What if your kitchen fridge is just the tip of an iceberg that’s reshaping the world? Food storyteller Nicola Twilley reveals how the massive “artificial Arctic” we built to keep our food fresh is simultaneously melting the real one. She shows why we’re at a critical moment to rethink our relationship with the cold chain and refrigeration — and explores the emerging technologies that could keep food fresh without putting the planet on thin ice. (Recorded at TED Countdown Summit 2025 on June 17, 2025)

    What a terrible shame I was so excited to listen to this. She understands the problem, but of course she’s applying a exploitative capitalist techno feudal model to the solutions. The solutions are that we need to create local resilient food systems and we need to create diets that promote community well-being, individual well-being in planetary well-being by restoring the Earth through regenerative cropped farming, not by flying chickens around and drones. What a shame I was so excited to listen to this talk and once again, it’s a monetary techno solution that’s being promoted for something that human beings have done without any of this garbage for hundreds of thousands of years it’s really too bad.

      You put it better than I could have. Exactly my problem with this TED talk. Once again it’s blaming normal people for the actions of the wealthy and the powerful.

      @homewall744 please excuse the dictation errors. I’m actually driving around collecting fish waste to feed two pigs because somebody actually has to do some real work around here.

    • @andrewj1754

      I agree. However she is trying to suggest capitalist solutions, because that has scale to change faster than individuals hearts and minds.

      I agree with you on what the real solution is. But I also think there are so many people out there who don’t care, or who have worse problems that they aren’t going to apply it, so need capitalism to bridge some of the gap.

      Ultimately I don’t think additional plastics or more chemicals on our food is a better choice in the slightest. But we need a wholistic view of all of it, and a transition plan to the sustainable state.

    • @SeegerInstitute

      December 27, 2025 at 7:31 pm

      @andrewj1754 OK so I agree with everything you just said so when you suggest that a capitalist solution is necessary for scale you’re saying that we need to run faster in the direction that we already know is killing the planet, destroying communities and destroying human health? I am proposing a holistic solution which involves regenerative agriculture, and reimagining what we now view as in the public sphere as something that is considered a commonwealth, something that we all share responsibility for and all care for. I understand it’s a bit utopian, but I also believe that our financial system is it a point of catastrophic collapse, and then an argument can be made that for an inconsequential amount of money invested privately on the part of high net worth individuals we can introduce holistic solutions as models on which the dominant paradigm can reflect, and perhaps begin to change in a way that we can overcome a bad model within which we are deeply unwinded

    She’s got the demeanor of a brainwashed true believer. Even so, I was sort of listening until she started spewing lefty nonsense about EV’s and bikes. It’s the economy stupid. If you want a paradigm shift, then make it make sense monetarily.

    • @fbaallied

      December 27, 2025 at 2:32 pm

      What’s wrong with EVs?

    • @johnholsti2724

      December 27, 2025 at 5:40 pm

      @fbaallied Nothing intrinsically, they just shift the locus of fossil fuel. EV’s are coal fired cars. Nothing wrong with that, but it’s not saving the environment.

    • @fbaallied

      December 28, 2025 at 2:30 am

      ​​@johnholsti2724Don’t disagree, but surely its alot better than those gas guzzlers?

    • @johnholsti2724

      December 28, 2025 at 6:40 am

      @fbaallied It takes a certain amount of energy to move a vehicle. That can’t be changed. In my opinion, it doesn’t matter if you are generating that energy at a coal fired power plant, or onboard petroleum combustion. The energy requirements are the same. Storing energy is the weak link. Battery technology hasn’t arrived. They are too inefficient to make the switch. When that does happen, and I think it will, the market place will make the switch voluntarily.

    • @Xienixnlpsc

      December 28, 2025 at 9:04 am

      ​@johnholsti2724 the energy and emissions required to make an EV are a lot higher in comparison to an ICE car.

      However, this does not necessarily mean that EV’s aren’t there yet. It will take a certain milage to reach a break even point when it comes to total emissions. After those miles your EV will be cleaner.

