Believe it or not, you have a bee to thank for every one in three bites of food you eat. Honey bees — wild and domestic — perform about 80 percent of all pollination worldwide. A single bee colony can pollinate 300 million flowers each day. Grains are primarily pollinated by the wind, but fruits, nuts and vegetables are pollinated by bees. Seventy out of the top 100 human food crops — which supply about 90 percent of the world’s nutrition — are pollinated by bees. What’s Killing the Bees — and Why It Matters Worldwide bee colony collapse is not as big a mystery as the chemical industry claims. The systemic nature of the problem makes it complex, but not impenetrable. Scientists know that bees are dying from a variety of factors—pesticides, drought, habitat destruction, nutrition deficit, air pollution, global warming and more. Many of these causes are interrelated. The bottom line is that we know humans are largely responsible for the two most prominent causes: pesticides and habitat loss. Worker bees (females) live about six weeks in summer and several months in the winter. Colonies produce new worker bees continuously during the spring and summer, and then reproduction slows during the winter. Typically, a bee hive or colony will decline by 5-10 percent over the winter, and replace those lost bees in the spring. In a bad year, a bee colony might lose 15-20 percent of its bees. In the U.S., winter losses have commonly reached 30-50 percent, in some cases more. In 2006, David Hackenberg — a bee keeper for 42 years — reported a 90 percent die-off among his 3,000 hives. U.S. National Agricultural Statistics show a honey bee decline from about 6 million hives in 1947 to 2.4 million hives in 2008, a 60 percent reduction. The number of working bee colonies per hectare provides a critical metric of crop health. In the U.S. — among crops that require bee pollination — the number of bee colonies per hectare has declined by 90 percent since 1962. The bees cannot keep pace with the winter die-off rates and habitat loss. Solutions That Save the Bees Common sense actions can restore and protect the world’s bees. Here’s a strong start: Ban the seven most dangerous pesticides. Protect pollinator health by preserving wild habitat. Restore ecological agriculture. Ecological farming is the overarching new policy trend that will stabilize human food production, preserve wild habitats, and protect the bees. The nation of Bhutan has led the world in adopting a 100 percent organic farming policy. Mexico has banned genetically modified corn to protect its native corn varieties. Eight European countries have banned genetically modified crops and Hungary has burned more than 1,000 acres of corn contaminated with genetically modified varieties. In India, scientist Vandana Shiva and a network of small farmers have built an organic farming resistance to industrial agriculture over two decades. Ecological, organic farming is nothing new. It is the way most farming has been done throughout human history. Ecological farming resists insect damage by avoiding large monocrops and preserving ecosystem diversity. Ecological farming restores soil nutrients with natural composting systems, avoids soil loss from wind and water erosion, and avoids pesticides and chemical fertilizers. By restoring bee populations and healthier bees, ecological agriculture improves pollination, which in turn improves crop yields. Ecological farming takes advantage of the natural ecosystem services, water filtration, pollination, oxygen production, and disease and pest control. Organic farmers have advocated better research and funding by industry, government, farmers, and the public to develop organic farming techniques, improve food production, and maintain ecological health. The revolution in farming would promote equitable diets around the world and support crops primarily for human consumption, avoiding crops for animal food and biofuels.
