We (humanity) really only have to worry about 1,150 known asteroids; these are the only ones that can cause significant damage to us. Then out of those, there is a smaller percentage capable of causing catastrophic global climate change and wide-spread extinction. One of these massive asteroids will strike the Earth around every half million years, some obviously causing more damage than others. The SGS (Spaceguard Survey) should be done mapping the majority of asteroids as well as comets that can cause such devastating damage to our planet by 2008.

Not to be a cliché from bad space movies? but it really is just a question of when, rather than if, an asteroid or comet capable of removing humanity from this sphere comes hurdling through the solar system. The real question is can we stop it in time to preserve our species? I don?t think so; the best ?method? they have atm is to push the comet or asteroid using nukes (not direct strikes as it wouldn?t do much damage and could just make the problem worse by splitting the object into thousands of pieces). Maybe in a century we?ll have some way of dealing with killer rocks? but not now.

If we were to see a comet or asteroid this century that is large enough to cause global climate change and wide-spread extinction, humanity would probably be destroyed in the process. There is some small chance you could survive the initial impact (depending on the size of comet or asteroid) but the many years of the sun being blocked out is going to destroy almost any chance of you able to successfully find food/and or hunt for survival. If you somehow managed to get the world to work together, you may just be able to save enough humans by putting them deep underground.

Even then? repopulating the planet with such a small genetic pool seems very unlikely. You may be able to sustain a small pool of humans for x number of years, but eventually (and probably sooner than later) the remainder of the human population will dwindle and dwindle until there simply just isn?t enough genetic variance to sustain a healthy population. More and more kids will start being born with more and more genetic abnormalities until the species eventually inbreeds itself into extinction. And that is story of how Moses saved Egypt from the robots.