      This breakeven point depends on how the electricity you put into the car is produced. It will take longer to reach the breakeven point if the electricity has been generated with coal. But you’ll reach it faster if it comes from a solar farm. There is a break even point for every single EV though.

      So it depends how often do drive. Do you only drive once or twice a week? Then it might genuinely be better to drive a gas car. Do you drive a lot?… Then the EV will probably be the best long term option.

      The battery efficiency is not necessarily the problem. You can leave the EV plugged in over night and just drive to/from work without any issues. Yes there are a handful of edge cases like a road trip… But the majority of people only use their car to drive short distances. (this is from a European perspective)
      Also under developed/poorly maintained charging infrastructure can be a pain to deal with.

      EV’s are the future, there’s no question about it. Add some good public transport in the mix and it’s going to be great!

      Teaching the public about electric cars seems to be the main problem. There are so many stubborn people out there, the gas car is all they know and they will do the weirdest mental gymnastics in order to come up with an argument against EV’s. Which causes a lot of miscommunication about EV’s in general. Both cars have pros and cons, but imo the EV is the superior one (for the majority of people)

      This was my ted talk 🙂

    Does “less than half the emissions” include the extractions and manufacture of the plastics? How about degradation of plastics into air, soil and water?

    • @andrewj1754

      December 27, 2025 at 7:15 pm

      Yeah, I was with her until I heard a solution was more plastics.

    • @charlesk2850

      December 29, 2025 at 10:50 am

      Plastic is far more “green” than natural alternatives

    • @justuschickens-e8f

      December 29, 2025 at 1:34 pm

      @charlesk2850 Basically what you’re saying is that we are doomed then. According to a 2016 World Economic Forum report, plastics in the ocean will outweigh fish in the ocean by the year 2050, at current rates of accumulation.

    They want you to eat bugs and be happy

    • @jaegrant6441

      December 27, 2025 at 11:53 pm

      Nothing wrong with bugs. They are a long standing staple of many cuisines, including some European.
      They are also easy protein to produce at home/small scale local. Reducing the need for agriculture corporations and exploiting workers.
      Changing your mind set towards eating bugs is one of the best ways you can shove it to the deep state.
      Yet, somehow the deep state have managed to convince people that the protein source the corporations can’t control is a deep state plot 😂😂

      Someone only woke up this decade lol🎉

    So is the “new way to refrigerate” done by the poor, or also by the rich? Is the nano crap created by the poor, or also by the rich? Is all the medicine and vaccines produced by the poor, or also by the rich? Is she on YouTube, using electricity, the web/Internet, doing a TedTalk in Africa because of the poor, or also by the rich?

    How about focusing on information gathering sites like the Meta sites in Idaho and Utah that consume mass amounts of energy and cost a ton to operate?

      December 28, 2025 at 7:24 am

      The cashew apple is the same for Western countries. They get the cashews, but they have never tasted a cashew apple because it rots too fast even with refrigeration.

  17. @sagarlamsal8248

    December 27, 2025 at 10:58 pm

    Yes. If you chill it, it breath more slowly and lives longer. The general concept to freeze our veggies is for the freshness as they have better anti-aging tech. But, refrigeration in the name of freezing accounts for between 2.5 -3% of all global emissions.
    Really the insightful talk regarding the alternative we need to think about our refrigeration system.

  18. @jaegrant6441

    I have lived for well over 10 years without a fridge at all. Shop less, eat things that keep more easily and remember that things kept under well soaked cloth remain cooler longer. And for icecream? I support my local icecream parlour by being an occasional customer. It doesn’t have to be everything everywhere all at once….

    What kept me watching past the first ad was the speaker’s delightfully perfect enunciation. Such a treat in today’s world of mumble mumble. Also, some good food for thought. I always marveled at the British small refrigerators but now as an elder who eats very little I see an awful lot of wasted real estate in my energy hogging apartment sized refrigerator.

    Subsistence farming is a way of life so miserable, bleak, and fraught with danger we spent millennia trying to escape it.
