Once, I wanted to annihilate all bedbugs in the world with a snap of a finger (I would even learn how to snap for this very purpose), just disappear them forever at my will. A single use power, nothing more than that, and I don't care what that suppose to do to the environment.
.... I mean if you don't know how to snap, then you never have snapped. For all you know this actually could be your super power and you haven't even bothered to find out. With great power comes great responsibility.
