There are several categories of freaks (injury, disease, physical growing
conditions (odd shapes caused by cramped conditions), pollution, natural conditions
and chemicals (water temp. and food source and supply variations, high iron or
manganeese concentrations, etc.), and of course genetics.).  My question is: how
can one tell when pollution is the likely cause of a particular malformation or
color variant?  With some specimens, it seems easy (as in dwarfism due to chemical
pollution, as occurs near pulp and paper plants sometimes, which discharge chlorine
and other nasties), but with many others, it seems rather tricky.  Are there some
general guidelines folks have worked out to help tell the differences between
man-caused, and natural freakazoids?
