> The estimate that humans depend on animal pollination for about one-third of their food is often highlighted in the literature on the agricultural consequences of a much debated decline in pollinator abundance. Indeed, 70% of crops that account for about 35% of all agricultural production depend to varying extents on pollinators for _high-quality and high-quantity_ seed and fruit production. 

However, according to our results the proportion of the total production that can be attributed directly to animal pollination, and that may be lost in the absence of flower visitors, is on the order of 5% (developed world) to 8% (developing world).
