I agree and am grateful to the hon. Lady for that helpful contribution.
The point being got at, whether by a poet or a scientist, is that of the 100 crop species that provide 90% of food worldwide, 70 are pollinated by bees. Bees, as we know, transfer pollen from anthers to stigmas, frequently over long distances. Seeds are produced, but, crucially, genetic diversity, so vital to the health of many plant species, is promoted. That service, which perhaps we take too much for granted, is worth in the order of £600 million a year through increased crop yield in oilseed rape and the quality of various fruit and vegetables.
