Could the future of farming rely on pooping fish? Considered to be a sustainable alternative to traditional farming, aquaponics is changing the way we grow food. ➡ Subscribe: http://bit.ly/NatGeoSubscribe #NationalGeographic #Aquaponics #Decoder About National Geographic: National Geographic is the world's premium destination for science, exploration, and adventure.

Get More National Geographic: Official Site: http://bit.ly/NatGeoOfficialSite Facebook: http://bit.ly/FBNatGeo Twitter: http://bit.ly/NatGeoTwitter Instagram: http://bit.ly/NatGeoInsta As the world population increases and urban areas expand, the amount of land suitable to grow crops is shrinking, but aquaponics offers an innovative solution that could feed millions of people without a need for soil. It works by raising fish and plants together in a contained water system. The fish produce waste, which is filtered to remove solids and transformed into nutrient-rich water through a two-step bacterial process. The enriched water is then pumped into a separate tank where seedlings float on soil-free growing beds, illuminated by special LED lamps that provide optimal light for growth. Through this method, crops grow 20 percent faster than plants grown using traditional farming techniques. For that reason, aquaponics is emerging as a sustainable option for cities, islands, and developing regions where land and water resources may be limited. Learn how this ever evolving technique is growing food for the future in this latest video from Decoder: https://www.youtube.com/playlist?list=PLivjPDlt6ApQYPw1BUw0ziY-ztWAKOdSG For more, read "From Tank to Table" in the August 2019 issue of National Geographic magazine.

Aquaponics is being eyed as a sustainable farming option well suited to cities, islands, and developing regions where water and land are in short supply. https://on.natgeo.com/2T24xD9

Fish are not ours to eat.

Yes they are. Fish are food for many animals including humans. It is life.
Saryn Drast (6 months ago)
Interestingly enough, the majority of the worlds oxygen AND food come from the ocean. This is yet another reason why humanity absolutely has to clean up the ocean. Furthermore, many people believe that only land produced vegetation is edible. This could not be more false. A clean ocean can provide more organic nutrition than any land based farm ever could.

Saryn Drast (6 months ago)
That's why they use Tilapia, largely in part, they are plant eaters. Which contributes to the overall cycle of sustainability. The leftovers from the crops produced are used to feed the fish reducing cost and extending life cycle.

I'm growing an avocado tree in a water tank, so far it's working great but as it grows larger it needs more and more soluble fertilizers which aren't cheap, so this video will inspire me to get some fish to put in the water tank and see if that will help both the tree and the fish live together in a self sufficient eco system. Thanks for the video.

I think this quite misleading as only focusing one part of the "energy cycle" as they didn't measured the energy / process that needed to feed the fish

Raising insects could help with that problem. Use food waste to feed larvae, turn the larvae into pellets to feed the fish

Now vegans would say that they won't eat salads because this harms fish😂
Athanasia P (6 months ago)
Dana sure everyone is entitled to their opinion. On the other hand no opinion is true just because it's someone's opinion. All opinions are open to criticism. If you have an opinion you should be able to support it with facts.
Dana (6 months ago)
@Athanasia P as I said, it's my opinion after a lot of studying , I respect yours as well.
Athanasia P (6 months ago)
Dana we can stop all practices and projects that are harmful to animals and invest as a society to alternative practices that are not harmful to animals or people or the planet in general. We just choose not to.
Dana (6 months ago)
@Athanasia P Actually, I am vegan and against what is being done for animals but I'm saying that we can't stand against everything, or this is how it seems so, if we cut everything it won't be a life, someone is going to be harmed. After all, it's just an opinion of mine.
Athanasia P (6 months ago)
Dana you don't need to be a vegan to say that. It's a fact. It's a rubbish method.

