The world faces a future with little meat and no cotton because of a catastrophic collapse in bee colonies, experts have warned.
Many vital crops are dependent on pollination by honeybees, but latest figures show a third failed to survive the winter in the U.S.
More than three million colonies in America and billions of bees worldwide have died since 2006.
Pesticides are believed to be a key cause of a crisis known as Colony Collapse Disorder (CDD), damaging bee health and making them more susceptible to disease. But scientists do not know for certain and are at a loss how to prevent the disaster. Other potential factors include bloodsucking parasites and infections. Some experts believe bees are heading for extinction. The number of managed honeybee colonies in the U.S. fell by 34 per cent last winter, according to a survey by the country’s Agricultural Research Service, and some commercial beekeepers have reported losses of more than 60 per cent over a year.
In Britain, the latest report into the fate of the estimated 250,000 honeybee colonies is expected this month after losses of up to a third in the last two winters.
Bees are a critical part of the food chain because flowering plants depend on insects for pollination and the honeybee is the most effective.
It pollinates 90 commercial crops worldwide, including most fruit and vegetables – from apples to carrots – alfalfa for cattle feed, nuts, oil-seed rape and cotton.
A world without honeybees would mean a largely meatless diet of rice and cereals, no cotton for textiles, no orchards or wildflowers and decimation among wild birds and animals in the bee food chain.
Bees are worth £26 billion to the global economy, and £200 million in Britain.
