In 1928, Jiaozhou Bay covered 560 square kilometers of the Yellow Sea, a broad natural harbor on the southern coast of the Shandong Peninsula. By 2003, sustained land reclamation had shrunk it to 362 square kilometers, roughly two-thirds of its former self. The bay that Kaiser Wilhelm II coveted, that Japan seized, that ignited student protests across China, and that now sustains one of the world's busiest ports has been physically diminishing even as its significance has grown. Out of 170 marine species found in its northwestern basin during the 1970s, only 17 remained by 1989. False killer whales, once regular visitors, now appear only occasionally. Jiaozhou Bay is a place where grand history meets ecological reckoning.
