When I see stuff like : there's no evidence of harmful effects to animals, as long as you keep feeding troughs and all other metallic elements grounded... yeah well... I would prefer to see evidence of thriving animal breeding installations under power lines, because all I know about is counter-examples.

Unfortunately, the places I usually go for a summary of the epidemiological literature turned up dry

That's interesting. So little study of something that is so important economically to such powerful actors as (generally) national-monopoly lines companies... Move along, there's nothing to see here...
