The History of Honey — The Food That Never Dies — Transcript
Full transcript
- 0:00In 1922, archaeologist Howard Carter
- 0:03broke through a sealed doorway in
- 0:05[music] the Valley of the Kings near
- 0:06Luxor, Egypt. Inside the tomb of the
- 0:09pharaoh Tutankhamun, he found gold,
- 0:12jewels, and furniture untouched for over
- 0:143,000 years. But among all that
- 0:17treasure, his team found something
- 0:19stranger. Sealed inside alabaster jars,
- 0:22buried beside a dead king as if it were
- 0:25as precious as gold, was honey. And when
- 0:28they opened those jars, the honey was
- 0:30still perfectly edible. 3,000 years old,
- 0:33[music] and you could have spread it on
- 0:35toast. Every other food on the planet
- 0:37rots. Bread molds. Meat decays. Fruit
- 0:41turns to mush within weeks. But honey
- 0:44just sits there, centuries passing,
- 0:46empires collapsing around it, and it
- 0:49refuses to go bad. So, how does a
- 0:51substance made by insects [music]
- 0:53outlast entire civilizations? And how
- 0:56did this sticky golden liquid become one
- 0:59of the most valued [music] substances in
- 1:01human history?
- 1:02That answer starts long before the
- 1:04pharaohs.
- 1:06Long before Egypt even existed as a
- 1:08civilization. In 1921,
- 1:11a year before Carter found Tutankhamun's
- 1:13tomb, a group of researchers exploring a
- 1:16limestone cave [music] near Valencia,
- 1:18Spain, found something painted on the
- 1:21rock wall.
- 1:21>> [music]
- 1:22>> The painting showed a human figure
- 1:23clinging to the side of a cliff,
- 1:25reaching into a hole in the rock face,
- 1:27while a swarm of bees circled around
- 1:29them. In their other hand, they held a
- 1:32basket. They were collecting honeycomb,
- 1:34and they had clearly climbed a very long
- 1:36way to get it. That cave painting, found
- 1:39at a site called Cueva de la Araña,
- 1:42which translates to cave of the spider,
- 1:44is roughly 8,000 [music]
- 1:46years old. It is one of the earliest
- 1:48known depictions of humans interacting
- 1:50with bees.
- 1:51And it [music] tells us something
- 1:53important. Before we had agriculture,
- 1:55before we had writing, before we had
- 1:57metal tools, or pottery, or permanent
- 2:00settlements, we were already risking
- 2:02[music] our lives climbing cliff faces
- 2:04for honey. Similar rock art has been
- 2:06found in Southern Africa, in India, and
- 2:09in Australia.
- 2:11Across every continent [music] where
- 2:12bees existed, early humans figured out
- 2:15the same thing independently. Whatever
- 2:17was inside those hives was worth the
- 2:20pain of getting stung dozens, sometimes
- 2:23hundreds, of times.
- 2:24And humans were not species that
- 2:27recognized honey's [music] value. Across
- 2:29sub-Saharan Africa, a small brown bird
- 2:32called the greater honeyguide developed
- 2:34one of the strangest partnerships in the
- 2:36animal kingdom. A partnership that
- 2:38lasted tens of thousands of years. The
- 2:40bird would locate a wild beehive high in
- 2:43a tree, or inside a rock crevice. Then
- 2:45it would deliberately seek out a human.
- 2:47It would call [music] out with a
- 2:49specific chattering sound, flutter from
- 2:51branch to branch, and lead the person
- 2:53directly to the hive. The human would
- 2:56follow, build a fire, use the smoke to
- 2:59calm the bees, crack open the hive, and
- 3:02[music] take the honey.
- 3:03Then they would leave the wax and larvae
- 3:05behind for the bird.
- 3:07This was [music] not trained behavior.
- 3:09It was a relationship that evolved
- 3:11through natural selection over an
- 3:13enormous span of time [music] between
- 3:15two completely different species built
- 3:17entirely around one substance. Honey was
- 3:20so valuable that it literally shaped the
- 3:22evolution of another animal. For early
- 3:25humans, honey was quite literally
- 3:27irreplaceable. It was the only
- 3:29concentrated source of sweetness
- 3:31available anywhere in the natural world.
