Thanx P_Q_N 1 for your input. Confused don't you think 6th Mass extinction is already underway? Lets not compare enviroment chaos with political propoganda, dude. Confused you may have seen fiction about Smallpox somewhere in Sci-fi channel, which I have never heard about. I dont think Epidemic can bring Mass extinction. Anything may be a 'likely' casuse for a mass extinction, Galactic Collision (here I am not talking about sano tino asteriods, its about galaxy), WMD (most likely, I can explain how; but not here) and if not those two, then climatic catastrophe. Latter is most ignored than anything else but for sure will be 'not less' devastating than former two. DeadBurton, like you I am also pointing 27 years back. Lol Bhoot, ya those are all possibility, and if someday your fantasy comes true and you become president of united states, i hope there will be lots of other possibility as well. You will be working against Nukes proliferation, you will be affirmative at Kyoto protocol to work for reduction of greenhouse gases. Finally you will stop "SIXTH MASS EXTINCTION". How about if Star Wars ever happen, hope you will stop that too. Tyati chai gara la. LA BADAI CHA JAGALTEY MITRA LAI..
