Is the world really coming to an end?

is the world really coming to an end. I heard of stories in the bible that says u will know when there are earth quake after earth quaker, mother against daughter, father against son. Volcanoes are erupting. I keep asking and I know no one really want to think about death. it just spooks me out that we are going through alot of changes so fast in the world. It seems like we are not trying to save our planet. I live in Mississippi.. we have yet to experience an bad earth quake yet. so when the December 21, 2012 comes what will really happen.
