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

Bruh. Hydroponics have been around. Utilizing fish waste is not new. I was using it 20 years ago to grow crops.

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

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.
