As Tavish Campbell dropped his remote camera into the water close to a salmon farm in the Broughton Archipelago, his heart sank.
Earlier in the day, during a dive, he was awestruck by the sight of an ancient, rare and previously undiscovered glass sponge reef in the water off Port Hardy, but now he was staring into the barren ruin of a second glass sponge reef.
“The one was totally alive and vibrant and healthy and the other one was a wasteland, covered in brown sediment,” Campbell told DeSmog Canada.
