The next thing is that if you want to predict the effect of one species on another, if you focus only on that link, and then you black box the rest, it's actually less predictable than if you step back, consider the entire system -- all the species, all the links -- and from that place, hone in on the sphere of influence that matters most.
其次，如果你想要预测 物种间彼此的影响， 如果你只专注那个链接， 你就会忽略掉其它的信息， 但是你会更难做出推测 如果你退回上一步，纳入整个系统，包括所有物种、关联 从这里着手 把焦点集中在相关的影响范围效果会更好。
