Honest question: How does that scale up? At first guess, I'd imagine there's insufficient area in (non-polluted) river mouths to create a large enough sustainable supply for world-wide demand.
Why does it need to scale up? I think scaling up is what caused problems with our planet, we need to start thinking locally.
For Connecticut, this is a local issue (too much Nitrogen in the sound) and this is a local solution that not only _reverses_ a problem, but produces real food and economy.
This economy doesn't have to be at scale, other places on this earth have different problems and require different solutions.
We need to work with nature, not against it. Let nature do the work. A healthy natural system is the true meaning of wealth in this world, it works without ANY human or oil expense. A fly-wheel system that generates money without effort.

Extensive monitoring and modeling of Long Island Sound have identified the excessive discharge of nitrogen from human activities as the primary pollutant causing hypoxia. "
