> The math of feeding 10 billion people only works if we farm the ocean

Even for marketing puffery, "only" seems reductive when most resource usage seems specific to a few animal products like cows and lamb: https://ourworldindata.org/land-use-diets

The broader point we were trying to make is that as population grows and arable land decreases, the protein mix will need to shift. Fish have a feed conversion ratio of around 1.0 to 1.5 compared to 6 to 10 for beef. They do not require land for grazing and aquaculture has significantly lower greenhouse gas emissions than most terrestrial livestock. That does not mean aquaculture is the only path forward but it is likely a bigger part of the equation than it is today, especially in regions where seafood is already a primary protein source. We are not arguing against plant based diets or other solutions. Just that aquaculture is underinvested relative to its potential and the infrastructure to scale it efficiently does not exist yet. That is the gap we are trying to fill.
