Butterfly Beetle

You are, I assume, familiar with the way in which a butterfly, flapping its wings in a rainforest in Java can cause typhoons and tempests on the other side of the world? Good. But have you considered the logical consequence of this? Given that there are countless such Lepidoptera all tirelessly endeavouring to create chaos, why are tempests and typhoons such rare events?

The answer lies with beetles. Toiling away quietly and thanklessly in our defence. Every time a butterfly thoughtlessly wafts its gaudy wings, three or four beetles (their smaller wings necessitate the larger number) beat their own delicately strong wings in such a way as to cancel out the potentially deadly variations in pressure caused by the deadly butterflies. The fact that we still have tempests and typhoons testifies to the fact that their efforts are sometimes in vain, but the fact remains that, without our tiny allies, our planet would be supremely inhospitable.

A similarly constant and unvarying struggle is played out between dolphins (evil) and jellyfish (heroic).
