Are Cellphones Killing Honeybees? (16th May, 2011)It’s a fact that the world honeybee population is in decline around the globe. Scientists have various possible explanations as to why, including cold weather, genetically-modified crops, and viruses. They have now added mobile phones to the list of possible bee killers. Swiss researchers have done a study on what is known as Colony Collapse Disorder, a phenomenon in which worker bees desert the hive, never to return. This situation leads to the end of the colony because the queen bee runs out of food. Lead researcher Daniel Favre says his study shows a relationship between the growing use of cellphones and declining bee populations. Favre notes that earlier studies failed to find any such link and thus accepts his findings are “highly controversial”. Favre’s study analyzed bee sounds in five healthy beehives in two different places in Switzerland. He recorded the bees' sounds with mobile phones in the hive. The bees were monitored when the mobile phones were active and inactive. Scientists analyzed the sounds of the bees and discovered they weren't disturbed by mobile phones that were inactive or on standby. However, active and ringing cellphones confused the bees and caused them to fly away from and leave the hive. The study says "the behavior of the bees remained perturbed for up to 12 hours after the end of the prolonged mobile phone communication," Favre writes. "This observation means that honeybees are sensitive to…electromagnetic fields generated by the mobile telephones."
WARM-UPS1. HONEYBEES: Walk around the class and talk to other students about honeybees. Change partners often. Sit with your first partner(s) and share your findings. 2. CHAT: In pairs / groups, decide which of these topics or words from the article are most interesting and which are most boring.
