There is a whole host of global worries, natural and man made events that could wipe out modern civilization at the least, humankind itself at worst. Here is a summary of some of them.
I remember reading, back when the asteroids hit Jupiter, that such a body hitting the Pacific Ocean would create a tsunami 10,000 meters high.
For the metrically impaired, that is higher than Mount Everest.
It doesn't take a whole lot of imagination to see what a really big natural catastrophe would do to humans, but relax, and consider the upside:
Even if 99.9% of human beings were to be wiped off of the face of the Earth, there would still be six million of us left, way to many to even be considered an endangered species.
There, doesn't that make you feel better?