- 3:34Ripe [music] fruit offered some sugar,
- 3:36but it was seasonal, unpredictable, and
- 3:39diluted with water and fiber. Roots and
- 3:42tubers provided starch that the body
- 3:44could convert to glucose, but the
- 3:46process [music]
- 3:47was slow and inefficient. Honey was
- 3:49different. It delivered pure,
- 3:51concentrated, immediately available
- 3:54energy in a compact package that did not
- 3:56spoil. It could be found year-round in
- 3:59tropical and temperate climates, and it
- 4:01stored safely for months [music] without
- 4:03any preservation effort. It provided an
- 4:06incredibly dense burst of [music]
- 4:07calories, and the effort required to
- 4:09harvest it, climbing trees and cliff
- 4:12faces, enduring hundreds of stings,
- 4:14smoking out aggressive colonies,
- 4:16>> [music]
- 4:16>> was worth every second of pain.
- 4:19Anthropologists believe that honey may
- 4:21have played a direct role in human brain
- 4:23development. Our brains consume [music]
- 4:25roughly 20% of our total daily caloric
- 4:27intake, despite making up only about 2%
- 4:30[music] of our body weight. The glucose
- 4:32in honey would have been one of the most
- 4:34efficient fuel sources available to
- 4:36early hominids. Some researchers have
- 4:39even proposed that reliable access to
- 4:41honey helped push our ancestors toward
- 4:44larger, more energy-demanding brains
- 4:47over hundreds of thousands of years. If
- 4:49that theory holds up, honey did not just
- 4:52feed us. It may have helped make us who
- 4:54we are. But collecting wild honey was
- 4:56dangerous and unpredictable work. You
- 4:59had to find the hive first, then figure
- 5:01out how to reach it, then endure the
- 5:04fury of thousands of defensive bees. And
- 5:06at some [music] point, someone figured
- 5:08out there had to be a better way. The
- 5:10ancient Egyptians were the ones who
- 5:12cracked it roughly 4,500 [music]
- 5:15years ago. Along the fertile banks of
- 5:17the Nile River, Egyptian beekeepers
- 5:19built cylindrical [music] clay hives,
- 5:21stacking them horizontally in rows that
- 5:23looked almost like wine racks or clay
- 5:25pipes. These hives were designed to
- 5:28mimic the hollow logs and rock crevices
- 5:30[music]
- 5:30where wild bees naturally nested, and
- 5:33the bees moved in willingly.
- 5:35What made the Egyptian approach
- 5:37remarkable was its scale and
- 5:39sophistication. Some beekeepers loaded
- 5:41their hives onto barges [music] and
- 5:43floated them up and down the Nile,
- 5:45following the seasonal bloom of
- 5:47wildflowers, so their bees always had
- 5:49fresh pollen to work with. This was
- 5:51organized, deliberate, commercial
- 5:54beekeeping, [music] and it was happening
- 5:56more than 2,000 years before the Roman
- 5:58Empire existed. Honey in Egypt was not
- 6:01just food. It operated as currency,
- 6:04medicine, and sacred offering all at
- 6:06once.
- 6:07Workers at construction sites, including
- 6:09the laborers who built the Great
- 6:11Pyramids at Giza, were sometimes paid in
- 6:13jars of honey. Egyptian physicians used
- 6:16it to treat wounds, mixing it with
- 6:17[music] animal grease and plant fibers
- 6:20to create bandages that modern
- 6:21researchers have confirmed were
- 6:23surprisingly effective. Medical texts,
- 6:25[music] written on papyrus scrolls, some
- 6:28dating back to roughly 1,500 years
- 6:30before the common [music] era, list
- 6:32honey as an ingredient in over 500
- 6:35different remedies. They prescribed
- 6:36[music] it for eye infections, stomach
- 6:39ailments, burns, skin diseases, and
- 6:41surgical [music] wounds. And here is the
- 6:43thing that gets you. Modern science has
- 6:46validated many of these treatments.
- 6:48Honey has genuine, measurable
- 6:50antibacterial properties. The Egyptians
- 6:53figured this out through trial, error,
- 6:55and observation, thousands of years
- 6:58before anyone understood what a
- 6:59bacterium even was. Then, there was the
- 7:02religious dimension. Egyptians offered
- 7:05jars of honey to their gods,
- 7:07particularly to Min, the god of
- 7:09fertility, and to Ra, the sun god. The
- 7:12bee itself became a royal symbol, woven
- 7:15into the fabric of Egyptian identity.
