One day, although there will perhaps be little fear of the extermination of the wild animals around us, all will have become essentially pets, experimental animals, or livestock, or other wise will only be able to live in "reservations" marked out by humans, which is something that ecologists most wish to avoid.
有一天，可能我們周圍的野生動物，雖沒有滅絕之虞，卻都變成了寵物、實驗動物或家禽、家畜，否則也只能在人們劃定的「保護區」內活動，這恐怕是生態學者最不願見到的。
