If we are going to impose a cultural change on the world population, adding sea weed and shellfish would be better from an ecological perspective with lower footprint. Rather than using 75% of pesticides, herbicides and fertilizers, aqua farming is closer to 0%. It also dont contribute to killing the oceans like argiculture does. If we want to scale up food production on earth leaving as much land as possible for nature and humans, the ocean offer plenty of space for food production.
