Mobile phones are one of the most useful inventions of the last 50 years, but not everything that is said about them is good. Mobile phones are usually to blame* for a number of things: from headaches to house fires. One theory even blames mobile phones for the disappearance* of bees!

       The theory is that the bees’ navigation systems are damaged by the radiation* from mobile phones. Bees have a built-in system, and this helps them find their way back to their hives*. But recently, thousands of bees have failed to find their way home.
       The problem was first noticed by beekeepers in America and is a lot more serious than it at first seems. The important thing about bees is that most of the plants in many countries of the world are pollinated* by them. Without bees, the plants can’t grow. Many beekeepers in America and Europe have reported losing between 50 and 70 percent of their bees. Jim Piper, a London beekeeper, was recently asked how the problem was affecting him. “My business has been destroyed by this,” he complained.
       Nobody has proved that this theory is true but it’s a fact that bees are disappearing in very large numbers. And we can do nothing without them. Einstein said that if all our bees disappeared, man would only live for four more years! The situation firstly needs to be tested by the world’s best scientists. If the result proves that the theory is correct, we need to do something about it immediately — before it is too late.
