The biggest threat to mankind. What will end the world as we know ?

Does the world need to be saved ? Are we heading toward an inevitable extinction ? will that be a new generation bomb ? or will it be pollution ? will it be depletion of natural resources ? or will the machines be our killers as it is suggested in many sci-fi stories ?

  • Jun 25 2012: The movie Idiocracy comes to mind as a parable about a very real threat that appears to be manifesting itself.

    Sperm counts have been dropping since plastics became common... so (as I posted below) it may be only men that disappear (parthenogenesis)

    Surely some mad (or very sane) scientist has been tinkering in lab on some kind of pathogen that will wipe most of us out... a karma-germ would be nice if it is going to happen!

    But as for all of us going extinct, it is probable that the last blade of grass on Earth will be eaten by a human. We are pretty darned adaptable!
