Nautilus - The Box That Built the Modern World 5-15min

More than any other single innovation, the shipping container—there are millions out there, all just like the ones stacked on the Hong Kong Express but for a coat of paint and a serial number—epitomizes the enormity, sophistication, and importance of our modern transportation system. Invisible to most people, they’re fundamental to how practically everything in our consumer-driven lives works. ... Think of the shipping container as the Internet of things. Just as your email is disassembled into discrete bundles of data the minute you hit send, then re-assembled in your recipient’s inbox later, the uniform, ubiquitous boxes are designed to be interchangeable, their contents irrelevant. ... The exact placement of each box is a critical part of the equation: Ships make many stops, and a box scheduled to be unloaded late in the journey can’t be placed above one slated for offloading early. Imagine a block of 14,000 interlocked Lego bricks—now imagine trying to pull one out from the middle. ... The container’s efficiency has proven to be an irresistible economic force. Last year the world’s container ports moved 560 million 20-foot containers—nearly 1.5 billion tons of cargo altogether. Though commodities like petroleum, steel ore, and coal still move in specially designed bulk cargo ships, more than 90 percent of the rest—everything from clothes to cars to computers—now travels inside shipping containers. “Reefer” containers, insulated and equipped with cooling units, carry refrigerated cargo and are plugged into power sources on ships or at dockside. Because the containers are all identical, any ship can move them. ... The Port of Los Angeles, America’s busiest container port, handled 476,000 TEUs in 1981. Thirty years later, 7.9 million 20-foot containers—almost all of them containing goods on their way from factories in Asia—moved through the port, a 16-fold increase. Hamburg’s four container terminals loaded and unloaded 8.9 million TEUs in 2012. On the long list of global container ports, Hamburg and Los Angeles are middleweights: Shanghai, the world’s largest container port, moves 31 million TEUs each year.

Zarnkow is one of a group of researchers who over the past few decades have challenged that story. He and others have shown that alcohol is one of the most universally produced and enjoyed substances in history—and in prehistory too, because people were imbibing alcohol long before they invented writing. ... Chemical analysis recently showed that the Chinese were making a kind of wine from rice, honey, and fruit 9,000 years ago. In the Caucasus Mountains of modern-day Georgia and the Zagros Mountains of Iran, grapes were one of the earliest fruits to be domesticated, and wine was made as early as 7,400 years ago. ... All over the world, in fact, evidence for alcohol production from all kinds of crops is showing up, dating to near the dawn of civilization. ... From our modern point of view, ethanol has one very compelling property: It makes us feel good. Ethanol helps release serotonin, dopamine, and endorphins in the brain, chemicals that make us happy and less anxious. ... To our fruit-eating primate ancestors swinging through the trees, however, the ethanol in rotting fruit would have had three other appealing characteristics. First, it has a strong, distinctive smell that makes the fruit easy to locate. Second, it’s easier to digest, allowing animals to get more of a commodity that was precious back then: calories. Third, its antiseptic qualities repel microbes that might sicken a primate.
