@arsya: This statement is often heard, but it falls short of being accurate. If all bees, not just honey bees but the solitary bees, wasps, and the like all disappeared tomorrow, our diet would change, and our environment would change, certainly. Insect pollinated fruits and vegetables...much, but not all of your garden stock and other crops...for instance, berries, clovers, alfalfa, apples, plums, many nuts and the like would decline in production...some to near zero. What wouldn't change however are all the grains...soybeans, rice, wheat, oats, barley, and other crops like canola, corn, sugar cane, bananas, and more. Our diet would become much less attractive, appealing and diverse, but there would be much to eat. A different question might be, could food producers in the world change gears fast enough to feed billions of people without those foods bees help produce because we have become so dependent on them? That might be the harder question.
