-------------------------------------------
Bees, nature’s greatest pollinators, are increasingly under threat from disease, parasites, habitat loss and agricultural pesticides
-------------------------------------------
POLLINATORS OF LEADING GLOBAL CROPS (%) 

Bees 90
Flies 
30 Other species* 6
-------------------------------------------
HOW LOSS OF POLLINATORS WOULD DECREASE GLOBAL CROP PRODUCTION (%) 

7 No effects 
8 Unknown effects
45 Drop of 1-40% in 45% of harvests
12 Drop of 90% in 12% of harvests
28 Drop of 40-90% in 28% of harvests

GLOBAL CROP PRODUCTION (%)

5 Unknown
35 Crops that depend at least in part on animal pollination
60 Crops that do not depend on animal pollination
-------------------------------------------
EXPECTED AGRICULTURE LOSS IN ABSENCE OF ANIMAL POLLINATION (%)

Importance of animal pollination varies substantially among crops, and therefore among regional crop economies
