To bee or not to bee. Is that really the question?

Alison Benjamin and Brian McCallum are two British reporters and amateur bee-keepers. Benjamin works for the British daily paper The Guardian. Their book "A world without bees" was published earlier this year, and deals with the mysterious mass deaths of honeybees all around the world, the so-called Colony Collapse Disorder (CCD). While some people belive that CCD doesn't really exist, for instance the current Wikipedia writer on the subject, others consider it a serious, global threat to bee-keeping. Benjamin and McCallum certainly belong to the latter camp, claiming that one third of US beehives and two-thirds of those in France have been wiped out by this mysterious condition. Most scientists seem to agree that CCD does exist, but so far no good explanation have been offered, at least none everyone agrees with. The two authors have interviewed researchers who blame pesticides, fungicides, the varroa mite, climate change, new viruses, or even mobile phones (that's a fringe position). Indeed, CCD could be a combination of several different factors. Israeli Acute Paralysis Virus (IAPV for short) is a prime suspect, but correlation is not necessarily the same thing as causation. Perhaps something in the environment is causing bees to loose their resistance to killer viruses?

The authors own position isn't entirely clear-cut, but their favorite hypothesis seem to be loss of genetic diversity. Most honeybees around the world apparently belong to the same group of Mediterranean subspecies, and the same goes for feral honeybees. These have interbred with wild honeybees, creating a situation in which the honeybee gene pool is virtually the same the world over. When the varroa mite struck, and developed resistance to pesticides, millions of honeybees quickly succumbed - their gene pool was too narrow to develop defenses against the parasite. Benjamin and McCallum therefore strongly supports conservation efforts aimed at preserving local subspecies of wild honeybees. They mention a particular attempt in Denmark, and describe the conflicts this has created between different factions of bee-keepers (the local bees are less productive than the Mediterranean breeds).

The bee-keeping industry seems to take the opposite position from that of the authors: the industry wants to genetically engineer a resilient, resistant and high-productive superbee. The authors fear that this will narrow the gene pool even more. What happens if (or when) the superbee is challenged by an equally resilient superbug?

The book then describes the chilling effects of a world without honeybees. If you think only the honey would disappear, think again! Many important crops are dependent on honeybees for pollination, including alfalfa, apples, almonds, cotton, citrus, soya beans, onions, broccoli, carrots, sunflowers, melons, blueberries, cherries and pumpkins. A world without bees would be a world without fruit, vegetables, juice, health food (the soya) or clothes (the cotton). Alfalfa is used as cattle feed, so a world without bees would also be a world without meat! To drive home the point, the two authors have visited California, where the highly profitable almond orchards are pollinated by honeybees from all over the United States, driven there on enormous trucks. If the honeybees would be wiped out by CCD, an entire industry would be gone. Already today, food prices are going up, due to ethanol production and other factors. CCD doesn't exactly help...

One solution to the crisis mentioned in the book is to use other insects as pollinators, including solitary bees and bumblebees. There are several research projects to that effect in the US. Meanwhile, habitat change have driven bumblebees to near-extinction in some areas, and other insects live too far away from agricultural land to be of much use. Once again, the authors feel that a more environmental-friendly policy is the bottom line.

Is the author's alarmist perspective true? No idea. Until I picked up this book, mostly by chance, I never even heard of CCD. (Of course, I have heard of the varroa mite.) However, Alison Benjamin and Brian McCallum have written an easy-to-read introduction to the issue, after talking to both scientists, migratory bee-keepers, almond growers, and even conspiracy theorists. I recommend the book, and call on everyone to continue researching the topic.
