Water Water everywhere and not a thought to think
"Out of our model atmosphere of 2,400 litres of water, just about a shot glassful is carbon dioxide put their by humans. And of that miniscule amount, Canada's contribution is just 2% --about 1 ml."
K. For once I'm going to do the global warming believers a favor. Just to show you how fair I am, I'm gonna tell you how to handle this one. Everyone go and buy some really poisonous snake. No really. And I don't care which one. Buyers choice. You like Indian food, buy a cobra. Kill Bill fan? Black mamba is the way to go. Hell, it doesnt even have to be a snake. Lots of scorpions and spiders will do the job just fine.
The next time someone makes this argument I want you to reach into the cage that you have conveniently been carrying with you and carefully brandish your new pet at the skeptic. Ask the skeptic if he would like to pet the pet. Thrust it menacingly in his face. When they object look at them incredulously and say,
"don't be absurd! Your bloodsteam is equivalent to 3 two litre bottles of coke! And this snake's venom is just a teeny tiny teensy weensy droplet of liquid. How could it ever cause your heart to stop, your nervous system to shake, your throat to constrict and make your last moments of life on this planet a veritable buffet of agonising sensations before it sucks you down down down into the inky inky darkness of the beyond? Don't be so gullible. PET MY SNAKE YOU COWARD!!!"
Maybe then he'll get the idea that even if he turns out to be right, It was hardly a self-evident truism.
