The earth's population is above 7.6 billion people. That's a lot of people who need to eat. Fishing is an especially large industry, but it's wreaking havoc for certain natural ecosystems and habitats. Some species are being fished in the tens of millions each year. Is there a better way? Bren Smith is a former fisherman who understood he was involved in a highly destructive industry. He then began working with a large salmon farm, but found it was essentially the same destruction. He began searching for a more sustainable way to fish and farm which led him to develop 3D ocean farms. What are 3D ocean farms? What sort of seafood is Bren able to farm? What are the benefits of 3D ocean farms versus traditional seafood farms?
