Mobile phones are one of the most useful inventions of the last 50 years, but not everything said about them is good. Mobiles are frequently blamed for a number of things, from thumb injuries and 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 that is given off by mobile phones. Bees have a built-in system a bit like GPS and this helps them find their way back to their hive. But recently, thousands of bees have failed to find their way home. It is believed they are dying far from their hives. The problem was first noticed by beekeepers in America and is a lot more complicated than it at first seems. The important thing about bees is that most of the crops in many countries of the world are pollinated by them. Without bees, the crops can't continue to 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 ruined by this,' he explained. 'Twenty-nine of my forty hives are now empty.' Nobody has proved that this theory is true but it's a fact that bees are disappearing in very large numbers. And we can't manage without them. Einstein said that if all our bees disappeared, man would only live for four more years! The situation needs to be evaluated by the world's best scientists. If the mobile phone theory is correct, we need to do something about it immediately – before it's too late. сократи этот текст до 60% текст должен быть на английском

Пошаговое сжатие (метод): - Выделил основную мысль: исчезновение пчёл может быть связано с воздействием мобильных телефонов; важность опыления для crops; необходимость научной оценки. - Сохранил ключевые факты и цитаты: связь навигации пчёл с теориями, диапазон потерь 50–70%, цитата Пайпера и долгая оценка Эйнштейна. - Устранил второстепенные примеры и подробности, сгладил формулировки и переписал текст короче, сохранив смысл. - Переформатировал на естественный английский стиль и приблизил длительность к 60% от исходника. Итоговый текст (приблизительно 60% длины, на английском): Mobile phones are among the most useful inventions of the last 50 years, but not everything about them is good. They are blamed for thumb injuries, headaches, and even house fires. One theory even blames phones for bees' disappearance. The claim is that radiation interferes with bees' navigation systems, which help them return to their hive. Recently, thousands of bees have failed to find their way home, apparently dying far from hives. Beekeepers in America first noticed the problem, which is more complex than it seems. Bees pollinate most crops in many countries, so their loss threatens food production. In America and Europe, beekeepers report losing between 50 and 70 percent of their bees. London beekeeper Jim Piper lamented, "Twenty-nine of my forty hives are now empty." While no proof exists, bee disappearance is undeniable, and we can't do without them. Einstein reportedly said that if all our bees vanished, humans would live only four more years. Scientists worldwide should evaluate the situation. If the mobile phone theory is correct, we must act quickly before it is too late.
