Here, the human factor is puting to much reliance on a single crop. If anything 
make that particuliar crop fail you get a famine. In this case, it was a fungal 
infection that destroyed a potato monoculture. That monoculture was made up of 
effective "clones", or single strain, as you plant potato chunks frome the 
previous crop, and the original stock came from a single location. The infection 
is a natural ocurance, but the monoculture is a strictly human factor.