- 7:17The pharaoh's formal title [music]
- 7:19included the phrase, "He of the sedge
- 7:21and the bee," linking the ruler of all
- 7:24Egypt directly to this tiny insect. When
- 7:27a pharaoh died, honey was placed in the
- 7:29burial tomb alongside [music] gold,
- 7:32precious stones, and weapons, because
- 7:34the Egyptians believed the afterlife
- 7:36required sustenance. And if you [music]
- 7:38were going to eat for eternity, you
- 7:40wanted something that would last
- 7:42forever.
- 7:43>> [music]
- 7:43>> As it turns out, they chose the one food
- 7:45on Earth that actually could. Egypt was
- 7:48far from the only ancient civilization
- 7:51captivated [music] by honey. Travel east
- 7:53to ancient India, and honey appears
- 7:55throughout the Vedas, sacred Hindu texts
- 7:58dating back roughly 3,000 years.
- 8:01Ayurvedic [music] practitioners
- 8:03prescribed honey for digestive problems,
- 8:05respiratory infections, and wound care.
- 8:08In Hindu mythology, [music] the god
- 8:10Vishnu was often depicted as a bee
- 8:13resting on a lotus flower, and the god
- 8:15Krishna was frequently associated with
- 8:18the color of dark honey. Travel further
- 8:20east to China, and honey shows up in
- 8:22medical texts from the Han Dynasty,
- 8:25roughly 2,000 years ago, recommended as
- 8:27[music] a treatment for fatigue, chronic
- 8:29pain, and poisoning. The legendary
- 8:32Chinese physician Shen Nong reportedly
- 8:34classified honey as a superior medicine,
- 8:37[music] meaning it could be taken
- 8:39long-term without harmful side effects.
- 8:41But, it was in ancient Greece where the
- 8:43cultural obsession with honey reached
- 8:45its peak. The Greeks believed bees were
- 8:48messengers from the gods. They called
- 8:50honey the food of the divine, and
- 8:51associated it with wisdom, [music]
- 8:53eloquence, and immortality. The Oracle
- 8:56at Delphi, the most important religious
- 8:58site in the entire Greek world, was
- 9:00sometimes referred to as the bee.
- 9:03Priestesses who served at the temple
- 9:05were called melissae, a word that
- 9:07literally translates to honeybees.
- 9:10Newborn babies were anointed with honey.
- 9:12The dead [music] were sometimes
- 9:13preserved in it. Honey touched every
- 9:15stage of a Greek life. Aristotle, one of
- 9:19the greatest thinkers in human history,
- 9:21spent years carefully observing bee
- 9:23colonies and documenting [music] their
- 9:25behavior. His observations were not
- 9:27always accurate. He believed the queen
- 9:29bee was actually a male king, for
- 9:32example. But, his writings represented
- 9:34one of the earliest attempts at
- 9:36systematic biological study, and the
- 9:38fact that he chose bees as his subject
- 9:41[music] tells you something about how
- 9:43central they were to Greek intellectual
- 9:45life. Athletes competing in the ancient
- 9:48Olympic Games ate honey before their
- 9:50events as an energy source, a practice
- 9:52that modern sports nutrition has
- 9:54essentially validated. Soldiers carried
- 9:57honeycombs into battle, and Hippocrates,
- 9:59the father of Western [music] medicine,
- 10:01prescribed honey for fevers, wounds, and
- 10:04ulcers. When Hippocrates wrote that
- 10:06honey cleans sores and ulcers, [music]
- 10:08softens hard ulcers of the lips, and
- 10:11heals running sores, he was writing a
- 10:13medical recommendation that wound care
- 10:16specialists in modern hospitals would
- 10:18still largely agree with [music] today.
- 10:20The Romans inherited the Greek obsession
- 10:22with honey, and being Romans, they
- 10:25industrialized it. Wealthy Roman estates
- 10:27maintained large apiaries with hundreds
- 10:30of hives. Beekeeping became a respected
- 10:32branch of agriculture, written [music]
- 10:34about by scholars and practiced by
- 10:36landowners across the empire. Virgil,
- 10:39arguably Rome's greatest poet, devoted
- 10:42the entire fourth book of his Georgics
- 10:44to bees. He described their colonies
- 10:46with a reverence that bordered on
- 10:48worship, comparing the hive to an ideal
- 10:50society, disciplined, productive, and
- 10:53selflessly devoted to the common good.
