"Kelp and mussels. Integrated Multi-Trophic Aquaculture. The kelp absorbs the carbon and nitrogen, oxygenates the water, and buffers the acidity. We farm the seaweed to save the fish."

"We're changing the business model," Elias told Sarah as she joined him with a cup of coffee.

Elias wasn’t a scientist; he was a farmer. And farmers improvise.
