Scientists say that global another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying isn't the only serious another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying to humans. Another another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying threat is the falling numbers of insects and the another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying of many species. Scientists say that half of all insects worldwide have been declining since the 1970s. A new another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying is that over 40 per cent of insect species could die out in our lifetime. Researchers said the another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying of insects is decreasing by 2.5 per cent every year. The scientists are calling it an "insect apocalypse". Many species of butterflies, bees and other another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying are now extinct. In the U.K. researchers say 23 bee and wasp another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying have gone extinct in the past century. Scientists say the another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying could trigger, "a catastrophic another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying of Earth's ecosystems". Lead another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying Professor Dave Goulson said a lot of another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying are being killed by pesticides used for farming and gardening. He said fewer another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying of insects might mean we cannot feed people. He told reporters: "Three another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying of our crops depend on insect pollinators. Crops will begin to fail. We won't have things like another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying . We can't feed 7.5 another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying people without insects." He said one of the most another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying trends is the decline of honeybees. In the USA, the another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying of honeybee colonies dropped from six million in 1947 to just 2.5 million in 2014. Professor Goulson warned people that: "We can't wait another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying 25 years before we do anything because it will be too another apocalypse billion bugs collapse extinction insects late major number numbers quarters researcher species strawberries threat warming warning worrying ."
