What percentage of the world's food crops are pollinated by insects?

When you consider cross-pollination, it indicates for the most part honey bees. There was a movie about bees going on strike and then all the vegetation died.

This is true! You would think that such a tiny insect wouldn't be so extemely important to life, but if they died, so would EVERYTHING else. Sometimes butterflies perform cross-pollination but then you wouldn't have the seetness of honey. (Just kidding.)