- 10:55[music]
- 10:56Roman soldiers used honey to preserve
- 10:58fruit during long military campaigns.
- 11:01Wealthy Romans poured it over roasted
- 11:03game, mixed it into spiced wine, and
- 11:06used it as the primary sweetener in
- 11:07virtually all of their cooking. Refined
- 11:10[music] sugar from sugarcane would not
- 11:12arrive in Europe for another thousand
- 11:14years. Until then, honey was the only
- 11:17option. And throughout all of this,
- 11:19across thousands of years and dozens of
- 11:21civilizations, one strange fact remained
- 11:24constant. Honey never [music] spoiled.
- 11:27Not in Egyptian tombs. Not in Greek
- 11:29amphoras sealed with wax. Not in Roman
- 11:32cellars. People noticed this. People
- 11:35relied on it, but nobody could explain
- 11:37why.
- 11:38That explanation [music] would take
- 11:40roughly 2,000 more years and the
- 11:42invention of modern chemistry. The
- 11:44science behind honey's bizarre
- 11:46immortality comes down to four [music]
- 11:48properties working together and each one
- 11:50on its own would be impressive.
- 11:52Combined, they make honey nearly
- 11:54indestructible. First, moisture content.
- 11:57Honey contains less than [music] 18%
- 12:00water. That number is critical because
- 12:03bacteria and microorganisms need water
- 12:06to survive and reproduce. They
- 12:08physically cannot grow in an environment
- 12:10that [music] dry. When bees make honey,
- 12:12they start with flower nectar, which is
- 12:15roughly 80% water. They pass the nectar
- 12:18from bee to bee inside the hive, each
- 12:21one adding digestive [music] enzymes and
- 12:23fanning their wings to evaporate
- 12:25moisture. By the time the process
- 12:27finishes and the bees seal the cell with
- 12:29a wax cap, the water content has dropped
- 12:32below the threshold where virtually any
- 12:34microorganism can survive. Trying to
- 12:36grow bacteria in honey
- 12:38>> [music]
- 12:38>> is like trying to grow a garden in the
- 12:40Sahara. Second, acidity. Honey's pH sits
- 12:44between roughly 3 and 4.5, which [music]
- 12:47puts it in the same range as vinegar or
- 12:49grapefruit juice. That level of acidity
- 12:52creates a hostile environment for the
- 12:54vast majority of bacteria and pathogens,
- 12:57which prefer neutral conditions close to
- 12:59a pH of 7. Between the extreme dryness
- 13:02and the acid, [music]
- 13:04honey is already one of the least
- 13:05welcoming environments in the natural
- 13:07world. But the bees added a third line
- 13:10of defense. During the honey making
- 13:12process, bees introduce an enzyme called
- 13:15[music] glucose oxidase from their
- 13:17salivary glands. This enzyme serves a
- 13:20very specific purpose. When it breaks
- 13:23down [music] the glucose in honey, it
- 13:24produces two chemical byproducts. The
- 13:27first is gluconic acid, which further
- 13:30lowers the pH and makes the honey even
- 13:32more acidic. The second is hydrogen
- 13:35peroxide.
- 13:36>> [music]
- 13:36>> Yes, the same hydrogen peroxide you
- 13:39might pour on a scraped knee to prevent
- 13:41infection. Honey is quietly and
- 13:43continuously producing its own
- 13:46antiseptic. Not in large enough
- 13:48quantities [music] to harm a person
- 13:50eating it, but in exactly the right
- 13:52concentration to kill bacteria on
- 13:54contact. This is the reason those
- 13:56ancient Egyptian wound treatments
- 13:58actually [music] worked. The honey was
- 14:00slowly and steadily sterilizing the
- 14:02wound from the inside. And then there is
- 14:04the fourth property, which ties the
- 14:06whole system together. Honey is
- 14:08hygroscopic. That means it actively
- 14:11absorbs and pulls [music] moisture from
- 14:13its surroundings. If a bacterium somehow
- 14:15lands on the surface of honey, the honey
- 14:18draws water [music] directly out of the
- 14:19bacterial cell through a process called
- 14:22osmotic pressure. The bacterium
- 14:25essentially dehydrates and dies [music]
- 14:27on contact. It is a passive, automatic
- 14:30defense system that requires no
- 14:32maintenance, no refrigeration, no
- 14:34preservatives, and no human
- 14:36intervention. Put all four together, low
- 14:39water content, high acidity, continuous
- 14:43hydrogen peroxide production,
- 14:45and osmotic [music] dehydration of any
- 14:48invading microorganism, and you have a
- 14:50substance that is hostile to virtually
- 14:52every form of microbial life on Earth.
