These artificial great plains are making wild grasslands amongst the most endangered habitats on Earth.

这些人造大平原使野生草原成为地球上最濒危的栖息地之一。

So we've learnt how to find food in the wild grasslands, either on our own, or with a bit of help from others.

我们已经学会如何在野生草原寻找食物，依靠自己或者从其他生物那儿获得点帮助。

Yet it was on the wild grasslands, which support vast grazing herds, that we achieved perhaps our greatest triumph: to subjugate these animals to our needs.

然而正是在这养育了大量畜牧的野生草原上，我们获得了或许是最大的成功：使这些动物服从于我们的需要。
