Beks, an asteroid hitting the Earth and causing climate change COULD be a man made disaster if the asteroid gets hit by a big glob of space junk we've left up there and that causes it to change course and hit the planet. See, this is why we have to scrap NASA and stop sending stuff up into space. We have to do more recycling! Bring down all that space junk and recycle it into useful items! Save the planet!
