Earth’s insect population shrinks 27% in 30 years

The world has lost more than one quarter of its land-dwelling insects in the past 30 years, according to researchers whose big picture study of global bug decline paints a disturbing but more nuanced problem than earlier research. From bees and other pollinators crucial to the world’s food supply to butterflies that beautify places, the bugs are disappearing at a rate of just under 1% a year, with lots of variation from place to place, according to a study in yesterday’s journal Science.