- 14:55As long as the container stays sealed
- 14:57and no outside moisture gets in, honey
- 15:00will [music] remain unchanged for
- 15:02centuries, for millennia, for longer
- 15:04than any civilization in recorded
- 15:06history has lasted. Modern medicine has
- 15:09circled back to what the Egyptians
- 15:10[music] and Greeks knew intuitively. In
- 15:13hospitals across the world, medical
- 15:15grade honey is now used to treat chronic
- 15:17wounds, burns, and surgical incisions. A
- 15:21specific variety called manuka honey
- 15:23produced by bees in New Zealand that
- 15:25feed on the Manuka bush has become
- 15:28particularly valued [music] because it
- 15:30contains an additional antibacterial
- 15:32compound called methylglyoxal
- 15:35that works even when the hydrogen
- 15:37peroxide is neutralized. [music]
- 15:39Researchers have found that Manuka honey
- 15:41can kill antibiotic-resistant bacteria
- 15:44like MRSA, the superbug that terrorizes
- 15:47[music] modern hospitals. Think about
- 15:49that. A substance produced by insects
- 15:52using a process that has not changed in
- 15:54millions of years is now being deployed
- 15:56[music] against bacteria that have
- 15:58evolved to resist our most advanced
- 16:00pharmaceuticals. We spent decades
- 16:02building synthetic antibiotics. Some of
- 16:05the toughest infections we face respond
- 16:08to something bees figured out long
- 16:10before we existed, but despite all of
- 16:12its chemical armor, honey does have one
- 16:15vulnerability.
- 16:16Human carelessness. Add water, leave the
- 16:19lid off in a humid kitchen, or
- 16:22repeatedly dip a wet spoon into the jar,
- 16:25and you introduce [music] enough
- 16:26moisture for wild yeast to take hold.
- 16:29That yeast ferments the sugars, and the
- 16:31honey [music] transforms into something
- 16:33else entirely, which is actually how
- 16:35humans stumbled [music] into one of the
- 16:37oldest alcoholic beverages in history.
- 16:40Mead, [music] which is essentially
- 16:41fermented honey mixed with water, may
- 16:44predate both beer and wine. [music]
- 16:46Evidence of mead production has been
- 16:48found in pottery fragments from northern
- 16:50China dating back roughly 9,000 years,
- 16:54making it a candidate for the oldest
- 16:56intentionally produced [music] alcoholic
- 16:58drink in human history. The ancient
- 17:00Greeks drank it at festivals and
- 17:02rituals. Ethiopian culture developed a
- 17:04honey wine called tej that remains
- 17:07popular to this day. The Norse Vikings
- 17:09built an entire mythology around mead,
- 17:12believing that a magical brew called the
- 17:14mead of of
- 17:15which had been crafted by dwarves
- 17:17[music] from the blood of a murdered
- 17:18wise god named Kvasir, could grant
- 17:21wisdom, [music] eloquence, and creative
- 17:23inspiration to anyone who drank even a
- 17:26single sip. Viking warriors believed
- 17:28that the halls [music] of Valhalla
- 17:30flowed with endless mead served to them
- 17:32by Valkyries for all eternity. Across
- 17:35medieval England, Scandinavia, Poland,
- 17:38[music] and much of Eastern Europe, mead
- 17:41was the dominant alcoholic beverage for
- 17:43centuries, long before widespread
- 17:45[music]
- 17:45grape cultivation made wine accessible
- 17:48to anyone living north of the Alps. The
- 17:50English word honeymoon likely traces
- 17:53back to the medieval tradition of
- 17:54newlywed [music] couples drinking mead
- 17:56for an entire lunar cycle after their
- 17:58wedding,
- 17:59>> [music]
- 17:59>> a practice believed to promote fertility
- 18:02and good fortune. And it was medieval
- 18:04Christian monks who kept the art of
- 18:06beekeeping alive through the long
- 18:08centuries when much of the classical
- 18:10world's accumulated knowledge was being
- 18:13lost. Monasteries across Western Europe
- 18:16maintained extensive apiaries, though
- 18:18not primarily for honey.
- 18:21Their real motivation was beeswax.
