丹尼尔.保利：海洋的变动基准线

鱼越变越小的现象表明，在我们这个时代，海洋的状况已恶化。而丹尼尔.保利告诉我们，每次基准线下降，我们就把它说成是新的“常态”。究竟到何时，我们才停止往下降低标准。

People often believe the natural world they inherit is how it has always been, overlooking dramatic losses over time.

The phenomenon, called shifting baseline, means that as ecosystems degrade, expectations quietly move downward. Without preserving history or creating protected areas, society risks accepting only remnants of what once existed.
