ヨーロッパバイソン
During World War I, occupying German troops killed 600 of the European bison in the Białowieża Forest for sport, meat, hides and horns. A German scientist informed army officers that the European bison were facing imminent extinction, but at the very end of the war, retreating German soldiers shot all but nine animals. The last wild European bison in Poland was killed in 1921. The last wild European bison in the world was killed by poachers in 1927 in the western Caucasus. By that year, fewer than 50 remained, all held by zoos.
