While look for more information around the domino effect of the loss of the bumblebee and any other links or connections that I may have missed, I have come across some interesting quotes. Although these quotes tell a similar story there predictions are quite helpful in regard to backing up the domino effect and connecting more links such as cows and clovers.
Professor Einstein, the learned scientist, once calculated that if all bees disappeared off the earth, four years later all humans would also have disappeared. No more bees, no more pollination, no more plants, no more animals, no more man.

The safety of England depends on the number of cats she keeps. He proves his proposition thus: Without the aid of bumble-bees the red clover could not be fertilised. Bumble-bees make their nests on the ground, where they are the prey of mice. Cats destroy the mice and give the bees a chance to live.