- 18:23[music]
- 18:24The Catholic Church required pure
- 18:26beeswax candles for all religious
- 18:28services, [music]
- 18:29believing that beeswax produced by
- 18:31virgin worker bees was the only material
- 18:33holy enough to illuminate the altar.
- 18:36This doctrinal requirement created
- 18:38[music] enormous demand, and monasteries
- 18:40became the beekeeping centers of the
- 18:42Western world for nearly [music] a
- 18:43thousand years. The honey was treated
- 18:46almost as a secondary benefit. Monks
- 18:48used it for cooking, for brewing mead to
- 18:51sell at market, and for [music]
- 18:52preparing medicines, continuing healing
- 18:54traditions that stretched back unbroken
- 18:57to [music] the ancient Egyptians. For
- 18:58centuries, the basic practice of
- 19:00beekeeping changed [music] very little.
- 19:03Beekeepers used woven straw hives called
- 19:06skeps, and harvesting honey usually
- 19:08meant killing the colony
- 19:10>> [music]
- 19:10>> or destroying most of the honeycomb. It
- 19:12was wasteful and clumsy, but nobody had
- 19:15developed a better method. Then, in
- 19:171851, a minister [music] and amateur
- 19:20naturalist from Philadelphia named
- 19:22Lorenzo Lorraine Langstroth made a
- 19:24discovery that transformed everything.
- 19:27While studying his own hives, Langstroth
- 19:30noticed something that other beekeepers
- 19:32had overlooked for thousands of years.
- 19:35Bees leave a very specific gap between
- 19:37their combs, roughly 3/8 of an inch. If
- 19:40the space is narrower than that, the
- 19:42bees seal it shut with propolis, a
- 19:44sticky plant resin they collect. If the
- 19:47space is wider, they build extra comb to
- 19:50fill it in. But at exactly 3/8 of an
- 19:52inch, they leave the gap open and use it
- 19:55as a passageway. Langstroth called this
- 19:58principle [music] bee space, and he
- 20:00realized he could exploit it. He
- 20:02designed a wooden hive with removable
- 20:04frames, each spaced precisely 3/8 of an
- 20:07inch apart. [music]
- 20:08Beekeepers could now pull out individual
- 20:10frames, inspect the colony for disease,
- 20:13harvest honey from specific combs, and
- 20:16slide the frames back into place [music]
- 20:18without destroying anything. The bees
- 20:21would simply continue building on the
- 20:22existing foundation. [music]
- 20:24This single invention, the Langstroth
- 20:26movable frame hive, became the
- 20:29foundation of modern beekeeping
- 20:30worldwide.
- 20:32>> [music]
- 20:32>> Langstroth patented the design in 1852
- 20:35and published a book called The Hive and
- 20:37The Honey Bee that became the definitive
- 20:39[music]
- 20:40reference for beekeepers across the
- 20:41English-speaking world. Virtually every
- 20:44commercial beehive in operation today is
- 20:46still based on his original concept. His
- 20:49invention transformed beekeeping from a
- 20:51destructive [music]
- 20:52seasonal harvest into a sustainable,
- 20:54repeatable, scalable agricultural
- 20:57practice, and it made the mass
- 20:59production of honey possible for the
- 21:00very first time in human history. By the
- 21:03middle of the 20th century, commercial
- 21:05beekeeping had grown into a major global
- 21:08industry. The United States alone
- 21:10maintained millions of managed colonies.
