The Natural World Vanishes:
How Species Cease To Matter
Once, on both sides of the Atlantic, fish such as salmon, eels, and, shad were abundant and played an important role in society, feeding millions and providing a livelihood for tens of thousands. But as these fish have steadily dwindled, humans have lost sight of their significance, with each generation accepting a diminished environment as the new norm.
BY JOHN WALDMAN
... Every generation takes the natural environment it encounters during childhood as the norm against which it measures environmental decline later in life. With each ensuing generation, environmental degradation generally increases, but each generation takes that degraded condition as the new normal. Scientists call this phenomenon “shifting baselines” or “inter-generational amnesia,” and it is part of a larger and more nebulous reality — the insidious ebbing of the ecological and social relevancy of declining and disappearing species.
