Re: Are enviro-nuts EVER satisfied??
At some point I expect one of these groups to do a study on human output
of carbon dioxide and biological waste with a plan for population
reduction. But the avian influenz HN51, ebola, will take care of THAT
But wait? Another reason not to worry about this study. Aren't we going
to run out of oil by 2050, and costal cities like Boston dissapear into
the ocean due to global warming, washing away all of the platinum,
palladium etc from the streets of Beantown?
Oh no! We're doomed!