- 21:13>> [music]
- 21:13>> Beekeepers loaded their hives onto
- 21:15flatbed trucks and drove them thousands
- 21:17of miles across the country, renting
- 21:19their bees out to farmers who
- 21:21desperately needed pollination [music]
- 21:22for almond orchards in California,
- 21:25blueberry fields in Maine, apple groves
- 21:27in Washington state, and dozens of other
- 21:29crops. The honey itself was almost
- 21:32secondary to this arrangement. The real
- 21:34money was in pollination services
- 21:36because without honey bees and the wild
- 21:39bees that assist them, roughly one out
- 21:41of every three bites of food we eat
- 21:43would simply cease to exist. And then,
- 21:46in the autumn of 2006,
- 21:49beekeepers across the eastern United
- 21:51States started reporting something
- 21:53terrifying. [music] They were opening
- 21:55their hives for routine inspections and
- 21:57finding them empty. Not dead, empty. The
- 22:01adult worker bees had vanished. The
- 22:03queen was still there, surrounded by a
- 22:05small cluster [music] of young bees and
- 22:07plenty of stored honey, but the adult
- 22:09foragers were gone. They had left the
- 22:12hive and never returned. Nobody could
- 22:14find the bodies. Nobody could explain
- 22:17where they went. [music] Within a single
- 22:19season, beekeepers lost roughly 30% of
- 22:22their managed [music] colonies. Some
- 22:24operations lost over 90%. Scientists
- 22:27named [music] it colony collapse
- 22:28disorder, and the search for a cause
- 22:31consumed years of research and millions
- 22:33of dollars in funding. What they
- 22:35eventually found was not a single
- 22:37smoking gun. It was a web of
- 22:39interconnected stresses, each one
- 22:42capable of weakening [music] a colony,
- 22:44and all of them hitting at once. A
- 22:46parasitic mite called Varroa destructor,
- 22:49originally from Asia, had spread to
- 22:51colonies across the globe. The mite
- 22:53feeds on the fat bodies of developing
- 22:55bee larvae and transmits viruses that
- 22:58the immune system of the entire
- 23:00hive. At the same time, a class of
- 23:03agricultural pesticides called
- 23:05neonicotinoids, [music]
- 23:07which had become the most widely used
- 23:09insecticides in the world, was found to
- 23:11impair bees' navigation and memory at
- 23:14doses too low to kill them outright. The
- 23:17bees could forage, but they could not
- 23:19find their way home. Meanwhile,
- 23:22monoculture farming was destroying
- 23:23[music]
- 23:24the wildflower diversity that bees
- 23:26depend on for balanced nutrition.
- 23:29Chronic transportation stress from being
- 23:31trucked across the country weakened
- 23:32immune systems further. Climate change
- 23:35disrupted the timing between flower
- 23:37blooms and bee emergence from winter
- 23:39dormancy.
- 23:41Colony collapse disorder was not one
- 23:43problem. It was everything colliding at
- 23:46once. [music] Decades of industrial
- 23:48agricultural practices slowly eroding
- 23:50bee health until the system finally
- 23:52buckled. The crisis has not fully
- 23:54resolved. Managed honeybee colony
- 23:57numbers in the United States have
- 23:59somewhat stabilized, but only because
- 24:01commercial beekeepers have adopted a
- 24:03brutal replacement strategy. They
- 24:05aggressively split their surviving hives
- 24:08each spring, dividing strong colonies
- 24:10into two or three smaller ones, and
- 24:12introducing new queens to rebuild
- 24:14population numbers before the next
- 24:16pollination season. It works on paper.
- 24:19Colony counts stay roughly stable from
- 24:22year to year.
- 24:23But the underlying health of the bee
- 24:25population
- 24:25>> [music]
- 24:25>> has not recovered. Beekeepers are
- 24:28running faster just to stay in the same
- 24:30place. Winter losses that would have
- 24:32been considered catastrophic 20 years
- 24:34ago are now treated as normal operating
- 24:37costs. Wild bee populations face a
- 24:40grimmer picture. Solitary bees,
- 24:43bumblebees, and the hundreds of native
- 24:45pollinator species that do not have
- 24:47human beekeepers artificially propping
- 24:49them up continue to decline [music]
- 24:51across North America, Europe, and parts
- 24:53of Asia. A A published by researchers in
- 24:56the United Kingdom found that 1/3
- 24:59[music] of wild bee and hoverfly species
- 25:01were in decline. Several bumblebee
- 25:03species [music] that were once common
- 25:05across the American Midwest have
- 25:07effectively vanished from large parts of
- 25:09their former range. The ecological
- 25:12stakes are enormous. Bees and other
- 25:14pollinators are responsible for the
- 25:16reproduction of roughly 70% of the crop
- 25:19species that feed 90% of the global
- 25:22human population. If pollinator
- 25:24populations collapse permanently, the
- 25:26consequences cascade through the entire
- 25:29food system, far beyond losing jars
- 25:31[music] of honey on grocery shelves. We
- 25:34are talking about almonds, apples,
- 25:36avocados, [music] blueberries, cherries,
- 25:39cucumbers, and dozens of other crops
- 25:41that depend on insect pollination to
- 25:43produce fruit. And those grocery shelves
- 25:46have their own separate crisis.
