We humans are now so aggressively fishing, hunting, logging, and growing crops in all parts of the world that we are literally chasing other species off the planet. Our intense desire to take all that we can from nature leaves precious little for other forms of life.
作为一个物种，人类存在很大的自我控制问题。我们人类现在全世界所有的地方如此大肆捕鱼、打猎、采伐和种植作物，乃至我们实际上在把其他物种从地球上驱赶出去。我们极度想要从大自然中索取所有我们可以索取的东西，留给其他生物种类的东西少之又少。