Tanta boca para alimentar e muitas ainda morrem à fome ...Este é um sistema bastante funcional e criativo num circulo ...onde tudo se transforma e que pode colmatar ou ser uma vertente para alimentar!! Os Viveiros e a aquacultura e a água .. e de facto um método cheio de variáveis!! a questão que muitas vezes as pessoas colocam é o sabor do peixe?? A qualidade!! O peixe que escolhia seria o bacalhau..mas será uma realidade futura??
R E A (6 months ago)
Sounds interesting but the question is whether food grown this way will still have any nutrients. Already today food has way less nutrients than in the past because of the way we grow it...
Oliver (6 months ago)
If there were no nutrients the fish and the plants wouldn't survive so yes there are nutrients
lara croft (6 months ago)
Yeah I was thinking about the same
geeksquad smarty (6 months ago)
I thought this was the way all water plants were grown in nature on their own. Isn't this the way seaweed is grown. Isn't this the way lily pads have grown in nature.
underdog5004 (6 months ago)
I run my own backyard aquaponic system, and I grow a lot more than lettuce. Zucchini is the most fruitful now, but my lemon cucumbers, beans and tomatoes are also exploding with growth and fruit. I'm growing kiwis and strawberries. Just harvested a double handful of strawberries. Sweet and tasty. If the nutrients are available in the water, and the ph is low enough, the plants will take up the nutrients and be more nutritious for the people who eat them. Besides fish food, I add sifted wood ash and Epsom salt as periodic supplements. I need to add iron every 6 months or so, and calcium sometimes too. It's not the most efficient or cost effective way to grow food, but it's fun, stimulating, and gratifying to set up my own system, and enjoy the produce that is produced.

Thijs van Esch (6 months ago)
So it is basically a greenhouse coupled with a fishery, making only the delivery of nitrate more easy? Interesting concept, but most the speed of the growth cycle has nothing to do with the fish. That would occur in a normal greenhouse as well. It would be also possible to couple a waste water treatment plant. It does exactly the same thing but with human waste, no fishery needed. Only thing which needs to be overcome is that people don't like to know that, and if they do, might be less likely to consume plants grown in such a manner.
Bunny_2007 (6 months ago)
@Thijs van Esch that's my point. I take medication daily for anxiety. Unlike other animals we humans have to take meds for many reasons, for me it's for my mental health. Something I have to take the rest of my life. This is why human waste is a bad idea.
Thijs van Esch (6 months ago)
@Bunny_2007 i don"t know where you come from, but in the netherlands wastewater trearment plants use mostly bacteria for denitrification and such as show in the video. The problem is here more the medicin rests which are very hard to filter out.
Bunny_2007 (6 months ago)
Cant use human waste because of our diet and disease we carry, because of this human waste has to be treated with harsh chemicals which is bad for growing plants we have to eat.

Sustainable agriculture is the way to move forward. Gotta use the most efficient way to feed all of us hungry people. 😀
Yono Sepe (6 months ago)
H. Yahaya I have already made my point you simply will never acknowledge it and keep pushing the aquaponics and hydroponics which I was not talking about; sustainable agriculture is not limited to those two means of cultivation, you are ignoring the socio political factors that go on in less developed countries; quinoa yields very little harvests in relation to time and surface area, nevertheless it is still being promoted and consumption is being abused; I assure you that if you take your time to study and research you will realize that my point is very simple yet you do not want to grasp it because it goes against what you believe not what you know as clearly your knowledge is limited to sources that follow your narrative and a critical perspective on them and their sensationalism is something you cannot withstand.
H. Y. (6 months ago)
@Yono Sepe absolutely.no.point. Come back when you have real answers apart from "fallacy". Til then: You.have.no.point.
Yono Sepe (6 months ago)
H. Yahaya even if I take the time to explain meticulously you will refute whatever I say; sustainable agro is a fallacy it is not the answer to hunger that is my point.
H. Y. (6 months ago)
@Yono Sepe sorry. I'm having trouble to understand your train of thought. You do realize you said agriculture is bad in the beginning right? And as pointed by the @Azlyana sustainable agri is the way forward. So.. what's your problem with sustainable farming? Your opinion is based on a negative sentiment towards traditional farming (which is NOT what the video is about). And now you went about people not adopting sustainable farming (while ignoring the fact to admit you didn't bother to understand this video which in essence is about sustainable farming). Truth is, you have no point.
Yono Sepe (6 months ago)
H. Yahaya yes a growing effort but it won't be adopted in a wide scale; these efforts are isolated cases in relation to the number of agro dependent poor people in these countries; it is a fallacy
