At the species level, it's been estimated that insect-based pollination, bees pollinating fruit and so on, is something like 190 billion dollars-worth. That's something like eight percent of the total agricultural output globally.
从物种层面来说， 昆虫的授粉过程， 例如蜜蜂给水果授粉等， 据估计大约含有1.9千亿美元的经济价值。 这相当于全球农业总产量 的8%左右。
