The humble honeybee has been inextricably linked to humankind since prehistoric times — at first we were drawn to this remarkable creature because of its sweet honey.

Honey is to a bee what electricity is for humans — energy. One teaspoon of honey weighing 21 grams contains 16 grams of sugar or 60 calories, and it took 12 bees their entire foraging lives, with a combined flying time of about 9,700 kilometres, to produce 21 grams of honey.

To understand the importance of honeybees consider that every third bite on your plate is a result of their primary role on the planet as pollinators, the most important group on Earth.

Honeybees contribute at least $47 billion a year to the North American economy by pollinating crops like almonds, apples, avocados, blueberries, broccoli, canola, carrot seeds, cherries, citrus, cranberries, cucumbers, grapes, lettuce, macadamias, melons, peaches, plums, pumpkins, onion seeds, squash, sunflowers, kiwis, tomatoes, zucchinis (to name a few); alfalfa and clover for the beef and dairy industries; cotton for our clothes; honey, candles and medicines.

Bees have been on the planet for more than 100 million years or about 14 times longer than the first human progenitor. Bees have a memory; they vote; they are being trained to count; and are helping people as an early detector of disease by sniffing skin and lung cancers, diabetes and tuberculosis.

The Red Cross estimates there are 80 million to 120 million landmines in 70 countries and 40,000 new landmines are being deployed weekly. Each year these brutal weapons of destruction maim tens of thousands of children. Researchers from the University of Montana are using bees to find TNT residue — the primary ingredients in landmines — while conducting surveys many miles away from the hive.

Many blue-chip corporations depend on the honeybees for their products.

A combination of factors has collided to create the perfect storm responsible for memory loss, appetite loss and autoimmune system collapse, resulting in the rapid decline in honeybee populations worldwide. Each year 2.3 billion kilograms of pesticides are applied globally. Many of them are neonicitinoids, a nerve poison that prevents acetylcholine from allowing neurons to communicate with each other and muscle tissue. In humans it would trigger Parkinson’s and Alzheimer’s.

Imidacloprid (one form of neonicitinoids) is manufactured by Bayer under the trade names of Gaucho and Pancho; it killed millions of bees in France before eventually being banned there, yet it’s still used widely throughout North America.

In 2008 researchers from Penn State University found 43 different pesticides in a Pennsylvania apple orchard. Many farmers combine or stack their chemicals to reduce applications costs; however, stacking chemicals is known to increase toxicity levels in some cases a thousand-fold.

Research from Europe showed that bees exposed to electromagnetic radiation from cellular towers made 21 per cent less honeycomb and that 36 per cent, taken a half mile from the hive, couldn’t navigate their way home.

In 2006 the honeybee genome was decoded and their genetics revealed only half as many genes for detoxification and immunity compared to other known insects. Scientists found specific “good” bacteria inside their stomachs and intestines crucial for fighting pathogens and digesting the silica casing around each pollen grain, providing access to its protein.

Bees evolved to feed on a wide assortment of pollens, but today we use them in monoculture fields. Pollens provide their only source of protein. Proteins grow eggs, larvae, brains and autoimmune systems.

The abnormally high temperatures of 2006 were likely the tipping point for bees in North America. The searing springtime temperatures during the onset of flowering are believed to have caused sterile pollen in many plants. Sterile pollen produces little if any protein.

Beekeepers around the globe are now feeding their hives a form of a protein shake with eggs, brewers yeast, pollen and honey and other special ingredients.

Clearly agriculture all around the world must reduce the levels in toxicity from pesticides, herbicide and miticides.

There is hope on the horizon because organics is the fastest growing sector in North America at $27 billion US a year — United States first lady Michelle Obama has an organic garden on the White House lawn with two honeybee hives close by.

Each of us can help by purchasing organic foods and cottons, and supporting local beekeepers by buying organic honey. Do not use herbicides, pesticides or miticides in your yard. Plant a wide variety of native yellow and blue flowers and participate by helping scientists in Nature Watch’s program ( www.icewatch.ca/english/plantwatch/).

Without the bees we cannot survive.
