It could be the dams, fertilizers, pesticides, and related reduced food availability. It might have to do with the amount of water in the region, climate change, and poor regulation. Most likely, it’s some combination of these factors compounded by widespread apathy about a population of chinook salmon off the coasts of Northern California–until it was too late. The Press Democrat quoted fisherman Al Vail:
“I never caught a fish,” he said. “I’ve never seen a year like this, and I’ve been fishing for 45 years.”
Sad, but is anyone surprised? Those with an eye to the fishery knew this news would come. The farmers, the environmentalists, the scientists, the fishermen, and much of the public observed and waited. Tragedy of the commons? Perhaps. Tragedy for the fishery and those involved in industry? Obviously. Next up… Blue Fin Tuna?
