Hi all,
Do acid rains have any measurable, negative effect on organic crops, in term 
of the health of people eating those crops?
Put it another way are organic, certified crops tested also for their content 
in toxic materials coming from the sky?
Are there any studies available on this subject?
There seems to be little that the farmer can do about that.
Cheers
