The beepocalypse is on the cover of TIME, but it looks like managed honeybees will still pull through. Wild bees—and wild species in general—won’t be so lucky in a human-dominated planet.

I’ve written this week’s cover story for the magazine, on the growing threat to honeybees. You can read it (with a subscription) over here. The short version: beginning nearly a decade ago, honeybees started dying off at unusually and mysteriously high rates—this past winter, nearly one-third of U.S. honeybee colonies died or disappeared. At first this appeared due to something called colony collapse disorder (CCD); hives would be abandoned without warning, with bees seemingly leaving honey and intact wax behind. The apocalyptic nature of CCD—some people really thought the disappearance of the bees indicated that the Rapture was nigh—grabbed the public’s attention. More recently, beekeepers have been seeing fewer cases of CCD proper, but honeybees keep dying and bees keep collapsing. That’s bad for our food system—bees add at least $15 billion in crop value through pollination in the U.S. alone, and if colony losses keep up, those pollination demands may not be met and valuable crops like almonds could wither.

More than the bottom line for grocery stores, though, the honeybee’s plight alarms us because a species that we have tended and depended on for thousands of years is dying—and we don’t really know why. Tom Theobald, a beekeeper and blogger who has raised the alarm about CCD, put that fear this way: “The bees are just the beginning.”

But while we don’t now we exactly what causes CCD or why honeybees are dying in larger numbers, we do know the suspects: pesticides, including the newer class of neonicotinoids that seem to affect bees even at very low levels; biological threats like the vampiric Varroa mite; and the lack of nutrition thanks to monocultures of commodity crops like wheat and corn, which offer honeybees little in the way of the pollen they need to survive. Most likely, bee deaths are due to a mix of all of those menaces acting together—pesticides and lack of food might weaken honeybees, and pests like Varroa could finish them off, spreading diseases the bees don’t have the strength to resist. Unfortunately, that means there’s no simple way to save the honeybees either. Simply banning, say, neonicotinoids might take some of the pressure off honeybees, but most scientists agree it wouldn’t solve the problem. (And getting rid of neonicotinoids would have unpredictable consequences for agriculture—the pesticides were adopted in part because they are considered safer for mammals, including human beings.) Honeybees are suffering because we’ve created a world that is increasingly inhospitable to them.

Still, for all the alarm, honeybees are likely to pull through. As I point out in the magazine piece, beekeepers have mostly managed to replace lost colonies, though at a cost high enough that some long-time beekeepers are getting out of the business altogether. Beekeepers are buying new queens and splitting their hives, which cuts into productivity and honey production, but keeps their colony numbers high enough to so far meet pollination demands. They’re adding supplemental feed—often sugar or corn syrup—to compensate for the lack of wild forage. The scientific and agricultural community is engaged—see Monsanto’s recent honeybee summit, and the company’s work on a genetic weapon against the Varroa mite. Randy Oliver, a beekeeper and independent researcher, told me that he could see honeybees becoming a feedlot animal like pigs or chickens, bred and kept for one purpose and having their food brought to them, rather than foraging in the semi-wild way they live now. That sounds alarming—and it’s not something anyone in the beekeeping industry would like to see—but it’s also important to remember that honeybees themselves aren’t exactly natural, especially in North America, where they were imported by European settlers in the 17th century. As Hannah Nordhaus, the author of the great book A Beekeeper’s Lament, has written, honeybees have always been much more dependent on human beings than the other way around.

The reality is that honeybees are very useful to human beings, and species that are very useful to us—think domesticated animals and pets—tend to do OK in the increasingly human-dominated world we call the Anthropocene. But other wild species aren’t so lucky—and that includes the thousands of species of wild bees and other non-domesticated pollinators. Bumblebees have experienced recent and rapid population loss in the U.S., punctuated by a mass pesticide poisoning in Oregon this past June that led to the deaths of some 50,000 bumblebees. A 2006 report by the National Academies of Science concluded that the populations of many other wild pollinators—especially wild bees—was trending “demonstrably downward.” The threats are much the same ones faced by managed honeybees: pesticides, lack of wild forage, parasites and disease. The difference is that there are thousands of human beings who make it their business to care for and prop up the populations of honeybees. No one is doing the same thing for wild bees. The supposed beepocalypse is on the cover of TIME magazine, but “you don’t hear about the decline of hundreds of species of wild bees,” says Jennifer Sass, a senior scientist at the Natural Resources Defense Council.

That’s meant almost literally—we don’t hear them anymore. The plight of the bees illustrates our outsized influence on the this planet as we reshape it—consciously and not—to meet our immediate needs. But just because we have this power doesn’t mean we fully understand it, or our impact on our own world. We are a species that increasingly has omnipotence without omniscience. That’s a dangerous combination for the animals and plants that share this planet with us.  And eventually, it will be dangerous for us, too.
