Something that kills off 50% of the worlds population must be a pretty big war. And in that case, must be a nuclear war. A a war that kills 50% of the worlds people must have used many nuclear weapons, which can lead to extreme long term environmental damage, to the air, and the water. Civilization would actually be much worse than it is today

Well, you're inferring quite alot there. I didn't say a nuclear war. And yeah, if it were a huge nuclear war that would be really bad long term. So maybe 50% would be a little too much if it were from a war. Or maybe we can just go with a huge drought/ famine/ disease/ whatever. You get the point
