Recently, my laboratory at Simon Fraser University conducted a study on farms that produce canola oil that illustrated the profound value of wild bees. We discovered that crop yields, and thus profits, are maximized if considerable acreages of cropland are left uncultivated to support wild pollinators.
最近,我在西蒙弗雷泽大学(Simon Fraser University)的实验室对生产菜籽油的农场进行了研究。研究发现,野蜂能发挥重要价值。我们发现,如果把相当一部分农田留出来不耕作,而是用来为野生授粉昆虫提供生存资料,那么粮食产量和收入就会最大限度地提高。
A variety of wild plants means a healthier, more diverse bee population, which will then move to the planted fields next door in larger and more active numbers. Indeed, farmers who planted their entire field would earn about $27,000 in profit per farm, whereas those who left a third unplanted for bees to nest and forage in would earn $65,000 on a farm of similar size.
野生植物种类繁多,就意味着蜜蜂也会更健康、种类更多,然后就会有更多、更活跃的蜜蜂飞到旁边的种植区。把所有农田种满的农民,每个农场的收益约为2.7万美元(约合17万元人民币),而对于那些面积相当的农场,如果留出三分之一的农田不耕作,而是供蜜蜂筑巢和搜寻食物,其收益则为6.5万美元。
Such logic goes against conventional wisdom that fields and bees alike can be uniformly micromanaged. The current challenges faced by managed honeybees and wild bees remind us that we can manage too much. Excessive cultivation, chemical use and habitat destruction eventually destroy the very organisms that could be our partners.
