几千年来,他们开始减少对野外狩猎和采集的依赖,而更多地依靠自己饲养的动物和播种的庄稼。
Over thousands of years, they began to depend less on what could be hunted or gathered from the wild, and more on animals they had raised and crops they had sown.
相反,他们慷慨激昂的呼吁生产更多“人道”饲养的动物肉。
Instead, they make impassioned calls for more "humanely" raised meat.
这就是为什么人们很容易对着农场饲养的动物(或小孩)发怒。
That's why it's easy for people to blow up at farm animals (or at small children).
So it was a major change in human evolution where people started raising animals in large groups or started growing plants in large amounts.
这在人来演化史上是个巨大的变革,人类开始大规模饲养动物,或是大量种植农作物
