🌾 Land of plenty: My chat (+transcript) with science journalist Charles C. Mann on the agricultural history you never learned

In the 1960s, a deep anxiety set in as one thing became seemingly clear: We were headed toward population catastrophe. Paul Ehrlich’s “The Population Bomb” and “The Limits to Growth,” written by the Club of Rome, were just two publications warning of impending starvation due to simply too many humans on the earth.

As the population ballooned year by year, it would simply be impossible to feed everyone. Demographers and environmentalists alike held their breath and braced for impact.

Except that we didn’t starve. On the contrary, we were better fed than ever.

In his article in The New Atlantis, Charles C. Mann explains that agricultural innovation — from improved fertilization and irrigation to genetic modification — has brought global hunger to a record low.

Today on Faster, Please! — The Podcast, I chat with Mann about the agricultural history they didn’t teach you in school.

Mann is a science journalist who has worked as a correspondent for The Atlantic, Science, and Wired magazines, and whose work has been featured in many other major publications. He is also the author of 1491: New Revelations of the Americas Before Columbus and1493: Uncovering the New World Columbus Created, as well as The Wizard and the Prophet: Two Remarkable Scientists and Their Dueling Visions to Shape Tomorrow’s World.

Intro to the Agricultural Revolution (2:04)

I don't think that people realize that the fact that most people on earth, almost the average person on earth, can feed themselves is a novel phenomenon. It's something that basically wasn't true since as far back as we know.

Pethokoukis: What got my attention was a couple of pieces that you've worked on for The New Atlantis magazine looking at the issue of how modern Americans take for granted the remarkable systems and infrastructure that provide us comfort, safety, and a sense of luxury that would've been utterly unimaginable even to the wealthiest people of a hundred years ago or 200 years ago.

Let me start off by asking you: Does it matter that we do take that for granted and that we also kind of don't understand how our world works?

Mann: I would say yes, very much. It matters because these systems undergird the prosperity that we have, the good fortune that we have to be alive now, but they're always one generation away from collapse. If they aren't maintained, upgraded and modernized, they'll fall apart. They just won't stand there. So we have to be aware of this. We have to keep our eye on the ball, otherwise we won't have these things.

The second thing is that, if we don't know how our society works, as citizens, we're simply not going to make very good choices about what to do with that society. I feel like both sides in our current political divide are kind of taking their eye off the ball. It's important to have good roads, it's important to have clean water, it's important to have a functioning public health system, it's important to have an agricultural system that works. It doesn't really matter who you are. And if we don't keep these things going, life will be unnecessarily bad for a lot of people, and that's just crazy to do.

Is this a more recent phenomenon? If I would've asked people 50 years ago, “Explain to me how our infrastructure functions, how we get water, how we get electricity,” would they have a better idea? Is it just because things are more complicated today that we have no idea how our food gets here or why when we turn the faucet, clean water comes out?

The answer is “yes” in a sort of trivial sense, in that many more people were involved in producing food, a much greater percentage of the population was involved in producing food 50 years ago. The same thing was true for the people who were building infrastructure 50 years ago.

But I also think it's generally true that people's parents saw the change and knew it. So that is very much the case and, in a sense, I think we're victims of our own success. These kinds of things have brought us so much prosperity that we can afford to do crazy things like become YouTube influencers, or podcasters, or freelance writers. You don't really have any connection with how the society goes because we're sort of surfing on this wave of luxury that our ancestors bequeathed to us.

I don't know how much time you spend on social media, Charles — I'm sure I spend too much — but I certainly sense that many people today, younger people especially, don't have a sense of how someone lived 50 years ago, 100 years ago, and there was just a lot more
