Britain could face a food crisis due to population decline of honey bees.
Bees as pollinators of plants «responsible» for every third piece of our food. Consequently, if the insects disappear, pollinating certain species of flora, farmers will not be able to grow crops such as apples and pumpkin. Scientists also fear that a lack of pollinating insects can cause what is not properly pollinated species can not grow. By the way, in his time, Albert Einstein predicted that if bees disappear from the face of the earth, a man can live after only four years.
Previous studies have shown that the bee population is declining faster in England than anywhere else in Europe over the last twenty years, the number of bees decreased is two-fold. If in 1965 in England was 182 thousand. Colonies, then by 1985 th 179 thousand of them left., And today — only 83 thousand. Butterflies and other insects also disappear, and the reason is — a reduction of habitats and climate change.
The situation is so severe that the British government has launched a five-year project Insect Pollinator Initiative value of 10 million pounds, which aims — to find out the causes of the extinction of bees and other insects. Search for the answer to this question will deal with several universities and research organizations.
For example, employees University of Dundee check to see whether certain pesticides damage the nervous system and the bees are deprived of any opportunity to perform insects dance, by which they show congeners exact location of feed source. And experts from University of Bristol find out what the most suitable environment for bees: the urban environment or monoculture of cereals in rural areas.
Until now, scientists have found it difficult to explain why the bees are dying. Among the main reasons called Israeli acute paralysis virus, tick Varroa, treatment of plants with pesticides, loss of genetic diversity in commercial populations and climate change. Experts from the French National Institute for Agricultural Research offer his version: bees kill vegetable monotony. When feeding on pollen from one plant species of insects weakens the immune system, and they can not provide his family due antiseptic protection.
