Why bumblebees love cats, or, why everything is a system.

There is a famous story along these lines told for the first time by the German biologists Ernst Haeckel and Carl Vogt. As the story goes, the fortunes of England would seem to depend on cats. By nourishing themselves on mice, cats increase the chances of survival of bumblebees, which, in turn, pollinate shamrocks, which then nourish the beef cows that provide the meat to nourish British sailors, thus permitting the British navy—which, as we all know, is the mainstay of the empire—to develop all of its power. T. H. Huxley, expanding on the joke, added that the true force of the empire was not cats but the perseverant love of English spinsters for cats, which kept the cat population so high. In any event, underlying the joke is the simple truth that all living species are connected to one another in some way or other by relationships, visible or hidden, and that acting directly on one species, or simply altering its environment, can have totally unexpected consequences.

Don't fuck with cats.
