I've always had this thought somewhere in the back of my mind. A premonition. There are far too many human buffoons on this planet; far too many morons walking around, oblivious to their environment, caring nothing for their surroundings or their fellow beings. There are far too many brainwashed, closed-minded, materialistic, selfish people.
At some point in the future - maybe soon, maybe not - Earth will find a way to rid itself of this problem. It should come in the form of "natural disaster", or may actually be merely the result of our arrogance and sense of entitlement that comes naturally to us as humans.
