Moon collide (no more moon)

Have you ever wonder what will the world be when there is no moon at night? I just believe that the moon rock will collide one day with one of the meteor and the whole planet moon was gone. But live in earth will still be the same as we got our lighting facilities, however we will lost the chance to apperciate the moon present. How will it be light living in the land of darkness? Most probably a few zombie will be at the street looking for you.
