I was browsing throught the lounge when I noticed there wasent anything on dooms day devices, so this is just for talking aout way to destroy or take over are planet. I recently herd about this thing cald a geological polar shift and was like, Oh My God! think off the north and south poles changing places and then picture the geological north and south poles sudely changing places caussing massive thunamies, volcanic eruptions and earthcwakes all over the planet and the oceans to attempt to stay in place covering entire continents.
Oh my God! Think of all the compasses we'll have to replace! That'll cost hundreds, maybe even thousands of dollars world wide!
Or useless (well, not really if you can just remember that the direction you're looking at is the opposite).
I'll have to watch out for "thunamis" "The Earth's magnetic field may flip towards the end of the next millennium according to Danish geophysicists" - physicsworld.com well more like 1000 years but whos counting
super anthrax that only takes a few spores to kill people, instead of the one we have now that takes like 3000 spores
Possibly either the giant dormant volcano underneath Yellowstone (for the U.S. atleast) or the small island off the coast of Africa that'll collapse into the ocean and send a huge tsunami towards us. That's natural disasters anyway, assuming human factors won't destroy all of us first.
