Researchers blame cell phones for decline in bee populations. A group of scientists from the British Bee Association have noticed a sharp decline in bee populations in the United Kingdom. As of 2009, bee populations dropped by 17 percent in the United Kingdom and nearly 30 percent within the United States per U.S. Department of Agriculture statistics. Scientists believe that parasitic mites known as varroa, agricultural pesticides, and climate change have caused the "colony collapse disorder" threatening bee populations and food supplies throughout the world. Bees pollinate 90% of commercial crops across the world. Bees have an estimated economic value of $12 billion dollars within the United States and $290 million within the United Kingdom.
Indian researchers at the Panjab University in Chandigarh also suspect cell phones contribute to the bee population's decline. The Panjab study indicated that a cell phone's electromagnetic field and radiation leaks have caused the bees to produce less honey. The study also found that the queen bee produced half of her typical amount of eggs, and the entire size of the hive was dramatically reduced after just fifteen minutes of exposure to cell phones per day.
The United Kingdom's Imperial College in London, England supports the Panjab study. Biologist Andrew Goldsworthy believes that a pigment identified as cryptochrome may be affected by the radiation and electromagnetic waves of cell phones. Goldsworthy stated that "animals, including insects, use cryptochrome for navigation" in a recent CNN interview. Goldsworthy furthered that bees and other animals use cryptochrome "to sense the direction of the earth's magnetic field and their ability to do this is compromised by radiation from [cell] phones and their bas stations. So basically bees do not find their way back to the hive."
Goldsworthy belives that changing the frequency of cell phone transmissions may assist in improving bee populations worldwide. Unfortunately, without more advanced studies, cell phone companies reject Goldworthy's claim.
