They Do Serve Some Purpose

Though not all of Nature's creatures held in high esteem They do serve some purpose or so it does seem On some species us humans wish only ill And given the opportunity them gladly would kill But that all of Nature's creatures exist for some reason is how it seems to be Though on such an opinion many would disagree I do not know of anyone who would invite a rat or a mouse To live free as a guest in the comfort of their house And i know of plenty who great satisfaction would take On killing a poisonious spider or snake And though by Nature designed for their role to fill Some creatures we only do wish for to kill Though with such an opinion many would disagree This anyway is how it seems to me.
