The prospect that a global pollination crisis currently threatens agricultural productivity has drawn intense recent interest among scientists, politicians, and the general public [1–5]. To date, evidence for a global crisis has been drawn from regional or local declines in pollinators themselves [6–9] or insufficient pollination for particular crops [9, 10]. In contrast, our analysis of Food and...

Because a sizable proportion of the human diet depends directly or indirectly on animal pollination [5], the issue of how decreases in pollinator stocks could affect global crop production is of paramount importance [6–8]. Using the extensive FAO data set [9], we compared 45 year series...
