If honeybees disappear, they’ll take some of our healthiest foods with them.
One day early last spring, Ed Olson’s life got much harder. A few weeks earlier, Olson, a commercial beekeeper, had delivered
200 of his 500 hives of honeybees to an almond orchard in Arbuckle, California. There, the honeybees would do their part
buzzing up and down rows of fragrant, flowering trees, helping to make California’s Central Valley the almond capital of the
universe. Like more than 100 of our food crops, almond trees will set fruit only if their flowers are cross-pollinated
between two different varieties. Like tiny farmworkers, honeybees carry the pollen from one tree to another as they forage.
Corn, wheat, rice and other grains rely on wind to spread their pollen. But honeybees pollinate much of the other stuff that
adds color to our plate and vitamins and antioxidants to our diet. They give us blueberries, apples, berries, cherries,
melons, grapefruit, avocados, squash, broccoli, carrots, onions, and more. If it lowers cholesterol, improves eyesight or
turbocharges the immune system, it was probably fertilized by a bee. A surprising amount of our well-being rests on those
tiny striped backs—and on the beekeepers who haul 2 million hives from crop to crop every year, renting them out for
When Olson had checked the Arbuckle hives the previous fall, they had been some of his strongest. The more bees in a hive,
the more pollinating power it has and the more a farmer will pay to lease it. But now, as Olson, with the lanky frame and
graying mustache of an Old West gunslinger, approached the first group of 24 colonies, he sensed something was off right
away. There weren’t many bees flying. It was a shimmering spring day in northern California and sunshine was glazing the soft
pink rows of budding almond trees: perfect flying weather for a honeybee. Olson cracked open the top of the first hive,
looked inside, and immediately his stomach sank with disappointment: no bees. It was a “dink”—the beekeeping term for a
colony that has died or dwindled. Just like that, he was out $200, the pollination fee for a strong hive.
Every commercial beekeeper finds a few dinks each spring, and Olson hoped this first hive had been an anomaly. Then he opened
the second hive and felt a little ill. Another dink. Then he opened the third and fourth and cursed to himself. By the time
he had opened all 24 colonies, he was in shock. There was plenty of honey in the hives, but the strong colonies that had
filled those boxes two months earlier had dwindled to almost nothing. In 25 years of professional beekeeping, he’d never seen
anything like it.
By anyone’s standards, Ed Olson is an excellent beekeeper (but he asked that his real name not be used). He feeds his bees
specially formulated, high-protein patties to keep their strength up and carefully monitors his hives for the presence of
diseases or parasites. He does everything right. Yet it seemed he had just been hit with the mysterious syndrome called
Colony Collapse Disorder, or CCD. In the winter of 2006-2007, CCD killed 32 percent of America’s honeybees. The next winter,
another 36 percent—more than a million hives—died.
“At first I was in denial,” Olson recalled. “Then I just felt weak and had to lean against my truck. A year’s hard work for
naught!” Olson wound up losing all 50 hives that had overwintered in one particular bee yard. That’s bad enough, but it pales
next to some operations. Adee Honey Farms of South Dakota, the largest beekeeping business in the country, lost 28,000 of its
70,000 hives. That’s about a billion bees gone missing. “It’s off the charts,” said Bret Adee. “It’s not a sustainable thing,
what’s happening now.”
At first it looked as though the United States was the sole sufferer of CCD, but the rest of the world quickly reported
losses also. “The situation for bees in Europe is no better than for bees in North America,” says Bernard Vaissière, a
pollination specialist with the French National Institute for Agricultural Research. A report issued last August by the
European Food Safety Authority estimates that the UK lost about 30 percent of its honeybees in 2007, while Italy lost 40 to
50 percent. Whatever is taking down bees has gone global.
A Sweet Deal
A hundred million years ago, as dinosaurs were cruising the savannahs and munching on ferns, pines and each other, bees and
plants hammered out the details of a deal that has been benefiting the rest of Earth’s denizens ever since. Until that time,
plants had used the wind to disseminate their pollen. But wind pollination is like Internet spam: you need to send a million
packets to find one receptive target. So sometime in the Cretaceous Period, one group of plants decided to start MapQuesting
each other instead. Why rely on the fickle wind when bugs could carry pollen directly between two plants? The trick was in
getting the couriers’ attention.
Until then, plants had spent several hundred million years trying to discourage animals from eating them. Toxins, spikes and
bitter-tasting leaves were the order of the day. Now, in a startling about-face, these new plants decided to make themselves
as appealing to animals as possible. They created beguiling shapes, colors and odors to snag passersby and offered up
delicious nectar punches free to all. When the bugs—and, later, birds, bats and butterflies—dropped by for their morning sip,
they’d get sticky pollen all over their hairy bodies and inadvertently deliver it to the next café. The flower was born. And
fruit was soon to follow.
Not many things out there want to be eaten. Talk to your basil all you want before you pick it; it’s still a bad day for the
basil. And if you’ve ever watched a hare tuck its ears back and turn on the afterburners, you know that the name of the game
of life is don’t get eaten. But not for the flowering plants: they eagerly offer nectar, pollen, fruits and nuts. They want
to keep us healthy and enthusiastic so that we’ll keep spreading their seeds around the planet. (And when it comes to
providing these services, we humans are the only species that’s been nearly as helpful as the bees.)
