Investigating the mystery of disappearing bees by Nina Gotzmannova

One world famous theory is called Butterfly effect. The name came from the idea that if the butterfly will move its wings, it may cause a tornado in the opposite part of the world. It means that a small change in a big system can lead to large-scale phenomena. Something like that may be the mystery of disappearing bees. The cause is unknown, but the results are visible now and may be even dangerous. Bees are an important part of ecosystem. Farmers need them because only bees can do the pollination of crops. No fruits, no vegetables and no nuts can harvest without bees and being pollinated. Almost one-third of all food we eat is dependant on bees. But in 2006 something strange happened. Thousands, million and billion of those small, yellow and black striped animals, disappeared. No one is sure why and what to do with this unexpected situation. This phenomenon is called Colony Collapse Disorder (CCD). Symptoms are missing adult bees, honey present in colony, but surprisingly not attacked by other bees. Usually when a beehive is abandoned, other bees from other beehives rob the beehive and take away all the honey and bee pollen. Also one of the symptoms of CCD is presence of capped brood in colony, which is highly unusual, because adult bees wait until all eggs, larvae and pupae are hatched. The exact cause or mechanisms of CCD are unknown. It may be caused by malnutrition, pesticides, pathogens, viruses and diseases and lot of various reasons. But the question why so many bees disappeared in the same time in the same region without any visible reason is open. It's on scientists to investigate the mystery of disappearing bees and find a solution.
