In a few generations more, there will probably be no room at all allowed for animals on the earth: no need of them, no toleration of them. An immense agony will have then ceased, but with it there will also have passed away the last smile of the world's youth.

几代人之后，也许根本就不再有动物存在的空间：人们不再需要它们，也不再忍受它们。那时，一种剧烈的痛苦将已停止，而地球的青春的最后微笑也将随之逝去。