In evolution, this arrangement, where two species cooperate to the benefit of both, is called mutualism. And if you’ve ever
wondered why fruits and vegetables have so many compounds in them that keep us healthy, wonder no more. The plants that have
prospered are the ones that give animals (including us) what they need—antioxidants, vitamins and fiber that are critical to
our health. And the successful animals (including us) are the ones that thrive on what the plants have to offer.
What a fantastically beautiful arrangement. And what a shame it would be if we blew it by forgetting that honeybees have
always been a part of the team.
A Mystery Disease
We can’t say for certain that Olson’s bees had CCD, because we still don’t know what CCD is. We just know what it looks like,
and it looks like Ed Olson’s experience in the almonds that spring: hives that had been in superb condition suddenly
depopulate, with the adult bees disappearing from the hive until all that’s left is honeycomb filled with young bee larvae
Theories abound about what is causing CCD. Cell phones were an early suspect, based on nothing more than the results of one
mistranslated German study of cordless phones. Genetically modified crops were another rumored culprit, despite studies
showing that bees thrived on GMO corn. Neither of these proved true. Other causes that do seem to be associated with
collapsed colonies include pesticides, newly introduced viruses, fungi and poor colony nutrition. Congress has earmarked a
few million dollars for research to get to the heart of the problem, but the money has yet to start trickling out, and
results are years away. The bees might be able to wait that long, but we can’t.
“That’s the crux of CCD,” says Olson. “The bee population can eventually recover from disease losses, but American
agriculture depends upon gypsy beekeepers to provide the spark of pollination to start the engine of food production.” About
35 percent of the food we eat—$15 billion worth of produce in the United States and $215 billion worldwide—would not exist
without pollinators. Once we had thousands of native insects that provided all our pollination needs, but habitat destruction
and the ever-increasing size of industrial farms have put most of our crops out of reach of wild bugs. The only way to bring
pollination to these plants is to truck it in, and the honeybee is the only pollinator that will endure such a domesticated
lifestyle. Unfortunately, it remains to be seen how many beekeepers can endure their mounting economic losses. “Bees can be
replaced relatively quickly,” says Olson; “out-of-business beekeepers can’t.”
Turning the Tide
Despite the dire situation, there are some encouraging signs that we are starting to head in the right direction. Many
beekeepers believe pesticides known as neonicotinoids are responsible for CCD. In the United States, neonicotinoids are
widely used for everything from crops and golf courses to flea and termite control. Last August, the Natural Resources
Defense Council sued the EPA for refusing to disclose the studies done before approving a leading neonicotinoid in 2003. In
September, Italy became the fourth European country to ban neonicotinoids. So far, the evidence against the neonicotinoids is
mixed, but the fact that four countries would take such a radical step, simply to protect their honeybees, may mean that a
paradigm shift is under way. Beekeepers themselves are becoming more leery of conventional agriculture and are favoring
pollination contracts with organic farmers—a move that may encourage more farms to go organic.
But the number-one source of pesticides in beehives is the beekeepers themselves, who add pesticides to their hives in an
effort to control parasitic mites. That, too, is starting to change, as natural methods of mite treatment, as well as
mite-resistant strains of bees, become available. For years, organic beekeeping was rare because of the chemical mite
treatments; now it’s starting to look like it will one day be the rule, at least among hobbyists.
And oh the hobbyists! Beekeeping has been declining in popularity in the United States since World War II, but in the past
year, thanks to the attention brought by CCD, the ranks of new beekeepers have swelled to the point that beekeeping schools
have had to turn applicants away and beekeeping suppliers have run short of both gear and bees. “There is a tremendous
increase in the sale of beekeeping equipment,” says Steve Forrest, owner of Brushy Mountain Bee Farm in North Carolina, one
of the country’s leading suppliers. “It’s just staggering.” But that’s a good problem to have. It means that bees have
regained a place in our collective psyche that they haven’t occupied for generations. They are no longer icky insects to be
feared for their stingers (most stinging is done by yellow jackets) and are, once again, our ancient partners in the practice
of growing good food.
You could take Bee Movie as a sign that we’re starting to appreciate bees, but that movie didn’t even get the gender right.
Sorry, Jerry, but 99 percent of the bees in a hive—and all of the workers—are female. One sign that we are on the right track
came when Häagen-Dazs announced that because 40 percent of its ice cream flavors wouldn’t exist without bees it was donating
$250,000 to honeybee research and launching a new flavor, Vanilla Honey Bee, to support the cause. The Almond Board of
California, too, has been extremely supportive. When the other fruit, nut and vegetable companies are ready to pony up, we’ll
know we’re on the road to ensuring the fertility of our farms and fields.
In the end, Ed Olson managed to save his almond farmer from ruin. He desperately called his beekeeper friends and finally
found one who had a few dozen hives that weren’t spoken for. Olson trucked these hives into the almond orchard. A stretch of
warm, sunny weather arrived just in time, the bees flew all day every day, and the grower managed to set a record crop. The
story was the same throughout the San Joaquin and Sacramento Valleys: the weather saved the almonds. There probably hadn’t
been enough bees to cover the need, but perfect conditions gave the available bees extra flying hours and they managed to
pollinate all the trees.
As the pollination starts this spring, beekeepers and almond growers alike are holding their collective breath. They know
that all it will take is a good storm or two to upset the balance and break the sweet deal.
