Until about eleven thousand years ago, when our ancestors settled down in the first agricultural communities.

直到大约一万一千年前，我们的祖先在第一个农业社区定居下来。

Agricultural communities like this were slowly springing up around the world.

像这样的农业社区正在世界各地慢慢兴起。

But over time, they were absorbed into the agricultural communities that surrounded them.

但随着时间的推移，他们被吸收到周围的农业社区中。

And if we do that, it's gonna lead to large and small agricultural communities being bought out and dried out, and those communities will literally die.

如果我们这样做，就会导致大大小小的农业社区被买断和干涸，而这些社区将彻底消亡。
