Bees Disappear With Food Supply
Abstract
The number of bees worldwide has greatly decreased over the past seven decades. If this decrease continues, humans will experience a shortage in food due to fewer bees available to pollinate crops. To regrow and preserve the bee population in Iowa, agricultural changes must be made. The author of this proposition investigated various sources specifying elements of the conflict and formulating possible solutions. The resolution of this proposal is derived from that research and underlines how Iowa’s agricultural system can create healthier environments for pollinators. If the objectives of this proposal are accomplished, then immense progress will be made locally …show more content…
Richard Gill and Dr. Nigel Raine at Royal Holloway, researchers at the University of London, focuses on effects of multiple pesticides on bees (Dawson). The variation of chemicals mimics bee foraging habits, as bees normally visit multiple fields and are exposed to numerous pesticides. Bees were exposed to low levels of these pesticides for four weeks, and allowed to travel outside to collect pollen from real flowers, while a close eye was kept on their foraging behavior. Each bee received a radio frequency identification tag to monitor when they left and returned to the hive, and how long each outing lasted (Dawson). The study found that colonies exposed to neonicotinoids sent out more worker bees to collect pollen, but those worker bees were overall less affective at retrieving pollen. This lack of effective foraging limits colony growth …show more content…
