Because this one species accounts for 99% of exports, and is bought more than any other item at the grocery store. Walmart’s bread and butter isn’t actually bread or butter, but bananas. And it’s one of the most important crops in developing countries, along with staples like rice, corn, and wheat. Which makes sense, Bananas are nutritious, conveniently packaged by nature, and, dirt cheap. In the United States, bananas cost an average of just 56 cents a pound. Roughly 19 cents each. Cheap enough that Amazon just gave them away in Seattle. And that’s from a company which… literally sells air. Oranges, in comparison, cost just over two dollars a pound. Strawberries, three thirty-four, and apples, a dollar sixty-two. The difference is, bananas are picky. They require extremely rich soil, protection from the wind, and lots of water. They can really only grow in this narrow region - about 30 degrees north or south of the equator. That eliminates Europe and most of the United States, give or take a volcano and alligator. So, if you live here, in the banana belt, a country like Brazil, India, or China, your bananas are grown locally. For the rest of us, they’re imported from Central and South America - usually Ecuador, Guatemala, or Costa Rica. Apples, on the other hand, take what they can get. They survive in many types of soil, and withstand both cold winters and warm summers, with not one, but thousands of different varieties. So, why after being shipped 3, or 4, or 6 thousand miles away are bananas still cheaper than apples grown a few blocks away? The answer is, largely: the container. The story of the banana and 90% of everything we buy is that of the container ship, and how it forever changed the global economy. But first, let’s rewind. There are many ways to get goods from one place to another. Planes are fast, trucks are precise, and trains are efficient. But water is by far the cheapest. There are no roads to build, or intersections to stop at, and once a ship starts moving, it requires very little attention. Some of the biggest container ships in the world are manned by just 13 crew members. And companies like Rolls-Royce are developing self-driving versions as we speak. The problem, until recently, was moving cargo onto and off of the ship, which often took even more time than actually sailing. That’s because workers had to lift, carry, and drag everything from barrels, to crates, and heavy bags. Not so fun. And not very fast. A journey from New York to Europe, for example, might only take 12 days, but loading and unloading would take another 7. That’s 7 full days it could’ve spent delivering more cargo. Therefore, 7 full days added to the cost of shipping. Port fees, dock workers, and their equipment accounted for 60-75% of the cost of shipping. So, by the time a product reached our shelves, its price would have to be raised an average 12% to make up for it. But everything changed with the container. Companies realized they weren’t in the business of shipping bananas, or cars, or phones, They were in the business of… shipping. What’s inside the box shouldn’t matter, their job is generic, efficient transportation. In fact, today, crew members don’t even know most of what they’re carrying. If shipping companies could take everything and put it in a single size box, they could turn thousands of individual problems into just one: How to move a known object from one place to another as quickly as possible. If you’re a longshoreman, this is your worst nightmare. Your job, and in many cases, whole coastal economies, were now based on a repetitive, low-skill, and easily automated task. Unions, of course, fought back. At one point, a workers’ strike lasted 83 days. But the universal law is money finds a way. One company calculated that shortening the time required to lift a container by a single second would save $4,000 per ship, per year. And they wouldn’t be saving seconds, or minutes, or even hours, but days. Containers lowered the cost of insurance, made theft nearly impossible, and allowed for goods to be easily moved between ship, rail, and truck. The container was inevitable. The only question was which one. Four separate standards organizations, of course, had… four separate answers, but we’ll fast forward years of fascinating debate and just say, The world decided on these iconic 20 and 40 feet boxes you now see at every port in every country. Today, ports are filled not with workers, but giant cranes which move containers in and out of ships in the most efficient order possible. And ships spend most of their time in motion. The challenge is keeping containers full. The ideal route goes from A to B, where it loads new cargo for its return back to A. But this isn’t always possible. China, for example, has both high exports and imports. Problem is, its manufactured goods are sent out in container ships. But the raw materials it imports to make them arrive in bulk cargo ships. As a result, roughly 60% of containers shipped from Asia to North America return empty. Australia is the opposite. It exports raw goods like iron, gold, and coal, but imports its products on container ships. Cruise ships survive by offering repositioning trips - cheaper fares for longer, one-way routes it uses to change regions. Container ships don’t have that luxury, But their schedules are so predictable that factories can manufacture goods as they need them, rather than storing large amounts of inventory. In other words, everything is cheap. And there’s a lot of it. Shipping costs are so low that they almost don’t matter. The only thing that does is labor. It’s this combination of low wages, trivial shipping costs, and tight planning which turn the banana into the perfect consumer product. It thrives not despite its limitations but because of them. The journey begins in Ecuador, the world’s number one banana exporter. Thousands of plantations produce 2 billion dollars worth of the fruit every year. Bananas are picked while still green, in the first of seven stages. And immediately, the clock starts ticking. Because once a banana begins to ripen, the process is irreversible. Worse, a single banana ripening will trigger all those around it. So, everything that happens next is carefully planned to prevent that. First, imperfect bananas are sold locally or fed to livestock. The rest are packed in special containers called reefers, which keep them at a controlled 55.94 degrees Fahrenheit. Before being loaded, reefers are sealed, so they won’t be exposed to open air until they reach their destination. Next, they’re transported, usually by truck, to the dock, where they’re loaded 40 or 50 an hour onto ships. A large boat can carry 80 million bananas, a whole year’s supply for 600,000 Americans. And by traveling at only 18 or 19 knots, they save millions on their biggest expense: fuel. Ships may burn 400 tons of bunker fuel per day, which at current prices, amounts to nearly $200,000 in a single 24 hour period. Our ship, the Dole Pacific, makes deliveries from Ecuador to San Diego all year round. By the time it arrives, bananas have reached stage 2 - light green. They’re then moved to ripening rooms, where they’re sprayed with ethylene gas to trigger their ripening process. Once they reach stage 3, they’re ready for delivery to the grocery store. During this trip, they transition from 3 to 4, to 5, when they’re finally bought for less than a quarter. With a single, uniform variety, grown where labor is cheap, and sold in high-value consumer markets, bananas perfectly represent the efficiency of global shipping. The beauty of container ships is their ability to conveniently deliver goods regardless of where.
