; to drive demand in the American cash crops. It never had anything whatsoever to do with healthy eating.
well the food pyramid is no longer promoted by the usda.
@Joannot We’ve moved on to the “plate,” which promotes a ‘balanced” diet…still not focusing on nutrition.
Climate change may just sneak into our homes at night and strangle us in our sleep.
That’s happening slowly over time in several countries in Asia. The only real problems from air pollution are places like Beijing, China and New Delhi, India with high levels of fine particulate matter (PM2.5) pollution. These fine particles pose a threat to human health because they are small enough to enter the body by penetrating the lungs.
Here’s a real-time map of the air quality index for the world measuring PM2.5. http://aqicn.org/map/world/
You can help this air quality index map be more accurate by buying this sensor. http://aqicn.org/gaia/

People seem to forget or they don’t know at all that newspapers get archived.
They are ridiculous.
no thats not climate change…thats MONSANTO who is fooking with our foods.
Haha where do you find these idiots? 🙂 Make up a problem then “find” the solution. The way people have been controlled by their rulers since beginning of time.
Lower nutrition has to do with GMO and farming methods where the soil is destroyed. Always what happens when humans try to “fix” nature.
It just grows more with more CO2. Noone can do antyhing amout climate change. It has been chaning since the birth of the earth. What we can do though is to remove industrial farming and give it back to the people locally. More natural meat and veggies. No GMO:s or “beyond” meat and all that crap that no humans or animals ever evolved on.
Something needs to be done about the millions of people that die each year from air pollution, mainly in China and India. _“Even though India and China have the most deaths from air pollution worldwide with 1.61 and 1.58 million respectively, the statistics paint a different picture when it comes to age-standardized deaths per 100,000 inhabitants.”_ https://www.statista.com/chart/13575/deaths-from-air-pollution-worldwide/
@Scott Henrie Ha. This is funnier.
these comments are hilarious – gmo`s are bad, organic is the solution to everything, climate change is a fraud…jfc, this is a science channel!
I second that notion, did any of these people listen to her last words.
Putin’s alt-right trolls have been working overtime targeting science channels lately. It’s a waste of time. Anyone capable of understanding what is being said won’t be put off by the comments of low-life knuckle-draggers.
Dude, turn off CNN
I have not watched this video but let me just say from the title (because I have to go to work): Food is already less nutritious than in years past!! Why? Because we don’t let the land rest and let the soil re-gather nutrients once it’s been sucked out by previous crops. This use to be common practice and for good reason.
There’s a lot of reasons our food is already massively low on Nutrients and not one of them have to do with climate change but rather common negligence in order to turn more profit. Now its convenient to bring up the lack of nutrients and use it as a spin for climate change.
