Ladies and Gentleman, I have something to say, we as a global village
should unite against saving the earth!  I can tell that you are asking
why we should destroy the one planet we have, so I will tell you.  
There are those of you among us who would disagree with me fervently
but that is just because you are aliens!  Yes, that is right, all you 
environmentalists are aliens!  Environmentalists have came here in order
prepare the planet for a massive alien invasion that is to occur in the
near future.  As earthlings, we must fight back!  The easiest, most 
effective way to rid our plant of the alien influence is to pollute 
extensively!  If we pollute enough, they will have to leave because 
the environment will become to toxic for them.  As humans, we are far
more tolerant to pollutants than those of the other world.  Do you 
really want aliens taking you over and worst of all, leaving them a 
fresh, pristine, refurbished planet that they can enjoy?  Join the 
cause! Be careful though, because the aliens have even infiltrated
our government.  This explains the odd behaivior of our current vice
president.  So all in all, "DONT DISPUTE! JUST POLLUTE"
