Episode Quotes:

On the birth of the idea of his book “Salt”

03:03: In my Cod book, I realized the importance of salt because you couldn't have a fishery if you didn't have salt. And my publisher was very interested in me doing something on salt and really pushed me to do it. And I kept saying, "But where's the story?" And then I realized that the story is that there was this ingredient, commodity, mineral, that was of tremendous value that nations would go through…. I mean, they founded colonies, went to war, and went to all these lengths to get this salt, and then salt lost its value. So what was it for? And I believe that is the trajectory of oil.

The role of salt and cheese in the international economy

22:35: You have to think about: Before the Industrial Revolution, if you wanted to have an international economy, what did you trade? Mostly food. And you couldn't trade food unless it was salted. So basically, if you didn't have salt, you didn't have an international economy. And as far as dairy farmers go, your possibility for trade was to make cheese.

Do we need to reprioritize our food?

43:19: The way I think commercial fishing should go, fish aren't going to be cheap. They can't be cheap. Cheap fish is the enemy, because if you're going to tell a fisherman to catch less fish, you better get more money for it, or he's going under. So does that mean that poor people can't eat fish anymore? This is a real question. It's a question about improving agriculture, improving beef and dairy, and everything that you do to improve it ends up making it more expensive.
