After the Nazis Came War Against Fish
WWII technology has caused trillions of casualties at sea

It is Victory in Europe Day, the end to a global catastrophe that cost the planet at least 60 million lives. But if we were fish, we would have marked the day differently — as the beginning of a campaign of violence against our taxonomic classes, one that has resulted in trillions of casualties.
Oddly, the war itself was a great reprieve for many marine species. Just as Axis and Allied submarines and mines made the transportation of war matériel a highly perilous endeavor, they similarly interfered with fishing. The ability to catch staple seafoods, like cod, declined markedly. Freed from human pursuit, overexploited species multiplied in abundance.
But World War II also brought a leap in human ingenuity, power and technical ability that led to an unprecedented assault on our oceans. Not only did ships themselves become larger, faster and more numerous, but the war-derived technologies they carried exponentially increased their fishing power.
Take sonar. Before the 1930s, electronic echolocation was a barely functioning concept. It allowed operators to trace the vague contours of the seafloor topography…
