The problem of bee decline

Since the late 1990s, beekeepers around the world have observed 
the mysterious and sudden disappearance of bees, 
and report unusually high rates of decline in honeybee colonies. 

Bees make more than honey - they are key to food production because 
they pollinate crops. 
Bumblebees, other wild bees, and insects like butterflies, wasps, 
and flies all provide valuable pollination services. 
A third of the food that we eat depends on pollinating insects: 
vegetables like zucchini, fruits like apricot, nuts like almonds, 
spices like coriander, edible oils like canola, and many more… 
In Europe alone, the growth of over 4,000 vegetables depends 
on the essential work of pollinators. But currently, 
more and more bees are dying. 
The bee decline affects mankind too. 
Our lives depend on theirs.
