Charles Mann is worried that so few of us have any notion of the giant, interconnected systems that keep us alive and thriving. His new series, How the System Works at the The New Atlantis, is a primer to civilization. As you might expect from Mann, it’s beautifully written with arresting facts and images:

The great European cathedrals were built over generations by thousands of people and sustained entire communities. Similarly, the electric grid, the public-water supply, the food-distribution network, and the public-health system took the collective labor of thousands of people over many decades. They are the cathedrals of our secular era. They are high among the great accomplishments of our civilization. But they don’t inspire bestselling novels or blockbuster films. No poets celebrate the sewage treatment plants that prevent them from dying of dysentery. Like almost everyone else, they rarely note the existence of the systems around them, let alone understand how they work.

…Water, food, energy, public health — these embody a gloriously egalitarian and democratic vision of our society. Americans may fight over red and blue, but everyone benefits in the same way from the electric grid. Water troubles and food contamination are afflictions for rich and poor alike. These systems are powerful reminders of our common purpose as a society — a source of inspiration when one seems badly needed.

Every American stands at the end of a continuing, decades-long effort to build and maintain the systems that support our lives. Schools should be, but are not, teaching students why it is imperative to join this effort. Imagine a course devoted to how our country functions at its most basic level. I am a journalist who has been lucky enough to have learned something about the extraordinary mechanisms we have built since Jefferson’s day. In this series of four articles, I want to share some of the highlights of that imaginary course, which I have taken to calling “How the System Works.”

We begin with our species’ greatest need and biggest system — food.

and here’s one telling fact from the first essay:

Today more than 1 percent of the world’s industrial energy is devoted to making ammonia fertilizer. “That 1 percent,” the futurist Ramez Naam says, “roughly doubles the amount of food the world can grow.”

Addendum: Tom Meadowcroft from the comments: I teach chemical engineers, who are expert at understanding, designing and managing processes, and will be running many of these civilizational processes after they graduate. Even amongst that group of very bright thinkers, there is remarkably little knowledge as to how we achieve clean water, reliable electricity, fuel for transport and industry, dispose of sewage, and grow and distribute food. These same young adults can all tell you about colonial mindsets, how the world is going to burn, and how various groups are victimized. Our K-12 education system has very warped priorities and remarkably ignorant people at the front of the classroom.