- 25:48Global demand for honey now far exceeds
- 25:51what bees can naturally produce. And the
- 25:54gap has been filled by widespread fraud.
- 25:56Independent laboratory testing has
- 25:58repeatedly found that a significant
- 26:01share of honey sold in international
- 26:03markets is adulterated [music]
- 26:04with cheap corn syrup, rice syrup, or
- 26:07beet sugar. Some products sold under
- 26:10honey labels contain no actual honey at
- 26:12all. In 2013,
- 26:14the United States Department of Justice
- 26:17brought criminal charges against two
- 26:19major importers for smuggling over $80
- 26:22million worth of Chinese honey into
- 26:25[music] the country through shell
- 26:26companies in other nations to evade
- 26:29tariffs. The honey had been
- 26:31ultra-filtered to strip out all pollen
- 26:33grains, making its geographic origin
- 26:36completely [music]
- 26:36untraceable. Some shipments were
- 26:38contaminated with chloramphenicol,
- 26:40[music] an antibiotic banned from food
- 26:42products in the United States. The
- 26:45investigation became known as Honeygate,
- 26:47and it exposed just how lucrative the
- 26:50global fake honey trade had become.
- 26:53There is a grim irony in all of this. A
- 26:56substance that has survived perfectly
- 26:57[music] intact for 3,000 years inside a
- 27:00sealed Egyptian tomb can be cheaply
- 27:02counterfeited with a jug of corn syrup
- 27:04[music]
- 27:04and a misleading label. But despite
- 27:07every threat, honey endures. It endures
- 27:11because it has always endured. Long
- 27:13before any human understood glucose
- 27:15[music] oxidase or osmotic pressure or
- 27:18hydrogen peroxide, people recognized
- 27:20that this golden [music] liquid was
- 27:22fundamentally different from every other
- 27:24food in nature. They watched bread grow
- 27:27mold and meat
- 27:28>> [music]
- 27:28>> turn rancid and milk go sour. And then
- 27:32they looked at a jar of honey sitting
- 27:34untouched [music] on a shelf, unchanged
- 27:36after months and years. And they treated
- 27:38it as something set apart from the
- 27:40ordinary [music] world. They did not
- 27:42have the vocabulary of chemistry. They
- 27:44did not know about [music] pH levels or
- 27:46water activity or enzymatic reactions.
- 27:50They just knew that honey lasted. And
- 27:52because it lasted, [music] they gave it
- 27:53to their gods.
- 27:55The Egyptians sealed it in tombs beside
- 27:57[music] their kings.
- 27:59The Greeks anointed their newborns with
- 28:00it and fed it to the dead. The Romans
- 28:03[music] built estates around the insects
- 28:05that produced it. Medieval monks shaped
- 28:07an entire economy [music] from the wax
- 28:09those insects left behind. And when a
- 28:11curious minister in Philadelphia
- 28:13measured the gap between honeycombs
- 28:15[music]
- 28:15and found it was exactly 3/8 of an inch,
- 28:19he accidentally unlocked an industry
- 28:21[music] that now helps feed the planet.
- 28:23Think about that for a second. A jar of
- 28:25honey sitting on your kitchen counter
- 28:27connects you backward through time to
- 28:29Howard Carter brushing dust off an
- 28:31alabaster jar in a pharaoh's tomb in
- 28:341922.
- 28:36Further back to a prehistoric human
- 28:38clinging to a cliff face in Spain 8,000
- 28:41years ago, bees swarming around their
- 28:43head, a basket clutched in one hand.
- 28:46Further still to a Greek athlete eating
- 28:48honeycomb before a foot race at the
- 28:50ancient Olympics. The same substance,
- 28:53the same chemistry, the same small
- 28:55insect doing the same quiet
- 28:57extraordinary work it has been doing for
- 29:00millions of years before any human
- 29:02civilization ever existed.
- 29:05Honey does not just survive across the
- 29:07centuries. It connects us to them.
- 29:10Backward through time, across languages,
- 29:13religions, revolutions to something
- 29:16older than farming, older than writing,
- 29:18older than virtually everything we have
- 29:20built. And the bees that make it
- 29:22possible are still out there right now,
- 29:24visiting flowers, fanning their wings
- 29:26inside dark hives, turning nectar into
- 29:29something that refuses to die.
- 29:31>> [music]
- 29:31>> Whether we protect them well enough to
- 29:32keep that chain unbroken is a question
