It’s easy to take for granted that we can just walk into the kitchen and find food available (at least in developed countries). John Green explains how the world developed the system of agriculture that allows so many of us to access food easily.

Video Summary

Before the Agricultural Revolution, humans were mainly hunters and gatherers. But then, people started cultivating crops. They used what grew naturally in the area like rice in Asia and corn in South America. The reason agriculture works so well is that it gives control of the food supply to the person growing the food. This decreases the chance of starvation. It also creates a food surplus that provides more than enough food to feed everyone. This allows for specialization of labor because not everyone has to work gathering food, so they are free to do other things. No one is really sure what caused the Agricultural Revolution other than the desire for more food.
