Heck I think I read a article and I can't for the life of me find it. But it said something to the effect of human DNA is corrupted more and more with every generation. At the current rate I think their estimates were just a couple hundred years left before the DNA is so bad it won't be able to make offspring anymore.
Kinda makes sense when you see how genetic diseases become more and more prevalent. That and our poisoned food.
