Repent, for the end is surely near!

Here is a map of 1,400 asteroids NASA is currently tracking. They are classified as "potentially dangerous" because their orbits could coincide with the orbit of Earth and they are big enough to do considerable damage if they collided with us. 

I realize this is a 2D representation of 3D phenomena and it looks more congested as a result, but still, that's a lot of potential death and destruction swirling around our particular galactic neighborhood.
