"We start working with the new ocean," Elias corrected. "The old one is gone. This one runs hot and sour. We adapt, or we drown."
The most devastating climate contribution of aquaculture is indirect. Between 1980 and 2000, approximately 35% of global mangrove cover was lost, with shrimp farming responsible for more than half of that destruction in Southeast Asia. Mangroves are among Earth’s most efficient carbon sinks, storing up to 1,000 tons of carbon per hectare—four times that of tropical rainforests. When converted to shrimp ponds, this stored carbon is oxidized and released. Each hectare of converted mangrove represents a climate debt equivalent to driving a car for 100,000 kilometers.
For generations, men like Elias had chased fish across the open ocean. But the ocean had changed. The wild catches were shrinking, the fish migrating into deeper, illegal waters, or simply vanishing. The future of protein, the economists said, lay in the cage. This was the "Blue Revolution"—farming the sea to feed a warming world.
