Dear Humans,

We’ve been talking a lot about cereal crops–corn, rice, wheat. It’s because they are the foundations of our civilization. About 10,000 years ago people started planting these grasses on purpose, harvesting more than they needed, and selling the surplus. And they completely changed the world.

Because then cities sprung up. And when people gather together in cities they share ideas and tools and diseases. And they come up with religions and writing systems and laws and punishments. And it’s a lot of good stuff and there’s some bad stuff too. 

And none of what we have today would be possible without it. Because we’re still part of that story. And we get a say in how that story continues.

Sincerely,

Mr. Curt
