From marine reserves expanding beyond the Galapagos Islands to aquaculture and the unique preservation of a southeastern coast, EcoSense looks at ways people are managing our relationships where shore meets sea and beyond. In the Galapagos, a new marine reserve is the result of multi-national cooperation to save migrating animals from intense fishing pressures. In Cedar Key, Florida, one fishing community managed to pivot when environmental pressures caused the oyster population to crash. And how did only 100 miles of Georgia coast protect 33% of all the marsh on the entire east coast? On Tybee Island near Savannah, they're experimenting with marsh and dunes to deal with sea level rise.
